2025-12-24High-quality PET substrate double-sided tape
High quality PET double-sided tape is a product made of high-strength, ultra-thin polyester film as the intermediate substrate, coated with high-performance pressure-sensitive adhesive (acrylic or silicone) on both sides, and protected by double-sided release material. The core of its design is to achieve ultra-thin, flat, high insulation, and dimensional stability while providing strong adhesion.Why choose PET substrate (compared to foam substrate)?Characteristics: PET substrate double-sided tape, foam substrate double-sided tapeUltra thin thickness (0.025mm -0.2mm), takes up less space and is thicker (0.1mm -3.0mm+), with filling propertiesHigh hardness/modulus, strong rigidity, creep resistance, low displacement, soft, with cushioning and shock absorption propertiesAdhesive properties surface contact, providing high and uniform shear strength surface contact, but prone to deformation under stressMain applications include precision structure fixation, conductive shielding, insulation sheet bonding and filling gaps, buffer sealing, shock absorption, and covering uneven surfacesExcellent processability, easy to die cut into complex and precise shapes, but the edges may produce foam debrisSix key characteristics of high-quality PET double-sided tapeUltra thin and high flatness:The substrate thickness can be as thin as 0.025mm, and the total thickness can be controlled at around 0.05mm, with almost no increase in assembly thickness. It is suitable for situations with extremely limited space (such as inside smartphones and ultra-thin display screen modules).Extremely high flatness, able to perfectly adhere to smooth surfaces without warping.Extremely high tensile strength and dimensional stability:The tensile strength of PET substrate is extremely high, and it hardly expands or deforms in hot and humid environments, ensuring the long-term alignment accuracy of adhesive components.Good creep resistance, less prone to displacement under long-term stress.Excellent electrical performance:It is an excellent insulator and is commonly used for bonding and fixing FPC (flexible circuit board), battery insulation sheets, and graphite heat sinks.By coating conductive adhesive (such as conductive carbon paste, silver paste), conductive double-sided tape can be made for grounding, electromagnetic shielding (EMI), etc.Powerful adhesive performance and durability:High quality acrylic adhesive (the most common) is selected to provide high initial adhesion and long-term adhesion to a wide range of materials such as metals (stainless steel, aluminum), glass, plastics (PC, ABS, PMMA), rubber, etc.The temperature resistance is usually between -20 ° C and 120 ° C, and special models can reach up to 150 ° C.Solvent resistant, UV resistant, anti-aging.Clean processing and removal performance:The release force is precisely controlled, making it easy for die-cutting, waste removal, and automated mounting.Reasonably designed adhesive tape can be removed relatively cleanly through professional methods or specific conditions (such as heating) when maintenance is needed, reducing residual adhesive.Diversified adhesive options:Universal acrylic adhesive: with the best comprehensive performance, balancing adhesion and weather resistance.Low VOC/low odor acrylic adhesive: used in sensitive environments such as optics and car interiors.High temperature resistant acrylic adhesive: used in occasions with heating anic silicone: resistant to extreme high and low temperatures (-40 ° C to 200 ° C+), but has weak adhesion to certain plastics and is expensive.Main application areasConsumer Electronics:Structural fixation: phone/tablet frame and battery FPC、 Fixing of sub boards and small components.Functional component pasting: pasting graphite heat sink, thermal conductive silicone sheet, metal shielding cover, touch screen, fingerprint module.Insulation protection: fixing of battery insulation sheets and circuit board insulation clamps.Optics and Display:Temporary or permanent fixation of lens modules, small cameras, and optical ponent bonding in display module (LCD/OLED).Automotive Electronics:The bonding of car display screens, sensors, and control panels requires high temperature and humidity resistance.Industrial manufacturing:Paste nameplates and signs.Assembly of precision hardware and plastic components.Fixing of SMT steel mesh (red glue/solder paste sheet).How to choose "high-quality" products? ——Key parameters and considerationsThickness (one of the most critical parameters):Substrate thickness: determines the rigidity, tensile strength, and insulation strength of the tape.Adhesive layer thickness: affects the ability to fill small unevenness and adhesive strength.Total thickness: Choose according to your design space and filling requirements. For example, 0.05mm PET+0.03mm adhesive layer x2=0.11mm total thickness.Adhesive