2026-01-19Purpose of glass cloth sandblasting tape
Glass cloth sandblasting tape, also known as sandblasting masking tape or anti-sandblasting tape, is a high-strength protective material specifically designed for demanding sandblasting (shot blasting) processes. Its core purpose can be summarized in one sentence: to provide sturdy and reliable masking for precision areas on the workpiece that do not require treatment or require absolute protection during the sandblasting process.The following are its detailed purposes, characteristics, and working principles:1. Main purposesProtect precision machined surfaces: protect threaded holes, precision bearing positions, fine grinding surfaces, sealing surfaces, etc., to prevent damage to dimensional accuracy and surface finish from high-speed sand particles.Selective area sandblasting: On large or complex workpieces, only specific areas (such as welding grooves) are subjected to sandblasting cleaning, while other areas (such as painted surfaces and polished surfaces) are protected.Protect non-metallic components: On the assembly, protect rubber seals, plastic parts, window glass, etc. to avoid being damaged or embedded by sand particles.Form clear boundaries: Create neat and sharp treatment boundaries in areas where different coatings need to be sprayed or local treatments are required.Temporary protection: Provides temporary wear-resistant protection during workpiece transfer or between processes.2. Core Features (Why it is competent)Completely different from ordinary tape, glass cloth sandblasting tape is designed to withstand extreme physical impacts:Extremely high wear and puncture resistance: The substrate is a tightly woven glass fiber cloth, which possesses exceptional strength and toughness. It can effectively resist repeated impacts and cutting from high-speed sand particles (such as steel grit, corundum, quartz sand, etc.) traveling at speeds up to hundreds of meters per second, making it less prone to puncture or tearing.Strong adhesion & clean peeling: Coated with a special strong acrylic adhesive, it can firmly adhere to various surfaces such as metal, plastic, and glass, without warping or falling off even under the vibration and impact of sandblasting. After sandblasting, it can be relatively cleanly peeled off with minimal residual adhesive.A certain degree of flexibility: The glass cloth substrate possesses a certain degree of flexibility, allowing it to conform to surfaces with slight curvature.Weather resistance: It usually has certain temperature resistance, moisture resistance, and UV resistance, and can adapt to different workshop environments.3. Typical application industriesNaval architecture and marine engineering: Protect the precision mating surfaces of propeller shafts and marine engines, and perform segmented sandblasting on the steel plates of the hull.Heavy machinery and steel structures: Before sandblasting for corrosion protection of large welded structural components (such as bridges, cranes, pressure vessels), protect flange faces, bolt holes, etc.Aerospace: Protect critical areas during local sandblasting strengthening or cleaning of aircraft components.Automobile manufacturing and maintenance: Especially when performing local sandblasting and rust removal on the frame and chassis, protect the surrounding components.Wind power industry: Protecting the precision surfaces of components such as wind turbine main shafts and gearboxes.Surface treatment and painting industry: This is its core application scenario, serving as the standard consumable for all high-quality pre-treatment (sandblasting) processes in spray painting.4. Difference between ordinary tape and the tape you have previously knownSimply put:Polyimide tape is a "fire-fighting suit" that protects against high-temperature flames.Glass cloth sandblasting tape is a "bulletproof vest" that protects against bullet impacts.5. Usage SuggestionsSurface cleaning: Ensure that the workpiece surface is dry, oil-free, and dust-free before pasting to ensure optimal adhesion.Pressing the edges: After pasting, be sure to press the edges of the tape firmly with a scraper or your fingers, especially at the corners, to prevent sand particles from cutting in from the edges.Timely peeling: After sandblasting, it is recommended to slowly peel off at a certain angle as soon as possible (before the adhesive is fully cured) to achieve the cleanest peeling effect.Specification selection: Based on sandblasting pressure, sand type, and roughness, select products with different thicknesses (such as 0.2mm, 0.3mm, etc.) and strengths.Summary: Glass cloth sandblasting tape is an essential tool in the surface treatment industry for achieving "selective sandblasting" and "precise protection". It ensures that critical parts of the workpiece remain intact through its own robust "sacrifice", and is a crucial link in guaranteeing the quality of subsequent coatings and product functionality.What kind of tape is resistant to high temperatures and leaves no residue
The key lies in whether the tape leaves adhesive residue after being removed, which is primarily determined by its "adhesive (back adhesive)" type and "usage conditions" (temperature, time, surface material).Below, we present a categorized introduction to several mainstream tapes that are resistant to high temperatures and do not easily leave adhesive residue:1. Best choice (high temperature and almost no residual adhesive)This type of tape utilizes silicone pressure-sensitive adhesive or a special formula and is specifically designed for clean removal after exposure to high temperatures.Polyimide high-temperature tape (Goldfinger tape)Material: Brown/Amber film.Temperature resistance: Long-term temperature resistance up to 260°C, and short-term temperature resistance up to over 300°C.Features: One of the most commonly used and reliable options. It often comes with release paper on the back. Its silicone adhesive formula, when used correctly (such as removing it while hot after high temperatures), usually leaves no residue. It is widely used in SMT reflow soldering, wave soldering, circuit board protection, and coil winding.Note: Poor-quality products may still leave residue due to inadequate glue formula.Teflon high-temperature tape (PTFE tape)Material: White/Black, with an extremely smooth surface.Temperature resistance: Capable of withstanding temperatures up to 260°C - 300°C.Features: Excellent anti-adhesive property, inherently non-stick material, thus leaving almost no residue. Commonly used in thermoplastic sealing machines, iron soleplates, baking molds, and chemical anti-adhesive applications. The disadvantage is its low strength and relatively high price.2. Cost-effective choice (for medium and high temperatures, leaving no residue when used correctly)PET green/white high-temperature tapeMaterial: green or white polyester film.Temperature resistance: approximately 130°C - 180°C.Features: Good insulation and a certain degree of toughness. PET tape specifically designed for electronic and electrical purposes (not ordinary packaging tape) uses high-temperature resistant glue. After being used at rated temperature and time, it can be removed without leaving any residue. It is commonly used for circuit board masking, coil insulation, and milder soldering protection.3. Dedicated for shielding protection (medium and low temperature, special formula)High-temperature resistant masking tapeMaterial: crepe paper + special high-temperature resistant glue.Temperature resistance: Varies from 80°C to 220°C depending on the grade.Features: Designed specifically for masking processes such as spray painting, paint baking, and sandblasting. High-quality high-temperature masking tape (such as automotive spray painting grade) should be used within the specified temperature and time range (usually clearly indicated), and should not leave adhesive residue after removal. Using it for too long or at excessive temperatures can result in adhesive residue.Applications: automotive painting, furniture baking paint, glass/ceramic spraying and color separation.Selection and use of core recommendationsDetermine temperature and duration: Ask yourself "What temperature tolerance is required? How long does it need to last?" Choose a tape with a temperature tolerance range higher than your actual needs.Choose specialized tape: Do not substitute with regular tape. For electronic soldering, choose polyimide tape; for painting, choose high-temperature masking tape.Purchase premium brands: Glue formulas from renowned brands such as 3M, Nitto, Tesa, Saint-Gobain, etc., are more stable and carry a lower risk of leaving adhesive residue. Be wary of products with excessively low prices.Test! Test! Test!: Before large-scale or critical applications, it is essential to conduct small-scale testing in inconspicuous places to evaluate its temperature resistance and the effect after removal.Remove while hot: Some high-temperature tapes (such as polyimide tape) will solidify after cooling, making them harder to remove and prone to leaving adhesive residue. It is recommended to remove them while they are still warm, before they have fully cooled down to room temperature.To directly answer your question, after specifying the required parameters (temperature, time, surface), select the corresponding type ofhigh-quality high-temperature resistant tape and operate it according to its usage specifications (especially the timing of removal), and youcan achieve high temperature resistance without leaving adhesive residue. For the most demanding dust-free environments(such as semiconductor and optical industries), there are more specialized ultra-low residue tapes available for selection.MLCC upper/lower tape coated with silver tape
