It possesses the following composite characteristics:Excellent electrical insulation (core):The PET substrate itself possesses excellent insulation properties, and when combined with specialized insulating glue, it exhibits high dielectric strength, effectively preventing current leakage, short circuits, and breakdown. It is suitable for insulation wrapping in medium and low voltage electrical environments.Excellent high temperature resistance:The long-term temperature tolerance range is typically between 130℃ and 180℃, depending on the glue formula (which may be high-temperature resistant acrylic glue or silicone glue). It can adapt to the temperature rise environment of heating components such as motors and transformers.Physical properties of PET substrate:High strength: Resistant to tension and tearing, providing excellent mechanical protection.Dimensional stability: It is not prone to shrinkage and deformation when heated, ensuring the stability of the insulation layer.Chemical resistance and moisture resistance: It exhibits good resistance to most solvents, oils, and greases, as well as humid environments.Smooth surface: easy to clean, not prone to dust accumulation.The function of the green appearance:Phase identification: In electrical engineering, green is commonly used to identify grounding wires or specific phases (note: electrical color standards may vary across different countries/regions, with yellow-green being the standard for grounding wires in China).Safety warning: It serves as a prominent marker in equipment or wiring harnesses.Grade differentiation: Used to distinguish lines of different voltage levels or functions in complex wiring harnesses.Due to its multifunctional properties of insulation, temperature resistance, and identification, the core application field is commonly found in:Motor and transformer manufacturing: interlayer insulation of coil windings, bundling, and insulation protection of outgoing line parts.Household appliances: Cable insulation and fixation for heating components (such as those inside electric ovens and hair dryers).Automotive electronics and wiring harness: Insulation wrapping and identification of cables in high-temperature areas within the engine compartment.Power supply and inverter: Insulation wrapping and identification of internal power components and busbars.Industrial equipment: Repair or reinforcement of wire insulation at high-temperature points within switchboards and control cabinets.When purchasing key indicators, please be sure to verify the following parameters, which are usually clearly listed in the product specification:Dielectric strength (breakdown voltage): This is the most crucial indicator for measuring insulation performance, with units of kV/mm or V/mil.

Purpose 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.