performance:Initial adhesion: the ability to quickly adhere.Peel force (usually measured at 180 ° or 90 °): The force required to tear the tape off the surface, measured in N/inch or N/cm.Adhesive force (shear creep): The ability to resist displacement under long-term loading, measured in hours.Shear strength: One of the most important indicators, it represents the ability of the tape to resist parallel forces, measured in N/cm ². The shear strength of PET double-sided adhesive is usually very high.Release system:Double silicon release paper: Both sides are coated with silicon release paper, which is low-cost and commonly used.PET release film: flatter and more rigid, suitable for ultra-thin tape and high-speed automated mounting.Lightweight release: One side has light release force, while the other side is heavy, making it easy to manually take and attach, and preventing sticking together.Environmental tolerance:Confirm the requirements for temperature resistance, moisture resistance, and chemical resistance (such as plasticizer resistance) based on the application environment.Certification and Compliance:UL certification (insulation materials), RoHS, REACH (no harmful substances) are crucial for exporting electronic and electrical products.Representative brand and product series reference3M: Industry benchmark, with an extremely rich product line. Such as 3M 467MP/468MP (super adhesive, universal type), 3M 300LSE (low VOC, optical grade), 3M 9703 (conductive type).Tesa: European quality, strong in the automotive and electronics fields. Such as the tesa 696xx series.Nitto: Japanese Seiko, skilled in ultra-thin and optical applications. Like the Nitto 5000NS series.Teraoka: Renowned in the die-cutting industry.Domestic high-quality brands such as Jinghua, Siwei, Yongle, etc. have rapidly improved their quality in recent years, with high cost-effectiveness, and can meet most industrial needs.Usage and Testing SuggestionsSurface treatment: A clean, dry, and oil-free surface of the adhesive is a prerequisite for ensuring the best bonding effect.Pressure and time: Apply sufficient roller pressure after pasting and ensure sufficient initial curing time (usually 24-72 hours to achieve maximum adhesion).It is necessary to conduct sample testing: After selecting the supplier and model, comprehensive machine testing must be carried out to simulate actual working conditions (temperature, humidity, load, time) and verify their long-term reliability.Summary: High quality PET substrate double-sided tape is the "invisible welding point" of precision engineering. When making a choice, it should be systematically considered from the four dimensions of "thickness strength environment process", and fully communicated with the supplier's technical personnel to lock in the most suitable one for your product through actual testing.High-temperature resistant green PET insulation tape
"High-temperature resistant green PET insulation tape"As the name suggests, this tape is specifically designed for scenarios where reliable electrical insulation is required in high-temperature environments. 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. The higher the value, the stronger the insulation capability.Temperature resistance level:Long-term use temperature (e.g. Class B: 130℃, Class F: 155℃, Class H: 180℃).Short-term overload temperature.Thickness: It affects the insulation effect and flexibility.Adhesion: Ensure a firm adhesion to wire insulation, enameled wire, or metal surfaces.Flame retardancy: Although not emphasized in the name, high-quality electrical insulating tape typically requires a UL 94 V-0 flame retardant rating, which is crucial for safety.Certification: Whether there are safety and environmental certifications such as UL, CSA, RoHS, etc.For a detailed comparison with related products to help you distinguish clearly, please refer to the table below:Characteristics High-temperature resistant green PET insulation tape Green PET high-temperature resistant silicone tape Polyimide (gold finger) high-temperature tape High-temperature resistant glass cloth tape Core demands Electrical insulation + temperature resistance + identification Temperature resistance + fixation/shielding + identification Ultra-high temperature residue-free shielding Flame retardant + mechanical protection + insulation Key indicators Dielectric strength (kV/mm) Temperature resistance, adhesive strength Temperature resistance, residue-free property Flame retardant grade, tensile strength Typical adhesive systems High-temperature resistant acrylic adhesive or silicone adhesive Primarily silicone adhesive Special acrylic adhesive Silicone or flame retardant acrylic adhesive Main substrates PET film PET film Polyimide film (PI) Glass fiber cloth Hand feel/strength Stiff and tensile Stiff and tensile Extremely thin and flexible Soft and extremely wear-resistant and tear-resistant Typical applications Motor