In the production of MLCC (Multi Layer Ceramic Capacitors), the "upper/lower tape" and "silver dipping tape" you asked about are two completely different specialized tapes that play important roles in packaging, transportation, and electrode manufacturing, respectively.📦 Cover/Base TapeThis type of tape is mainly used for packaging and transportation of electronic components. They are used in conjunction with paper carriers to securely seal small components such as MLCC in the grooves of the carrier for accurate picking on automated surface mount machines.Core requirement: To prevent tiny MLCC from being electrostatically broken down, this type of tape usually needs to undergo anti-static treatment. At the same time, they also need to have stable peeling force (pulling force) to ensure that they can be smoothly peeled off on the automatic mounting machine without leaving irregular tear marks.Main suppliers: Major players in the industry include Japan's Mattei Group, Jiemei Technology, and some professional manufacturers such as Taicang Qunte Electrical Materials.🎨 Silver Termination TapeThis type of tape is used in the "sealing" process of MLCC manufacturing to protect the ceramic body parts that do not require sizing. Due to the need to be exposed to high temperatures, it has high requirements for heat resistance.Working principle: When silver paste (or copper paste) is applied to the end of MLCC to form an external electrode, this tape tightly wraps around the rest of the capacitor, providing shielding and protection. Subsequently, the components with adhesive tape will enter a high-temperature oven or sintering furnace for processing.Core technical requirements:High temperature resistance: This is the most critical characteristic. After high-temperature treatment at 200 ° C to 260 ° C, the performance of the tape must remain stable and cannot deform or melt.No residual adhesive: When peeled off after the process is completed, it must be 100% residue free. Any residual adhesive will affect the performance or appearance of MLCC.Flexible and snug: The tape needs to be able to tightly adhere to the tiny surface of MLCC, providing reliable shielding for subsequent electroplating, sintering, and other processes.Main suppliers: The main suppliers in the market include Shenzhen Yizhong Technology Co., Ltd., Dongguan Xinpengda Adhesive Products Co., Ltd., Haojia Enterprise Co., Ltd., Shenzhen Youtu Technology, etc.⚙️ New choice in technology: thermal foaming tapeIn the "silver dipping" process, in addition to traditional silver dipping tape, a more advanced thermal foaming tape is becoming popular.Traditional silver coated adhesive tape needs to be manually or mechanically removed after protection, while thermal foam tape utilizes its own characteristics to rapidly expand in volume at specific high temperatures (about 190-210 ° C), thereby automatically and completely eliminating the stickiness and achieving automatic unloading of components. This characteristic makes it more suitable for high-precision automated production and can effectively avoid the physical damage that traditional tape may cause to fragile ceramic bodies or electrodes when torn off, especially when dealing with small-sized MLCCsBlue PET high-temperature adhesive tape
Blue PET high-temperature tape is a very important special tape in the fields of electronic manufacturing, electrical insulation, and industry. It usually refers to a type of adhesive tape made from polyester film (PET) as the substrate, coated with high-performance silicone pressure-sensitive adhesive (or acrylic adhesive), and subjected to high temperature treatment.Below is a detailed introduction to its features, applications, and key points for purchasing:Core features and advantagesExcellent high temperature resistance: This is its most important feature. It can usually withstand high temperatures of 130 ° C to 260 ° C for a long time, and even higher temperatures in an instant (such as 300 ° C+).

Some blue colors are also used to change color (such as becoming lighter) after high temperatures to indicate that they have undergone a high-temperature process.Easy to tear and leave no residue: High quality tape can be cleanly peeled off after high-temperature protection, without leaving any adhesive stains on the surface of the object being pasted.Main application areasManufacturing of electronic circuit boards (PCBs):Wave soldering and reflow soldering: used to cover (mask) gold fingers, connectors, or specific areas that do not require soldering.SMT patch: Fixed components or used as temporary protection.PCB Splitting: Protect edge circuits during PCB cutting.Electrical insulation:Used for interlayer insulation and bundling of motors, transformers, and inductor coils.Winding and labeling of wires and cables.High temperature spraying and surface treatment:Protect specific areas of the product surface during processes such as painting, sandblasting, and posite material processing:Used as an isolation film or protective film during the curing process of carbon fiber and fiberglass products.Other industrial uses: such as lithium battery manufacturing, heat sealing, temporary fixation in high-temperature environments, etc.Key parameters to pay attention to when making a purchaseSubstrate thickness: Common thicknesses include 25 μ m (1mil), 36 μ m, 50 μ m, etc. The thicker, the higher the mechanical strength, but the flexibility may slightly decrease.Adhesive type:Silicone: The most common and has the best temperature resistance (up to 260 ° C or above), but its initial adhesion may be relatively low and its price may be higher.Acrylic adhesive: has good initial adhesion and adhesion retention, slightly lower temperature resistance (usually 130 ° C-180 ° C), and relatively affordable price.Total thickness: including the total thickness of the substrate and adhesive layer.Temperature resistance level: It is necessary to confirm the long-term use temperature and short-term peak temperature to ensure that your process requirements are met.Width and length: Choose the appropriate roll size according to the usage scenario.Release paper/release film: protect the adhesive surface and ensure that the tape remains sticky before mon Brands and MarketsInternationally renowned brands: 3M (such as 3M 5413, 3M 5419 series), Nitto, Tesa, Teraoka, etc., with reliable quality but high prices.Domestic brands: China also has many excellent manufacturers with high cost-effectiveness, such as Shiyi, Yongle, Fengzhao, etc., which have performed well in meeting industrial demand.Usage recommendationsSurface cleaning: Before pasting, ensure that the surface to be pasted is dry, clean, and free of oil stains.Moderate pressure: Apply even pressure during pasting to ensure that the tape is in full contact with the surface without any bubbles.Environmental testing: Before mass use, it is best to conduct small-scale testing under actual working conditions to confirm its temperature resistance, peel strength, and residual adhesive condition.In summary, blue PET high-temperature tape is a key material that connects "high-temperature processes" and "precision protection". When choosing, please carefully check the product specification sheet (TDS) or request samples from suppliers for testing based on your specific application scenario, temperature requirements, and budget to ensure the most suitable product is selected.Teflon glass cloth tape
Teflon glass cloth tape.This is a composite tape that combines a high-performance coating of PTFE, a sturdy substrate of fiberglass cloth, and a high-temperature resistant silicone adhesive, making it the "high-performance armor" of industrial tape.Core three-layer structureCore role of hierarchical materialsSurface PTFE (polytetrafluoroethylene) is non stick, wear-resistant, chemical resistant, and has low frictionSubstrate glass fiber cloth provides strength, high temperature resistance, tear resistance, and dimensional stabilityBottom layer organic silicon pressure-sensitive adhesive resistant to high temperature bondingFive core characteristicsExcellent high temperature resistanceContinuous use: -70 ° C to+260 ° C.Short term peak: can withstand instantaneous high temperatures of up to 300 ° C.Stable physical properties at high temperatures, without melting or dripping.Excellent non stick and demolding propertiesAlmost all viscous substances (hot melt adhesive, resin, paint powder, food) cannot permanently adhere and are easy to clean.Strong chemical corrosion resistanceIt can resist the vast majority of acids, alkalis, solvents, and oils, protecting equipment from corrosion.Excellent mechanical performanceGlass cloth provides high strength, tensile strength, puncture resistance, wear resistance, and long service life.The surface friction coefficient is extremely low, suitable for situations that require sliding.Reliable electrical insulationIt can maintain good insulation performance even in harsh environments such as high temperature and humidity.Main application scenarios (by industry)Typical Industry ApplicationsElectronic and electrical high-temperature wire harness wrapping, iron base plate, heating tube insulation, circuit board wave soldering shieldingPackaging and plastic heat sealing machine knife wrapping (one of the main uses), plastic hot pressing molding demolding, conveyor belt anti stickingHigh temperature shielding protection for surface treatment spraying, electrophoresis, powder spraying, and welding splash protectionAnti sticking and high temperature resistant liners for the rollers of textile printing and dyeing hot stamping machines and shaping machinesFood industry baking conveyor belt, drying rack anti sticking (food contact compliance needs to be confirmed)General industrial repair or protective coating for corrosion resistance, wear resistance, and insulationHow to use it to achieve the best effect?This is the key to determining the lifespan and effectiveness of the tape.surface pretreatmentIt is necessary to ensure that the adhesive surface is absolutely clean! Oil free, dust-free, rust free, and water