High temperature textured paper tape

Thermal anti adhesive protective film

Thermal anti adhesive protective film is a functional thin film material that can significantly reduce or even eliminate its viscosity by heating, thereby achieving no residual adhesive and no damage peeling.Its core lies in a "thermal response" mechanism. Simply put, before heating, it can provide sufficient adhesion to fix and protect the workpiece, just like a regular protective film; After the process is completed, simply heat it to a specific temperature, and the viscosity will sharply decrease (from a few hundred grams of adhesive force to negligible), making it easy and clean to peel off.1、 Core principle: Two mainstream technological routesThere are two main technologies for achieving this "thermal anti sticking" effect, which are currently applied in the market:Foaming type: using microsphere expansion to break the bondThe adhesive layer of this protective film is dispersed with tiny thermal expansion microspheres. After heating, the microspheres rapidly expand and increase in volume, disrupting the continuity of the adhesive layer and causing a sharp decrease in the contact area between the adhesive layer and the surface of the object being adhered, resulting in loss of adhesion.Key indicators: Heating expansion to lose viscosity usually takes only 10 seconds to 5 minutes, depending on the heating temperature and the formula design of the protective film.Peeling effect: It can achieve "automatic peeling", that is, after heating, the adhesive film will automatically arch or fall off from the surface of the workpiece due to the loss of viscosity, greatly improving efficiency.Material phase change type: using special polymer materialsThis is a relatively new technology that does not use foaming agents. It is achieved by adding a specific proportion of liquid crystal material (such as 5% -15% of the total weight) to the acrylic resin adhesive chanism of action: At room temperature, the liquid crystal molecules in the adhesive layer maintain an ordered state, providing high viscosity; After heating, the liquid crystal molecular structure undergoes a thermally induced phase transition, breaking the molecular arrangement of the adhesive and resulting in a significant decrease in its macroscopic adhesion.Advantage: This design can avoid the residual glue problem that may exist in traditional heat reducing films and improve the reliability of peeling.2、 Key characteristics and important parametersWhen choosing a thermal anti adhesive protective film, the main focus is on the following core parameters:Typical numerical range of parameters/explanation of impact and selection suggestionsPeel off temperature low temperature: 90-100 ° CMedium temperature: 120-130 ° CHigh temperature: The core indicator selected is 140-180 ° C. It must be higher than the process temperature during processing, but it cannot be too high to avoid damaging the workpiece that is not heat-resistant.Initial viscosity low viscosity (~200g/25mm)Medium viscosity (~400g/25mm)High viscosity (~700-1500g/25mm) is selected based on the weight of the workpiece and fixing requirements. Excessive adhesion may cause difficulty in peeling off after processing, while insufficient adhesion may prevent firm fixation.After heating, the viscosity usually drops to<10g/25mm, or even lower to 0.02N/20mm, which is the key to evaluating the difficulty of peeling. The smaller the value, the easier the peeling and the lower the risk of damage to the workpiece.The common substrate and thickness are PET (polyester film), as well as high-temperature resistant materials such as PI. The total thickness is usually between 50 μ m and 115 μ m. PET has good comprehensive performance and low cost; PI has better heat resistance. Thickness affects flexibility and strength, and needs to be adapted to the surface and processing method of the workpiece.The core advantage of this product is to have no residual adhesive after peeling, but the compatibility between the product and specific materials needs to be verified in application.3、 Main application areasThanks to its heating and anti sticking properties, thermal anti sticking protective films are widely used in precision manufacturing fields that require temporary fixation and protection, especially in the electronics industry:Semiconductors and Microelectronics: Used for fixing and protecting the backside grinding and cutting process of chip wafers. After cutting, heating can easily pick up individual chips (grains) from the tape without damaging the chips or leaving adhesive residue.Passive component manufacturing: used for cutting, positioning, and handling in the manufacturing process of small components such as MLCC (Multi Layer Ceramic Capacitor) and MLCI (Chip Inductor).Optoelectronics and flat panel displays: used for protection during the thinning, grinding, and polishing processes of LCD/TP touch panel glass.New material processing: used as a temporary carrier and protective layer in the transfer printing process of materials such as graphene and carbon nanotubes.Other applications: including but not limited to cutting and grinding of LED chips, precision metal component processing, ceramic substrate cutting, etc

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.