insulation, electronic component insulation wrapping High-temperature shielding and high-temperature fixation in SMT PCB reflow soldering shielding Wire harness bundling, pipeline insulation and fire protection Cost Medium On the higher side of medium Very high Medium Summary and decision-making suggestions In simple terms:If your primary need is electrical insulation, and the environment has a certain temperature, and you also need green as a marking, then "high temperature resistant green PET insulation tape" is your direct choice.If the temperature is extremely high (>180℃) and precise masking is required, polyimide tape should be chosen.If you require extremely strong mechanical protection, wear resistance, and flame retardancy, you should choose glass cloth tape.If both products have high temperature and green labeling, but without stringent official certification requirements for insulation properties, they may be interchangeable. However, products labeled as "insulating tape" typically offer greater assurance in terms of dielectric strength.Finally, please ensure to make your selection based on your actual application voltage level, operating temperature, and specific scenario. Checking the "dielectric strength" and "temperature class" in the product specification is a crucial step in model selection.Teflon double-sided tape
Teflon double-sided tape. This is a very unique and high-performance industrial adhesive material that combines the excellent surface properties and double-sided bonding function of polytetrafluoroethylene (PTFE).1、 Core Structure and Material AnalysisThis type of tape can be seen as a "sandwich" structure:Core substrate (intermediate layer): Pure PTFE film or glass fiber reinforced PTFE composite material.The characteristics of Teflon: This is the core value of adhesive tape.Extremely low surface energy: "Non sticky" is extremely strong, and almost all substances are difficult to firmly adhere to its surface.Excellent temperature resistance: The long-term working temperature range is -200 ° C to+260 ° C, and the short-term can reach over 300 ° C.Excellent chemical inertness: resistant to corrosion from almost all strong acids, alkalis, and organic solvents.Excellent insulation: high dielectric strength.Extremely low friction coefficient: very lubricating.Two side adhesive layer: a special pressure-sensitive adhesive coated on both sides of the PTFE substrate. This is a technical key, as conventional adhesives are difficult to adhere to Teflon.Adhesive type: usually high temperature resistant silicone pressure-sensitive adhesive or fluorosilicone pressure-sensitive adhesive. They have undergone special treatment to form effective adhesion with PTFE surfaces, while also possessing excellent temperature resistance and chemical stability on their own.Release layer: Protect the release paper or release film on both sides of the adhesive surface.2、 Core features and advantagesCombining "non stickiness" and "strong stickiness": this is its greatest contradictory charm. The tape itself can strongly adhere to the surfaces of two objects (such as machine tables and molds), while its PTFE working surface provides long-lasting non stick and easy to clean properties.Ultra wide temperature resistance range: able to withstand extreme temperature environments ranging from deep cold to extremely high heat, with stable performance.Excellent chemical resistance: suitable for harsh environments with chemical splashes or repeated wiping with cleaning agents.Excellent electrical performance: suitable for electrical applications that require insulation and high temperature resistance.Wear resistance and durability: Glass fiber reinforced PTFE substrate has high mechanical strength and service life.3、 Main application areas (solving specific problems)Teflon double-sided tape is commonly used in special scenarios where both secure installation and non stick, high-temperature resistant, or easy to clean surface properties are required.Heat sealing, welding and packaging machinery:Sealing machine heat sealing tape: glued to the heating plate, using its non adhesiveness to prevent packaging materials (such as plastic bags) from melting and sticking to the machine, is the most classic application.Plastic welding equipment: a tool surface used for ultrasonic welding and hot plate welding.Mold and composite material processing:Release layer: affixed to the surface of the mold as a permanent or easily replaceable release layer, used for molding composite materials such as epoxy resin and polyurethane, greatly facilitating demolding.Protective layer: protects expensive mold surfaces from scratches and chemical corrosion.Food and chemical equipment:Stick to the inner walls of conveyor belts, workbenches, or hoppers to prevent sugar, grease, chemical raw materials, etc. from adhering and facilitate cleaning.Sealing gasket for reactor or pipeline interface (suitable adhesive type should be selected).Electronic and electrical manufacturing:As an insulating and non stick cushion layer in high-frequency welding (such as inductor coils) or high-temperature welding fixtures.Special components that require insulation and chemical resistance for fixation.Laboratory and General Industry:Stick it on the surface of the laboratory and workbench to create a corrosion-resistant and easy to clean workspace.The hot bed surface film of the 3D printer provides good adhesion and is easy to remove the model.4、 Key selection parametersSubstrate type:Pure PTFE film: softer and best non stick.Fiberglass reinforced PTFE: more rigid, wear-resistant, tensile resistant, dimensionally stable, and has high mechanical strength, making it a more common choice.Thickness: The total thickness (including adhesive layer) is usually between 0.08mm and 0.3mm. The thicker, the better the filling gap and buffering ability.Adhesive type:Silicone pressure-sensitive adhesive: the most common, with a wide range of high and low temperature resistance and good flexibility.Fluorosilicone pressure-sensitive adhesive: It has better chemical resistance and high temperature resistance, especially in non-polar solvents, and is more expensive.Temperature resistance level: Clearly define the long-term operating temperature and short-term peak temperature.Adhesive force: Confirm its peel strength to the target surface (such as stainless steel, aluminum, plastic).Certification: For food or medical related applications, it is necessary to confirm whether there are FDA, LFGB and other food contact safety certifications.5、 Common brands and precautions in the marketFamous brand:3M: For example, 3M 5490, 3M 5590H and other series are industry high standards.Saint Gobain, Desha, Nitto Denko, and others also have corresponding product lines.Domestic/professional brands: There are also multiple manufacturers in China producing products with high cost-effectiveness, and their performance needs to be carefully verified.Precautions for use:Surface treatment: Before pasting, ensure that the adhered surface is absolutely clean, dry, and free of grease, otherwise it will seriously affect the bonding effect and durability.Apply sufficient pressure: After pasting, use a roller or fixture to apply solid and uniform pressure to ensure sufficient contact.Bonding temperature: It is recommended to stick some products at room temperature (above 21 ° C) for optimal initial adhesion.Maintenance time: After bonding, it takes 24-72 hours to reach the maximum bonding force and avoid bearing the maximum load during this period.Removal: Designed for permanent or semi permanent bonding, removal is very difficult and often results in adhesive residue or damage to the substrate.summaryTeflon double-sided tape is an engineering material designed to solve special contradictions under extreme working conditions: it provides a "sticky" body and a "non stick" working surface.When your application scenario requires both:Firmly install a component onto the equipmentAnd the surface of this component must be resistant to high temperatures, anti sticking, anti chemical corrosion, and easy to cleanGlass cloth double-sided tape

This performance enables it to work stably in extreme environments such as ovens, high-temperature spray lines, or inside motors.Extremely high mechanical strength: The glass fiber cloth substrate endows the tape with astonishing tensile strength, making it very suitable for scenarios that require secure bundling or use under high stress, such as wrapping and fixing coils.Excellent electrical insulation performance: This type of tape usually meets the H-level insulation standard and has a certain voltage resistance ability (such as 3kV), which can be effectively used for insulation protection of electrical equipment such as transformers and motors.Clean removal characteristics: High quality silicone pressure-sensitive adhesive can still be cleanly peeled off from the adhered surface after high-temperature treatment, leaving almost no residue. This is crucial for processes that require temporary masking, such as high-temperature sandblasting and baking paint.Typical application scenariosWith the above characteristics, this tape is widely used in:Electronics and Electrical Industry: Used for H-grade heat-resistant insulation binding, such as insulation of dry-type transformer leads, packaging and fixing of motor coils, insulation wrapping of lithium batteries, etc.High temperature manufacturing process: As a high-temperature masking tape, it is used for wave soldering protection, high-temperature sandblasting protection, ceramic component fixation, and other scenarios on printed circuit boards (PCBs).Industrial and special fields: Used for wire harness winding, high-temperature pipeline sealing, and strengthening insulation and mechanical protection in heavy load environments in