free.Thoroughly clean and air dry with solvents such as alcohol and acetone.Correct pasting processTemperature: The best bonding effect is achieved at room temperature or slightly above room temperature (such as 21 ° C-40 ° C).Method: Starting from one end, slowly pull and stick while applying pressure evenly with a scraper or hand to expel all bubbles.Overlap: If multiple splices are required, there should be an overlap of approximately 10-15mm.The crucial 'thermal curing'After pasting, do not immediately put it into peak high temperature use.Correct steps: Gradually raise the temperature to the working temperature (for example, first raise to 150 ° C and hold for 30 minutes, then raise to the working temperature), allowing the silicone adhesive to fully cure and form the strongest adhesive force.Maintenance and replacementRegularly inspect the surface for wear, scratches, or decreased adhesion.When the surface PTFE layer is severely worn and exposes the glass cloth, or loses its non adhesiveness, it should be replaced in a timely manner.Key points for purchasingCheck parameters: Focus on thickness, width, temperature resistance level, and peel strength.Choose color:Brown/Amber: The most common and universal type.White: Other fillers (such as titanium dioxide) may have been added, and the non stickiness may be slightly different, sometimes making it easier to detect stains.Sample testing: For critical applications, it is essential to first purchase small samples for testing under actual operating conditions.Brand recognition: Choose reputable industrial brands for more stable mon Problems and MisconceptionsQ: Can it be used for non stick pot repair?A: Not recommended! Although the materials are the same, household non stick pans require a dense, uniform coating and a strong bond with the substrate. Tape cannot meet the physical requirements for food safety and long-term cooking, and is prone to peeling off when exposed to high temperatures, posing a safety hazard.Q: Why does the newly applied tape curl or bubble when heated?A: The most common reason is that the surface is not clean or has not undergone "heat curing". Please strictly follow the above pasting and curing steps.Q: What is the difference between it and ordinary high-temperature resistant masking tape?A: A world of difference. Ordinary masking tape (such as washi tape) typically has a temperature resistance of no more than 200 ° C and is not resistant to chemical corrosion, tearing, low friction, or stickiness. Teflon glass cloth tape is a solution to meet extreme and multifunctional needs.If you can provide specific application scenarios (such as what devices are used for, what problems are solved, working temperature, and environment), I can provide you with more accurate selection and usage recommendations.PET-based double-sided adhesive tape

Adhesiveness depends on the adhesive, while thickness mainly affects filling and cushioning.Misconception 2: Ignoring surface treatment → For difficult-to-stick plastics, directly attaching without treatment will inevitably fail. It is essential to conduct a surface energy test (using a dyne pen) first.Misconception 3: Focusing solely on initial tackiness → Long-term reliability (tack retention, aging resistance) is more crucial, necessitating aging testing.Misconception 4: Release paper is not important → Mismatch in release force is a common cause of decreased yield in automatic placement.Summary and Final RecommendationsPET double-sided tape is the cornerstone material for addressing the bonding needs of "thinning, precision, and automation". It is not a standard product, but rather a customized solution that needs to be selected according to the application.防静电PI胶带
We specialize in anti-static PI tape. This is a high-end specialty tape that combines high temperature resistance, high insulation, and electrostatic discharge/shielding functions. It is a key material for protecting sensitive electronic components and ensuring production yield.The core overview is that anti-static PI tape is made by coating an anti-static adhesive on a high-performance polyimide film substrate, or by surface treating the substrate (such as coating with an anti-static coating).PI substrate: It is a "gold standard" high-temperature resistant insulation material, renowned for its excellent heat resistance, mechanical strength, and chemical stability.Anti-static function: Designed to address the issue of electrostatic discharge in electronic manufacturing, it prevents damage to integrated circuits, optoelectronic components, etc. by safely discharging or shielding electrical charges.Key Features and Advantages: Ultimate High Temperature Resistance:The PI substrate itself can withstand temperatures ranging from -269°C to 260°C for extended periods, and can endure temperatures exceeding 400°C for short periods. This enables PI tape to easily handle demanding processes such as reflow soldering, wave soldering, chip packaging, and high-temperature baking.Excellent electrical performance:In addition to being an excellent insulator (high dielectric strength), its anti-static version, through technical means, maintains its surface resistivity within a specific anti-static/static dissipation range (typically 10⁴ ~ 10¹¹ Ω/sq), ensuring that it neither accumulates charges due to insulation nor causes short circuits due to conductivity.Excellent mechanical and chemical properties:High strength, tear resistance, puncture resistance, and excellent dimensional stability.It is resistant to most organic solvents, acids, alkalis, and oils, and maintains stable performance even in harsh environments.Diverse ways to achieve functions:Surface anti-static type: An anti-static layer is only applied to the surface of the PI film, while the substrate itself remains insulating. It is primarily used for surface protection and isolation shielding.Overall anti-static type: The PI film itself or the adhesive has undergone special treatment, endowing the entire tape with anti-static properties. After bonding, it can form an electrostatic discharge channel.Key performance parameter: substrate: polyimide filmColor: Typically amber (tea color), but also available in black or customized colors.Thickness: Commonly seen thicknesses include 0.025mm, 0.05mm, 0.075mm, 0.1mm, etc., which are very thin and lightweight.Long-term temperature resistance: -269°C ~ 260°C (due to the inherent properties of the substrate, the temperature resistance of the adhesive is typically in the range of 180-200°C).Surface resistivity: This is the core indicator of anti-static performance.Electrostatic dissipation range: 10⁴ ~ 10¹¹ Ω/sq (the most common and practical range)Conductivity range: < 10⁴ Ω/sqInsulation range: > 10¹² Ω/sq (ordinary PI tape)Adhesive type: Silicone pressure-sensitive adhesive is the mainstream due to its best high-temperature resistance; there are also acrylic adhesives, etc.Main application scenarios (specific occasions to address electrostatic issues) PCB/PCBA manufacturing process protection:During the SMT (Surface Mount Technology) and wave soldering processes, it is used to cover gold fingers, specific solder pads, or connectors to prevent solder splatter and electrostatic discharge. After soldering, it can be easily peeled off without leaving any residual adhesive.Cover sensitive areas during circuit board testing and transportation.FPC (Flexible Printed Circuit) manufacturing:Used as a cover film or reinforcement plate for fixation, it protects the circuitry during high-temperature pressing (lamination) while also discharging static electricity.Semiconductor and chip packaging:Used for temporary fixation and protection in processes such as wafer cutting, chip mounting, and wire bonding, to prevent minor ESD damage that could lead to chip failure.Lithium battery manufacturing:Used for tab insulation and fixation during the winding or lamination process of battery cells, as well as insulation protection for battery packs, it meets both high temperature resistance and anti-static requirements, preventing internal short circuits.Aerospace and military electronics:Used for cable bundling, insulation, and static control in situations with extreme temperatures and high reliability requirements.Differentiating Features from Ordinary PI Tape and Other Tapes: Anti-static PI Tape, Ordinary PI Tape (Insulating), PET Tape Core Functions: High Temperature Resistance + Anti-static, High Temperature Resistance + High Insulation, High Strength Stability + Insulation Temperature Resistance Levels: Extremely High (260°C+), Extremely High (260°C+), Medium-High (120-150°C) Surface Resistance: 10⁴~10¹¹ Ω/sq (Controllable), >10¹² Ω/sq (Insulating), >10¹² Ω/sq (Insulating) Typical Uses: Anti-static solder masking, chip packaging, general high temperature insulation, electrical wrapping, screen bonding, nameplate pasting Pricing: Highest, Very High, Medium Buying Points and Brand References: Clarify Anti-static Level Requirements:Do you require electrostatic shielding (to prevent external electrostatic interference) or electrostatic discharge (to conduct away the charges generated by the product itself)? This determines the range of surface resistivity you need. The most common range is 10⁶~10⁹ Ω/sq.Confirm that the temperature resistance matches the process:What is the maximum temperature for your process? Can the adhesive withstand it? Silicone tape has good heat resistance but may have low initial adhesion; acrylic tape has strong adhesion but slightly inferior heat resistance.Pay attention to peel force and residual adhesive:Especially after solder masking applications, clean peeling without residue is required. Choosing a high-quality adhesive system is crucial.Other performance:Is UL certification (such as UL 94 V-0 flame retardant rating) required?Is solvent resistance (such as flux resistance) required?What is high-temperature tape? What are the main types and uses?