PET-based double-sided adhesive tape

Double-sided adhesive tape made of PET substrate. This is one of the most core and widely used categories of industrial tapes, and can be called the "universal connector in the industrial field".1. Core positioning: What is PET double-sided tape?It is made of biaxially oriented polyester film as the intermediate substrate, coated with pressure-sensitive adhesive on both sides, and protected by release paper (film). Essentially, it is a high-performance thin adhesive sheet.Keywords: strength, stability, insulation, lightness, multi-purpose.II. Why choose PET double-sided tape? Five core advantagesAdvantages Specific description Brought value1. Excellent dimensional stability: Minimally affected by temperature/humidity, with a thermal shrinkage rate of <1% (typically within 0.5%), ensuring no warping or displacement after precise fitting. It is the first choice for screen fitting and precision electronics.2. Excellent mechanical properties: Resistant to stretching, tearing, and puncturing, with high strength. Capable of withstanding significant stress, used for structural fixation and reinforcement.3. Excellent electrical insulation properties: PET itself is an excellent insulating material with high dielectric strength. It is widely used for insulation, fixation, and protection of electronic components.4. Excellent processing adaptability: Easy to die-cut, punch, and slit, suitable for high-speed automated production. High production efficiency, capable of producing any complex shape.5. Balance of performance and cost: It offers the highest comprehensive cost-performance ratio among acrylic tapes. It is thinner and stiffer than foam tape, and less expensive than PI tape, making it the most popular general-purpose choice.III. In-depth Analysis of Key Components (A Must-See for Model Selection)1. Base material: PET filmThickness: Determines the filling capacity, cushioning, and rigidity of the tape. Common thicknesses include: 0.025mm, 0.05mm, 0.075mm, 0.1mm, 0.125mm, 0.188mm, 0.25mm.Treatment: Corona or coating treatment to enhance the adhesive's adhesion.Color and translucency:Transparency: Optical applications, such as temporary fixation of display devices.White/Black: Shading, identification, decoration (such as internal cover of mobile phone, bottom layer of nameplate).Beige/Gray: General industrial use.2. Adhesive: The soul of performanceSolvent-based acrylic adhesive: The mainstream choice. High initial adhesion, high final adhesion, good temperature and weather resistance.Water-based/lotion-type acrylic adhesive: More environmentally friendly (low VOC), but slightly weaker in water resistance and high temperature resistance.Silicone pressure-sensitive adhesive: used in high-temperature scenarios (long-term exposure to 150-200°C), but with high cost and potentially poor adhesion to plastics.The core performance indicators of adhesives include: initial adhesion, peel strength, holding power, temperature resistance, and chemical resistance.3. Release material: Affects processing efficiencyMaterial: PET release film (high flatness), glassine release paper (economical).Release force: Light, medium, and heavy release, which must match the peeling capability of automatic mounting equipment.IV. Mainstream Application Scenarios and Selection GuidelinesApplication Industry Typical Use Recommended Tape Characteristics (Keywords)Consumer electronics: Mobile phones/tablets: Internal component fixation, FPC attachment, battery fixation, and decorative part fitting. Ultra-thin (0.05-0.1mm), high adhesion, good die-cutting performanceDisplay assembly: Auxiliary fixation of LCD and backlight, touch module and cover panel. High transparency, low haze, no Newton's rings, medium viscosity (easy to rework)Automotive electronics/interior decoration: fitment of in-vehicle displays, interior decoration labels, control panels, and sensor fixation. Resistance to high temperature and humidity, resistance to thermal cycling, and anti-agingLithium battery manufacturing: cell insulation, battery and housing fixation, tab protection. Insulation, flame retardant (UL94 V-0), long-term reliabilityHome appliance manufacturing: Control panel, nameplate, and internal wiring harness fixation. Temperature resistance, chemical resistance, and durable adhesionGeneral industrial use: splicing of plastic/metal/glass plates, labeling, and light-duty hook fixation. High cost-effectiveness, universal adhesion, and multiple thickness optionsV. "Four-step method" for model selection decision-makingStep 1: Determine the adherend"What am I going to glue?" (Material type: plastic, metal, glass, ceramic?)"What about surface energy?" (Difficult-to-stick plastics such as PP/PE require special adhesive systems or surface treatment)Step 2: Analyze the working environmentTemperature: Regular (-20~80°C) or High Temperature (>100°C)?Chemistry: Is there any contact with solvents, oils, or sweat?Outdoors: Is UV resistance required?Stress: Is it subjected to shear force, peeling force, or impact force?Step 3: Clarify process and appearance requirementsProcessing method: manual lamination or high-speed automatic lamination? It determines the release force and substrate stiffness.Appearance requirements: Do you need it to be transparent, white, or black? Is seamless adhesion required?Certification requirements: UL, RoHS, REACH, halogen-free, etc.Step 4: Sample testing and verification (the most crucial step!)Initial adhesion test: Does it stick instantly after being applied?Peel force test: After 24 hours or 168 hours, does the peel strength meet the standard?Aging test: After simulating high temperature and humidity, as well as cold and heat cycling, does the performance degrade?Process validation: Conduct trials on the actual production line to assess the smoothness of die-cutting, waste removal, and mounting.VI. Brand Guidelines and Procurement StrategiesBrand Tier Representative Brands Features and Purchasing SuggestionsInternational top-tier brands such as 3M, Tesa, and Nitto are performance benchmarks with the highest reliability. They are suitable for cutting-edge products with extremely high requirements and sufficient budgets (such as flagship phones and core automotive components). Procurement channels: officially authorized dealers.Domestic leaders: SOWAY, Jinghua, Yongyi, Shihua. The king of cost-effectiveness, with fast service response. Their products have covered the vast majority of mid-to-high-end applications and are the main choice for consumer electronics, home appliances, and general industrial applications. Recommended as the first choice for inquiry and sample testing.Specialized segmentation: Numerous domestic/Taiwanese brands have advantages in certain specific areas (such as special thicknesses, colors). Suitable for customers with unconventional needs.VII. Common Misconceptions and Tips to Avoid PitfallsMisconception 1: The thicker the tape, the stronger the adhesive → False! 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.