industries such as aerospace, automotive manufacturing, and military.How to choose?When choosing a specific product, you can pay attention to the following key points:Confirm temperature resistance level: Confirm whether your process environment temperature remains stable within a certain range for a long time or only has short-term high temperature. Silicone tape usually has higher temperature resistance.Clear adhesive system: The mainstream choice is silicone pressure-sensitive adhesive because it has higher temperature resistance and does not leave any residue. If the temperature resistance requirement is not high (such as below 130 ℃), there are also lower cost acrylic adhesive systems to choose from.Reference benchmark models: Many high-quality domestic products can completely replace internationally renowned brands in terms of performance, such as 3M's 69 #, 361 #, or TESA's 4618 #. If you have used these models before, you can easily find alternativesEpoxy thermoplastic composite adhesive film
Epoxy thermoplastic composite film is a high-performance adhesive material, whose core feature is to combine thermosetting epoxy resin with thermoplastic resin (such as polysulfone, nylon, etc.), usually in the form of a thin film, mainly used for bonding and manufacturing composite materials.To help you understand more clearly, we can look at the following aspects:1. What is it? ——A type of adhesive film that combines rigidity and flexibilityEpoxy resin itself is hard and heat-resistant, but relatively brittle; And thermoplastic resin is very flexible. The combination of the two is to allow epoxy resin to retain its high strength and heat resistance advantages while increasing toughness through thermoplastic resin, solving its "brittle" weakness.Form: It usually exists in the form of a solvent-free film, with very precise thickness and resin content, making it easy to operate and process control.Curing: When in use, it requires a chemical reaction at a certain temperature to cure (crosslink) and ultimately form a strong bond.2. Core advantage: Why add thermoplastic resin?Adding thermoplastic resins (such as polyethersulfone, nylon, etc.) to epoxy resins for modification mainly brings three major benefits:Significantly improving resilience: This is the primary objective. Research has shown that adding 20% thermoplastic resin can increase the impact strength of composite materials by 154% and the bending strength by about 50%.Ensure high strength: While increasing toughness, it can still maintain the excellent cohesive strength and heat resistance of epoxy resin. For example, a patented product has been toughened with thermoplastic resin, increasing its temperature resistance level to 175 ℃ and achieving a glass transition temperature (Tg) of 190 ℃.Good process performance: The adhesive film is easy to lay and suitable for bonding large and complex structural components. There are almost no volatiles during curing, ensuring the density of the adhesive layer.3. Main application scenariosDue to its excellent comprehensive performance, this adhesive film is mainly used in high-end fields:Aerospace: This is the most important application field. Used for manufacturing and bonding aircraft structural components (such as wings, fuselage), radar antenna covers, engine nacelles, etc., it needs to withstand extremely high stress and temperature changes.Rail transit: used for the manufacturing and assembly of lightweight components for trains, such as bonding carbon fiber bodies and interior parts, to meet the weight reduction and strength requirements of high-speed trains.Sports equipment and electronics: also used for manufacturing high-performance sports equipment (such as tennis rackets, bicycle frames), as well as for bonding electronic components that require high reliability.4. Typical product casesTo give you a more intuitive understanding, here are two typical products on the market:Product Name Key Features Typical Application SourcesThe Henkel LOCTITE EA 9658 is designed specifically for engine nacelles, with three times the toughness of similar products, and can be used for a long time at 177 ℃ (tested for 6000 hours).

Working temperature range -55 ℃ to 149 ℃, can be co cured with prepreg. Aerospace (composite material surfaces requiring lightning protection)summarySimply put, "epoxy thermoplastic composite film" is a high-performance film adhesive made by combining strong and tough epoxy resin with flexible thermoplastic resin. It not only retains the heat resistance and high strength of epoxy resin, but also solves its brittleness problem through thermoplastic resin, making it an indispensable key material in high-end manufacturing industries such as aerospace.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?Teflon double-sided tape

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.Golden Finger Tea Color High Temperature Resistant Insulation Tape