In many industrial manufacturing and electronic assembly scenarios, ordinary adhesive tape can fail, melt, or even burn when exposed to heat, causing serious problems. At this point, professional high-temperature adhesive tape is needed. This article will take you to quickly understand the basic knowledge, mainstream types, and key application areas of high-temperature adhesive tape.1、 What is high-temperature tape?High temperature adhesive tape, as the name suggests, is a special type of industrial tape designed to withstand medium to high temperature environments. It is not a single product, but a vast family.Its core characteristics are:Excellent heat resistance: The substrate and adhesive are specially formulated to work stably for a long time within a specific high temperature range (usually from 120 ℃ to over 300 ℃), without melting, shrinking, or losing viscosity.Stable physical and chemical properties: able to maintain good insulation, corrosion resistance, anti adhesion or mechanical strength at high temperatures, meeting the stringent requirements of specific processes.Accurate functionality: Used for critical processes such as shielding and protection, insulation fixation, bundling and sealing, anti sticking and demolding, it is an indispensable auxiliary material for improving product quality and production safety.Simply put, high-temperature adhesive tape is a professional tool for solving the problems of bonding, protection, and insulation in "hot" environments.2、 Comparison of the Four Main Types and Core UsesTo facilitate your quick selection, we have compiled the following four most common types of high-temperature adhesive tapes and their characteristics:Common types, temperature resistance range (long-term), core characteristics, and main application scenariosPolyimide tape(Golden Finger Tape/Kapton Tape) With top-notch high temperature resistance and electrical insulation from 260 ℃ to 300 ℃, the material is lightweight and strong, usually with yellow or dark green release paper. Electronics industry: Protect gold fingers and sensitive areas during PCB board wave soldering and reflow soldering; Insulation of motor and transformer coils.High temperature spray painting: precise masking during car and furniture baking.Teflon tape(PTFE Teflon tape) Excellent anti adhesion and chemical corrosion resistance at 200 ℃ -260 ℃, with an exceptionally smooth surface, extremely low friction coefficient, and easy cleaning. Packaging and heat sealing: anti sticking layer for plastic bag heat sealing machine and sealing machine.Food industry: drying line, conveyor belt anti sticking.Chemical industry: anti-corrosion sealing gaskets for reaction vessels and pipe openings.PET tapePolyester film tape has good balance between 120 ℃ and 180 ℃, excellent insulation, solvent resistance, and dimensional stability, and high cost-effectiveness. Electronic components: Fixed, insulated, and protected in medium temperature environments.Lithium battery manufacturing: cell bundling and pole ear fixation.General high-temperature shielding.Fiberglass tape has extreme high temperature resistance, thermal insulation, and fire resistance from 200 ℃ to 600 ℃. The substrate is fiberglass woven cloth, which has high strength but is not usually used for precision insulation. Heavy industry: High temperature pipeline wrapping, boiler insulation, welding operation shielding.Heat sealing cutting: protection of the heat sealing blade edge of packaging machinery.Thermal insulation protection.3、 How to make a preliminary selection?Faced with multiple types, you can follow a simple "three-step method" for initial screening:Temperature setting: What is the maximum temperature for my process? (This is the primary screening criterion)Function: What function do I need the most? Is it insulation (choose polyimide/PET), anti sticking (choose Teflon), shielding (choose polyimide/PET), or bundling insulation (choose fiberglass)?Fixed surface: What material surface does the tape need to be attached to? (Smooth, rough, curved?) Do you need no residual glue?Professional tip: The above are basic classifications. In practical applications, there are more detailed products under each type (such as different thicknesses, adhesives, single/double-sided tapes, etc.). The most reliable way is to provide you with specific process parameters (temperature, time, pressure, substrate, etc.), consult our technical engineers, and obtain customized selection recommendations.summaryHigh temperature adhesive tape is the "behind the scenes hero" in precision manufacturing and industrial production. Choosing the right type not only ensures the smooth progress of the process, but also improves product yield and ensures operational safety. Understanding their differences is the first step towards efficient and professional production.How about Ruili high-temperature resistant tape?

For regular use, Ruili is fully capable.PET transparent high-temperature masking tape
PET transparent high-temperature masking tape "is another key material for masking and protection tasks that require high transparency and excellent dimensional stability in the medium to high temperature range.It perfectly fills the gap between ordinary masking tape (not heat-resistant) and glass cloth tape (opaque, thicker).The following is a comprehensive analysis of PET transparent high-temperature masking tape:Core Features and AdvantagesHigh transparency and visibility: the biggest advantage! During the masking period, it is possible to clearly observe the patterns, text, or status of the covered area, facilitating precise alignment and process inspection.Excellent dimensional stability: PET (polyester) substrate has extremely low shrinkage rate at high temperatures, which can maintain clear shape and edges, and prevent deformation or warping of shielding boundaries due to heat.Good temperature resistance: It can usually withstand 130 ℃ -150 ℃ for a long time, and the short-term peak can reach 160 ℃ -180 ℃. This covers the temperature of most industrial processes such as baking paint, powder coating curing, and electronic component packaging.High strength and puncture resistance: PET film has good mechanical properties, high tensile strength, resistance to friction and slight scratching.Flat and smooth surface: easy to clean and can provide smooth coating edges, suitable for spray masking with surface smoothness requirements.Stable chemical inertness: Has good resistance to common solvents, coatings, and oils.Typical application scenarioselectronic product:LED modules and display panels: When applying glue or spray protection, it is necessary to observe the internal structure.Partial protection of PCB board: protects specific components from being affected during soldering or spraying of three proof paint, and allows observation of solder joints.Glass panel, touch screen: Protect the main window area during border spraying or processing.Industrial spraying and surface treatment:Automotive and home appliance parts baking paint: It is necessary to protect the threaded holes and precision surfaces, and observe the original logo or identification.Secondary processing of plastic parts: such as partial electroplating and UV spraying for masking.Signage and Decoration Industry: When creating complex multi-color patterns, it is used for layered masking due to its high precision and non deformation.High temperature label substrate: It can be used as a high-temperature resistant printing parison with other high-temperature masking tapesCharacteristics: PET transparent high-temperature tape, polyimide brown tape, glass cloth tapeExtremely high transparency, completely transparent, brown semi transparent, completely opaqueMedium to high temperature range (~130-150 ℃), very high (~260 ℃), highest (~180-250 ℃+)High mechanical strength (tensile, puncture resistance), high (tear resistance), extremely high (wear resistance, tear resistance)The substrate has good flexibility, but it is also very stiff, very snug, and thickCore advantages include transparency, dimensional stability, high-precision ultra-high temperature, ultra-thin, electrical insulation ultra-high temperature, and super strong mechanical protectionThe main purpose of shielding is to provide visibility for medium to high temperature spraying, electronic protection for ultra-high temperature welding (wave soldering), precision circuit protection for heavy-duty welding, sandblasting, and extreme environmental protectionSelect key parametersTemperature resistance level: Confirm the long-term use temperature and peak temperature, which must be higher than your process temperature.Adhesive type:High temperature resistant acrylic adhesive: the most commonly used, balancing adhesion, temperature resistance, and final cleaning and peeling properties.Silicone: Higher temperature resistance, but may have lower initial adhesion, suitable for special extreme high temperatures.Thickness: commonly ranging from 0.035mm to 0.1mm. The thinner the thickness, the better the adhesion and the clearer the edges; The thicker, the stronger the protection.Peeling force and residual adhesive control: Choose a model designed for "shielding protection" to ensure clean peeling without residual adhesive after specified time and temperature use. This is the core of measuring the quality of masking tape.Brand and Model:International brands: 3M (such as 3M 5419 series), Tesa, Nitto (Nitto) all have professional series.Domestic brands: There are also many reliable choices, and when choosing, pay attention to specific parameters and user evaluations.Width: Choose the appropriate roll width based on the shielding area to improve efficiency.Usage tips and precautionsSurface cleanliness: crucial! Before pasting, thoroughly clean with solvents such as isopropanol (IPA) to ensure that there is no oil, dust, or water.Paste and compact:Starting from one end, slowly adhere to avoid the formation of bubbles.After pasting, use a scraper or fingers to apply pressure, especially on the edges, to ensure a tight seal and prevent the paint from seeping in.Temperature and time control: Do not exceed the upper limit of the tape's nominal temperature and time, otherwise polymer aging will cause brittleness, difficulty in tearing off, or severe adhesive residue.Removal timing: It is recommended to tear off the workpiece immediately when it has cooled to room temperature or is warm. At this point, the tape has the best performance and is easiest to peel off cleanly. Avoid tearing at extreme high or low temperatures.Testing first: Small area testing must be conducted on new substrates or processes to verify their adhesion, chemical resistance (compatibility with the coating/solvent used), and peel off effect.Summary: PET transparent high-temperature masking tape is the best choice for you to provide precise and visible protection for medium to high temperatures. It perfectly balances the requirements of transparency, temperature resistance, and high-precision masking. If your working temperature exceeds 150 ℃ or you need to resist physical wear (such as sparks, sandblasting), you should consider upgrading to polyimide tape or glass cloth tape.Acrylic foam double-sided tape
Acrylic foam double-sided tape "is a very important category of industrial tape, which combines high-performance acrylic adhesive with foam substrate to create a bonding solution with excellent comprehensive performance. It is irreplaceable by traditional liquid adhesives and ordinary tape in many fields.Below is a comprehensive analysis of its structure, characteristics, types, applications, and selection points.1、 Core Structure and Working Principle: A Exquisite 'Sandwich'Foam substrate (intermediate layer):Material: Usually polyurethane foam, polyethylene foam, or acrylic foam. Each material varies in softness, density, temperature resistance, and solvent resistance.Core functions:Buffer and shock absorption: absorb impact and vibration energy, protect adhesive components.Filling gaps: capable of filling small unevenness, gaps or tolerances between two adhesive surfaces, achieving full surface contact, which is not possible with hard tape (such as PET tape).Stress dispersion: Uniformly dispersing the adhesive force over a larger area, reducing stress concentration caused by thermal expansion, contraction, or deformation, and improving long-term reliability.Sealing: It has a certain degree of dust, moisture, and sound insulation effects.Adhesive layer (upper and lower layers):Material: High performance acrylic pressure-sensitive adhesive.Core advantages:Excellent weather resistance: resistant to ultraviolet rays, oxygen, and moisture, long-term outdoor use (such as cars, outdoor signs) will not easily yellow, powder, or lose stickiness, and the lifespan can reach several years or even more than ten years.Excellent adhesion: Strong creep resistance under sustained stress, not easy to slip or detach.Wide material adaptability: It has good initial and final adhesion to various materials such as metal, plastic, glass, sprayed surfaces, composite materials, etc.Wide temperature range: The working temperature range can usually reach -40 ℃ to 90 ℃ or even higher.Release paper/film (protective layer): High weight release paper is usually used, which is convenient for manual or die-cutting processing.2、 Main features and advantages (compared to traditional tape/glue)Excellent comprehensive performance: balancing high adhesive strength, elastic cushioning, and long-term durability.Easy and efficient construction: tear and paste immediately, no need for mixing or curing, clean and odorless, can greatly shorten assembly time and improve production efficiency.Solving complex problems: particularly adept at handling bonding scenarios with uneven surfaces, large thermal expansion differences, and vibrations.Beautiful appearance: The tape thickness is uniform, and it looks neat and tidy after installation, achieving a "seamless" installation.3、 Main types and application areasAccording to the performance focus of foam substrates and adhesives, they are mainly divided into the following categories:Universal acrylic foam tape:Features: Balancing viscosity, thickness, and cost. Foam has a medium density and good compression resilience.Application: The most common. Used for indoor and outdoor signage installation (such as acrylic letters, metal letters), decorative strip fixation, lightweight building material assembly, and household appliance bonding.VHB ® (Very High Bond) tape (a representative product of 3M, which has become synonymous with the industry):Features: Ultra high strength acrylic foam tape. Its high bonding strength can directly replace mechanical fastening methods such as rivets, screws, and spot welding in many applications, achieving "structural bonding".Applications: fixing metal panels for building curtain walls, assembling elevator cars, assembling refrigerated truck cars, bonding heavy machinery equipment panels, and installing interior parts for rail transit.Ultra thin/medium thick foam tape:Features: Thickness between 0.2mm and 1.0mm, used in situations where small gaps need to be filled and a smooth appearance is required.Application: Internal components of mobile phones/electronic products (fixing batteries, buffering FPC/PCB, filling gaps for dust prevention), film switches, medical device assembly.Flame retardant foam tape:Features: The foam substrate and adhesive have undergone special treatment and meet the UL94 V-0 flame retardant rating.Application: Places with strict fire prevention requirements, such as elevator interiors, public transportation interiors, and electrical cabinets.Thermal/conductive foam tape:Thermal conductive type: Adding thermal conductive particles to the adhesive layer or foam, used in situations that require heat dissipation and shock absorption fixation, such as the installation of certain LED modules and power devices.Conductive type: Provides electromagnetic shielding (EMI/RFI) function for grounding and shielding of electronic device enclosures.4、 How to choose and use key pointsClarify the bonding object: the most important step. Confirm that the surface energy of two materials (such as painted metal glass and plastic wall) directly affects the bonding effect.Evaluate the usage environment:Indoor or outdoor? Outdoor use must choose acrylic adhesive with excellent weather resistance.Are there any drastic temperature changes, ultraviolet radiation, humidity, or chemicals present?Is there continuous vibration or impact?Determine key performance requirements:How strong adhesive force is needed? Lightweight decoration or heavy-duty structure?How much gap do I need to fill? Select the appropriate thickness of foam based on the unevenness or tolerance of the bonding surface.Do you need any special features? Such as flame retardancy, thermal conductivity, and electrical conductivity.Surface treatment: crucial! Ensure that the adhered surface is clean, dry, free of oil, dust, and rust. The best cleaning effect is achieved using isopropanol (IPA).Construction pressure and time: After pasting, sufficient pressure (such as compacting with a roller) should be applied to ensure that the tape is in full contact with the surface. The adhesive strength will reach its maximum value over time (usually 24-72 hours).Test first: Before large-scale application, it is necessary to conduct small sample testing in real materials and environments to verify long-term reliability.5、 The core difference from PET double-sided tapeCharacteristics: Acrylic foam double-sided tape, PET double-sided tapeBase material core elastic foam (three-dimensional structure) hard polyester film (two-dimensional plane)Main functions include filling, buffering, shock absorption, and sealing, while also achieving high initial adhesion and fast bonding on a flat surface with high-strength bonding, and ensuring dimensional stabilityProficient in handling uneven surfaces, tolerances, and shock absorption scenarios, skilled in precise fitting and fixing of smooth and flat surfacesTypical thickness is relatively thick (0.2mm-3.0mm or more) and very thin (0.025mm-0.2mm)Soft to the touch, compressible and hard, incompressibleSummary: PET double-sided tape is like a "tough film", while acrylic foam tape is a "tough sponge". The former is suitable for precise and smooth "surface contact", while the latter is suitable for "body contact" in complex working conditions.summaryAcrylic foam double-sided tape is a revolutionary engineering adhesive material that solves many problems of traditional mechanical fixation and liquid adhesives in terms of shock absorption, sealing, stress management, and construction convenience through its unique "combination of rigidity and flexibility" structure. From the internal fixation of high-end smartphones to the installation of curtain walls in skyscrapers, itspresence is everywhere.Green PET tape
The term 'green PET tape' may refer to several products with different functions in the field of industrial tape, and the color itself is often directly associated with its specific function, which is different from the more versatile white PET tape.Below we will provide a detailed analysis of several common green tapes, with a focus on PET material, while also clarifying other easily confused green tapes.1、 True green PET tape (functional type)This type of tape is based on PET film and dyed green to achieve specific physical functions.Green PET single-sided tape (light blocking/leak proof tape)Characteristic: This is the most common green PET tape. Green dyes can effectively absorb and block specific wavelengths of visible light, preventing light from penetrating or leaking.Main applications:Consumer electronics: widely used in the assembly of liquid crystal displays (LCDs) and bezels for mobile phones, tablets, and laptops. Used to block the light from the backlight module, prevent screen edge leakage, and improve display contrast and visual effects.Optical components: camera modules, sensors, and other components that require protection from stray light pared with white PET: White PET tape usually reflects light, while green PET tape is mainly used to absorb/block light.Green PET double-sided tapeFeatures: Apply pressure-sensitive adhesive on both sides of green PET film. It has dual functions of adhesion and light shielding.Main application: In situations where adhesion is required while strict prevention of light leakage is also necessary. For example, bonding certain components in the phone in place and ensuring that the connection does not transmit light.Other functional green PET tapesAnti static/conductive PET tape: sometimes also made green, used for electronic component packaging, coiling, or in situations where electrostatic damage needs to be prevented.2、 Other green tapes (non PET substrates) often mistakenly referred to as "PET tapes"Many green tapes on the market are not made of PET material, but they are easily confused due to their color and common uses.Green polyimide tape (Kapton tape, green version of gold tape)Substrate: Polyimide (PI), with much better high temperature resistance than PET.Color: The tape itself is usually amber (yellow gold), but the adhesive layer (acrylic or silicone) can be dyed green.Core features: Excellent high temperature resistance (long-term above 260 ℃, short-term up to 400 ℃), flame retardancy, and excellent electrical insulation.Main applications:Wave soldering and reflow soldering of electronic circuit boards: used as high-temperature protection shielding to cover gold fingers or areas that do not require soldering. This is the most classic application of green polyimide tape.High temperature spray painting and baking paint: used for high-temperature spray shielding in the automotive and aerospace industries.Important distinction: When people mention "green high-temperature tape" in electronic welding scenarios, the vast majority refer to green polyimide tape rather than PET tape.Green textured paper tapeSubstrate: Wrinkled paper coated with pressure-sensitive adhesive.Characteristics: Easy to tear, easy to peel off, moderate temperature resistance (usually 60-80 ℃).Application: Mainly used for masking during low-temperature spray painting and coating application, it is very common in decoration and car repair. Its green color may be used to distinguish different temperature resistance grades or viscosities.Green PVC electrical insulation tapeSubstrate: Polyvinyl chloride (PVC).Features: Insulation, flame retardant, wear-resistant.Application: Insulation bundling of wires and cables.

When your application involves medium to high temperature environments and requires reliable protection and easy removal, it is usually the preferred solution.If you have more specific application scenarios (such as what products to use for and what the process temperature is), I can provide you with more targeted suggestions.Die-cutting and processing of double-sided adhesive tape
Die cutting is the process of cutting double-sided tape (or other roll like materials) into specific shapes and sizes through precision molds according to design requirements. This is a crucial post-processing step in industries such as electronics, automotive, medical, and home appliances.Below is a detailed analysis of the die-cutting process for double-sided tape:1、 Core processing flow (standard steps)Material preparation:Substrate selection: Double sided tape itself, commonly such as PET double-sided tape, foam double-sided tape, non substrate double-sided tape (film), VHB tape, etc.Release paper/film: Depending on the process requirements, it may involve single-sided or double-sided release materials.Auxiliary materials: Sometimes it is necessary to composite other materials, such as protective film, conductive cloth, insulating film, etc.Design knife mold:Types of knife molds: Commonly used are carving molds (for integral steel carving, with the highest precision), etching molds (for chemical etching, used for thin materials and complex shapes), and hardware molds (for large batches and simple shapes).Design points: Consider tape thickness, adhesion, and waste disposal methods. The blade angle and height need to be accurately calculated to ensure that the adhesive layer is cut through without damaging the backing paper or only partially cutting.Machine die-cutting:Place the raw material roll on the unwinding reel and pass it through the die-cutting machine.Driven by precision guide rails, the material passes through the die area and is cut into shape under stamping action.This is the most crucial step, which requires extremely high stability of the machine (concentricity, pressure control).Waste disposal:Frame waste removal: Remove waste edges outside the product's appearance.Inner hole waste removal: Remove unwanted adhesive material inside the product (such as the adhesive in the middle circular hole). This step is quite difficult and often requires auxiliary devices such as ejector pins and blowing air.Whether the waste disposal is clean and efficient directly determines the production efficiency and yield rate.Roll up or SMT:Roll up: Roll the die cut product back into a roll shape, usually kept on release paper.SMT: A single piece of die cut product is attached to another release film to form a single product, which is convenient for manual or automated mounting.Quality inspection and packaging:Check the size, shape, burrs, glue overflow, dirt, etc.Conducted in a clean room to prevent dust from affecting adhesive properties.Pack according to requirements for anti-static and vacuum protection.2、 Key Technologies and DifficultiesAnti overflow glue treatment:Double sided adhesive is prone to overflow due to pressure and heat, which can contaminate molds and products.Solution: Use anti overflow adhesive knife mold (special coating or structure), optimize pressure and speed, control ambient temperature, and select appropriate tape.Cutting depth control:Half cut: Only cut through the adhesive tape layer, without cutting the release paper at the bottom layer. This is the most common process with high technical plete cutting: Cut through all layers at once.Inaccurate depth control can lead to difficulty in peeling off the product or difficult waste disposal.Small size and complex shape:With the miniaturization of electronic products, the particle size may be less than 1mm and the shape may be complex (such as irregular shapes, multiple islands).Propose ultimate challenges to the precision of the cutting die, material tension control, and waste disposal technology.Multi layer composite material die-cutting:Die cutting multiple composite materials (such as tape, conductive foam, and protective film) at once, with different physical properties of each layer of material, increases the difficulty significantly.3、 Application scenario examplesMobile phones/tablets: battery mounting frame, screen pad with high foam, camera dust gasket, internal component shielding adhesive, etc.Automotive electronics: sensor fixing gasket, interior panel adhesive, wire harness fixing dical devices: disposable electrode pads, medical dressings backing adhesive, equipment sealing gaskets.Home appliances: nameplate adhesive, sealing strip, shock-absorbing gasket.4、 How to choose a suitable die-cutting supplierTechnical ability: Can you handle the complexity of your product (size, shape, material combination).Equipment level: high-precision rotary die-cutting machine or flat blade die-cutting machine? Do you have automated testing equipment?Clean environment: Whether there is a corresponding level of dust-free workshop.Quality system: Whether there is a sound ISO quality control system and whether the measuring tools are precise.Sample capability: Sampling speed and sample quality are the most direct ways to evaluate its technology.Cost and delivery time: Comprehensive evaluation while ensuring quality.summaryDie cutting double-sided tape may seem simple, but it is actually a comprehensive technology that integrates materials science, precision machinery, mold engineering, and process experience. Its value lies in transforming ordinary coils into key components that can meet specific design functions, high precision, and high reliability.If you have specific products that require die-cutting, the best way is to provide drawings or samples to a professional die-cutting factory for consultation and sampling. They can provide the most suitable process plan and quotation based on your specific needs (materials, dimensions, uses, quantities).Polyimide composite tape
Polyimide composite tape. This is an indispensable "engineering grade" high-performance tape in extreme environments and high-end applications.Core concept: Why do we need 'composite'?Ordinary polyimide tape (such as commonly known as "gold finger tape" or Kapton tape) is usually a single-layer polyimide film+single-sided organic silicone. And "composite" tape is a multifunctional and integrated solution formed by combining polyimide film with other functional materials (such as foam, fiberglass cloth, thermal conductive materials, other adhesive layers, etc.) through precision coating or bonding processes.Core concept: Combining the excellent inherent properties of polyimide (high temperature resistance, high insulation, high strength) with the complementary properties of other materials (buffering, filling, thickening, thermal conductivity) to solve complex application problems that cannot be solved by a single material.Core advantages of polyimide (PI) film (composite basis)Ultimate high temperature resistance: Long term use temperature can reach over 260 ° C, short-term can withstand high temperatures above 400 ° C, and physical properties are stable at this temperature, without melting or dripping.Excellent electrical performance: high dielectric strength, top-notch insulation material, excellent corona resistance.Excellent mechanical properties: high tensile strength, good toughness, bending resistance, and excellent dimensional stability (low coefficient of thermal expansion).Chemical stability: resistant to most organic solvents, oils, and acids.Flame retardancy: typically meets UL 94 V-0 mon Composite Structures and ApplicationsThe following are several typical polyimide composite tape structures:1. PI film+foam+adhesive layerThis is one of the most common composite structures, typically consisting of three or more layers: PI film (surface material)+adhesive+foam (intermediate layer)+adhesive+release paper.Features and advantages:PI film: provides high-strength "skin", responsible for high temperature resistance, insulation, puncture resistance, and solvent resistance.Foam (commonly used silicone foam, polyimide foam, or acrylic foam): provides cushioning and shock absorption, fills gaps, absorbs stress, compensates for tolerances, and improves sealing performance.Double sided adhesive tape: achieves firm bonding.Application Scenario:New energy vehicle battery pack: The insulation, buffering, and bonding between battery cells require insulation, fire resistance, and long-term earthquake resistance.High end motors/transformers: Insulation and fixation between coil windings must withstand high temperatures and electromagnetic vibrations.Consumer electronics: providing insulation, buffering, and certain thermal conductivity gaskets for heating elements (such as CPUs) in limited spaces.Aerospace equipment: The installation of instruments and meters requires shock absorption, insulation, and resistance to extreme temperature cycles.2.

For example:Back material composite: Using PI film as the substrate for double-sided tape to provide high temperature resistance.Adhesive layer composite: using a double-layer adhesive system, such as one layer of high initial adhesive and one layer of high holding adhesive, to optimize performance.The core value brought by "composite"Functional integration: A single material simultaneously solves multiple problems such as insulation, buffering, bonding, sealing, and thermal conductivity, simplifying design and assembly.Reliability improvement: Designed for specific harsh working conditions (high temperature+vibration+high voltage), the system reliability far exceeds simply stacking multiple single materials.Space optimization: Achieve more complex functions with thinner overall thickness, saving valuable equipment space.Process simplification: reduce assembly steps, lower labor costs, and improve production efficiency.How to choose polyimide composite tape? ——Key considerationsClarify the primary and secondary contradictions: What is the main threat in your application environment? Is it high temperature, high voltage insulation, mechanical vibration, or heat dissipation? This determines the focus of the composite structure.Structural decomposition: Request specific structural layer diagrams from suppliers to understand the material, thickness, and function of each layer.PI film thickness: commonly 12.5 μ m, 25 μ m, 50 μ m, etc., determine insulation and mechanical strength.The material and density of the intermediate layer, such as the foam material (silicone, PI foam) and density (kg/m ³), directly affect the buffering and sealing performance.Adhesive type: high temperature resistant organic silicone (>200 ° C) or high-performance acrylic adhesive (lower temperature resistance but stronger adhesion)?Key performance parameters:Temperature resistance level: Long term/Short term.Flame retardant rating: UL 94 rating.Dielectric strength: kV/pression deformation: For structures with foam, this is important and affects long-term sealing performance.Thermal conductivity: For thermal conductive products.Environmental tolerance: Is it necessary to be resistant to cold and hot shock, moisture and heat aging, specific chemicals, or UV?Certification and Compliance: Material certification is crucial in fields such as automotive (such as USCAR), aviation, and rail transit.Main brands and marketsInternational leaders:3M: The product system is very comprehensive, such as a series that combines PI film and foam.Rogers: Leading in technology for high-temperature foam and composite materials.Tesa, Nitto, Saint Gobain, and others all have corresponding high-performance composite product lines.Excellent domestic suppliers:With the development of new energy and high-end manufacturing, many domestic enterprises are able to produce high-quality PI composite tapes/gaskets, especially in the field of new energy vehicle battery pack applications, where the process of localization substitution is fast.summaryPolyimide composite tape is a smart crystallization of materials engineering.

Green high-temperature PET tape.This is a very common and widely used high-performance industrial tape. Its' green 'is usually the result of dyes or coatings, used for product identification, shading, or to meet the visual requirements of specific industries such as electrical.Interpretation of Core StructureSubstrate: Polyethylene terephthalate film, abbreviated as PET film (also known as polyester film). This is a high-strength, dimensionally stable, and transparent engineering plastic film.Color: Green. This is achieved by adding green dye to PET film or adding colorants to adhesive. This gives it light blocking and recognition properties.Adhesive: Typically, modified acrylic pressure-sensitive adhesive or silicone pressure-sensitive adhesive with excellent high temperature resistance is used.Release paper/film: protective adhesive layer, easy to use.Key performance characteristicsExcellent temperature resistance:According to different adhesives, the long-term temperature resistance range is usually between 130 ° C and 180 ° C.Can withstand higher peak temperatures in the short term (such as over 200 ° C for several minutes).Excellent electrical insulation:PET substrate itself is an excellent insulation material, and adhesive tape is widely used for insulation wrapping and protection of various electronic components.Excellent mechanical performance:High strength, tear resistance, puncture resistance, thin thickness but high strength.Excellent dimensional stability, not easily shrunk or stretched under temperature and humidity changes.Good chemical resistance:Can resist the erosion of various solvents, oils, and weak acids and bases.Color function (green):Light blocking property: It can block light of a certain wavelength and is used for electronic components (such as LEDs, photosensitive devices) or optical applications that require light avoidance.Identification and Marking: Green color facilitates area identification, polarity differentiation (such as distinguishing negative poles on capacitors), or quality traceability in production lines or products.Aesthetics and uniformity: making the final product look more uniform and professional.Main application areasElectronic and electrical industry (core application)Insulation wrapping: Insulate and protect transformers, inductors, motors, wiring harnesses, ponent fixation and reinforcement: fixing capacitors, resistors and other components, or used for PCB reinforcement (such as gold finger reinforcement for flexible circuit boards FPC).Color identification: For example, the negative electrode wrapping identification used for aluminum electrolytic capacitors.Light shielding application: Wrap around sensors or components that require protection from light interference.High temperature process shieldingUsed for shielding and protecting gold fingers, connectors, or through holes on PCB boards that do not require soldering during wave soldering or reflow soldering processes. This is a very important application of it.Due to the sharp edges of PET tape, it can effectively prevent solder from climbing and can usually be removed relatively cleanly after high temperatures.Packaging and sealingUsed for sealing cardboard boxes and boxes that require certain strength and temperature resistance.General industrial fixation and protectionTemporarily or permanently fix components in high temperature or environments that require reliable fixation.How to choose and useKey points for selection:Confirm temperature and duration: The nominal temperature resistance level of the selected tape must be higher than the maximum temperature of your process. For example, if the peak temperature of reflow soldering is about 250 ° C (short-term), a specially optimized ultra-high temperature PET tape should be selected.Confirm bonding surface: Different adhesives have different adhesiveness to different materials (such as plastic, metal, glass). For low surface energy materials such as PP and PTFE, special formulations of adhesive need to be selected.Do you need residue free adhesiveFor applications that require removal such as solder masking, it is essential to choose "high-temperature residue free" PET tape.For permanent insulation wrapping, long-term bonding reliability is more important.Pay attention to thickness and specifications: Common thicknesses include 0.055mm, 0.075mm, 0.10mm, etc. Thicker provides stronger mechanical protection, but slightly less flexibility. The width ranges from 2mm to tens of millimeters.Using best practices:Surface cleaning: Ensure that the surface being pasted is clean, dry, oil-free, and dust-free.Application technique: Apply smoothly, use a scraper or hard card to compact, especially the edges, to avoid bubbles and warping.Removal timing (for masking applications):Post weld cooling: After welding, wait for the PCB board to completely cool to room temperature before peeling off the tape. Hot tearing can easily lead to adhesive residue or tape breakage.Peel angle: Slowly and uniformly peel back at a 180 degree angle.Test verification: Before large-scale use, it is necessary to conduct small-scale process testing to verify its temperature resistance, shielding effect, and removal parison with related tapesCharacteristics: Green high-temperature PET tape, polyimide tape (brown/gold), high-temperature decorative paper tapeSubstrate PET Polyester Film Polyimide Film (PI) Special Wrinkle PaperMaximum temperature resistance ★★★☆ (lasting around 180 ° C) * (lasting above 260 ° C) ★★☆ (lasting around 150-180 ° C)Strength/Tear Resistance *☆ (Extremely High) * (Extremely High) ★☆☆ (Low, Easy to Tear)Electrical Performance ★★★★ (Excellent) * (Excellent) ★★☆ (General, susceptible to moisture)Color/blackout available in color (such as green), usually amber/transparent, usually natural/lightMain applications include electronic insulation, solder shielding, identification of ultra-high temperature solder shielding, flexible circuits, strong insulation spraying, and low-temperature shielding in baking paintMedium to high costIn summary, green high-temperature PET tape is a versatile tape that achieves an excellent balance between strength, temperature resistance, insulation, and cost in electronic manufacturing and general industry. Its green color is not only for aesthetics, but also for shading and recognition functions.High-temperature residue-free masking tape
This is an industrial tape designed specifically for clean peeling after high-temperature processes without leaving any residual adhesive traces. It perfectly balances "strong viscosity at high temperatures" and "clean removal after cooling", and is a key consumable in precision manufacturing and surface treatment.Core design objectives and principlesObjective: To firmly protect the shaded area during high-temperature processes such as spraying, baking, and electroplating. After the process is completed, it can be easily and completely peeled off without leaving any adhesive stains or damage on the protected precision machined surfaces such as high gloss paint, glass, and mirror metal.Principle: Its adhesive is a cross-linked pressure-sensitive adhesive with a special formula (usually modified acrylic or organic silicone). When heated, the adhesive layer will further crosslink and solidify, providing stronger temperature resistance and permeability resistance; After cooling to room temperature, the cohesive strength of the adhesive layer decreases, making it flexible and easy to tear, thus achieving clean peeling.Key performance characteristicsNon residual adhesive properties: the most essential characteristic. After peeling, the surface is clean without the need for additional cleaning, saving time and avoiding damage to the workpiece.Excellent high temperature resistance: Depending on the grade, it can withstand sustained high temperatures ranging from 120 ° C to 230 ° C (for 30 minutes to several hours), with higher short-term peak temperature tolerance.Resistance to chemical penetration and solvents: It can effectively resist the penetration of paint, coatings, powders, solvents, etc., ensuring clear and sharp masking edges without "paint penetration" burrs.Good flexibility: The substrate is soft and can adhere well to complex surfaces and corners.Stable adhesive force: The adhesive force remains stable during high temperature processes and will not become excessively viscous or lose its stickiness due to heat, resulting in detachment.Aging resistance: Stable performance within a certain storage period.Main Structure and TypesThe performance of masking tape is mainly determined by the substrate and adhesive.Type (by substrate) Characteristics Typical temperature resistance range Common applicationsThe base material of high-temperature textured paper tape is special wrinkled paper, which is easy to tear by hand, has low cost, and good flexibility. 120 ° C-150 ° C (medium temperature) automotive repair paint, ordinary industrial spray painting, wood spray painting masking.The substrate of high-temperature PET film tape is polyester film, which has high strength, puncture resistance, tear resistance, and excellent edge impermeability. 150 ° C-200 ° C (medium high temperature) precision electronic component spraying, anodizing shielding, glass deep processing, high requirement powder spraying.High temperature paper/cloth based adhesive tape is made of paper or cotton cloth, with extremely high strength and tear resistance, suitable for heavy-duty environments. High temperature baking paint and sandblasting shielding for heavy machinery, ships, and steel structures at temperatures ranging from 150 ° C to 230 ° C.High temperature polyimide tape (gold finger tape) is based on amber colored polyimide film (PI), which has extremely high temperature resistance and good electrical performance. Wave soldering, reflow soldering, SMT over furnace shielding, and high-temperature electrical insulation at temperatures above 260 ° C.Core tip: All types of tape must be paired with specialized high-temperature residue free adhesive to achieve the final effect. Different substrates determine the mechanical properties and applicable scenarios of the adhesive tape.Core application areasSurface spraying and painting:Automotive industry: precise masking of window frames, decorative strips, headlights, and other parts for vehicle spraying and repair paint.Electronic products: Spray shielding for consumer electronic products such as mobile phone cases and laptop cases.Industrial manufacturing: baking paint and powder coating for household appliances, instruments, and metal components.Electroplating and anodizing:Cover the local area to prevent it from being coated with metal or forming an oxide layer. Require the tape to be absolutely resistant to electrolyte penetration.Glass and mirror processing:Protect glass edges and mirrors from scratches or contamination during cutting, transportation, and deep processing.Electronic Manufacturing (SMT/Wave Soldering):Use polyimide tape to cover the gold fingers or specific areas to prevent them from being soaked by solder.Heat treatment and high-temperature curing:Protect threads, precision hole positions, etc. during high-temperature curing process.How to choose and use correctly?Choose the three-step method:Determining process temperature and time: These are the most important parameters. You must choose a tape with a nominal temperature resistance value higher than the maximum temperature of your process, and consider the total heating time.Confirm the material of the surface to be pasted: high gloss paint, glass, plastic, or rough metal? Different surface energies require the selection of appropriate adhesive tape. For extremely sensitive surfaces (such as new car paint), ultra-low viscosity versions should be selected.Consider the environment and medium: are there any solvents or acid-base liquids in contact? Do you need UV protection? Based on this, select the tolerance of the tape substrate and adhesive.Using best practices:Surface cleaning: Like Teflon tape, cleaning is key. Wipe with isopropanol (IPA) and stick.Pasting technique: Paste smoothly in one direction at room temperature, use a scraper or fingers to compact, especially at the edges, to ensure sealing.Peel off after baking:Best timing: Peel off immediately when the workpiece has cooled to room temperature or slightly residual temperature (such as below 40 ° C). At this point, peeling is the easiest and cleanest.Peel angle: Peel back slowly and evenly at a 180 degree angle, avoiding rapid pulling.Avoid hot tearing: Do not forcefully tear off at high temperatures, as the adhesive layer is still in a "molten" and viscous state, which can easily break and leave adhesive.Difference from Teflon glass cloth tapeCharacteristics: High temperature, residue free masking tape, Teflon glass cloth tapeThe core purpose is temporary protection and shielding, requiring the clean removal of permanent/semi permanent functional coverings, providing non stick, wear-resistant and other characteristicsThe temperature resistance range is usually ≤ 230 ° C (excluding polyimide), and can be continuously used up to 260 ° C or aboveThe surface characteristics are usually paper or film, with no special surface functions. It has the non stick, low friction, and chemical resistant surface of TeflonRemovable design allows for easy and residue free removal without difficulty, usually leaving adhesive or designed for long-term useTypical applications include spray masking, electroplating masking, heat sealing machine wrapping, anti sticking conveyor belts, and high-temperature insulation protectionSummary:If you need to tear off the tape after high-temperature processing without leaving any traces, choose high-temperature residue free masking tape.If you need the tape to withstand high temperatures for a long time and provide special features such as non stick and wear-resistant, then choose PTFE glass cloth tape.I hope this detailed analysis can help you make accurate choices and applications. If you can provide specific usage scenarios (such as what workpiece, what process, and what temperature), I can give you more specific model recommendations.
