The product specification is 33M long, and the color of the tape is usually brown or golden yellow. The commonly used widths are 10mm, 15mm, 20mm, 25mm, etc. (can be customized). High precision coating up to ± 2.5um, no scratches, wire drawing or other phenomena, good shear performance, easy to punch die cutting processing. Material parameters: Substrate thickness: 0.0125mm-0.125mm Adhesive thickness: 0.025mm-0.065mm Adhesive composition: Silicone/Acrylic Adhesive strength: 450-720g/25mm Temperature resistance -10 ℃ -300 ℃ Tensile strength 14-18kg/mm Elongation rate 55% -85% Corrosion resistance: 1.0H Electrical strength: 6000V~7200V Application area Coatings: Used as insulation paint for electromagnetic wires or as high-temperature resistant coatings. Advanced composite materials: used for aerospace, aircraft, and rocket components. It is one of the most heat-resistant structural materials. Fiber: Its elastic modulus is second only to carbon fiber, and it is used as a filtering material for high-temperature media and radioactive substances, as well as bulletproof and fireproof fabrics. Foam plastic: used as high temperature resistant and heat insulating material. Engineering plastics: There are thermosetting and thermoplastic types, and thermoplastic types can be molded by compression molding, injection molding, or transfer molding. Mainly used for self-lubricating, sealing, insulation, and structural materials. Separation membrane: used for the separation of various gases, such as hydrogen/nitrogen, nitrogen/oxygen, carbon dioxide/nitrogen, or methane, to remove moisture from air hydrocarbon feed gases and alcohols. It can also be used as a pervaporation membrane and ultrafiltration membrane. Photoresist: Some polyimides can also be used as photoresists. There are negative and positive adhesives, and the resolution can reach sub micron level. When combined with pigments or dyes, it can be used for color filter films, greatly simplifying the processing steps. Application in microelectronic devices: used as a dielectric layer for interlayer insulation, and as a buffer layer to reduce stress and improve yield. As a protective layer, it can reduce the impact of the environment on the device and also act as a shield for alpha particles, reducing or eliminating soft errors in the device. Polyimide, an alignment agent used in liquid crystal displays, plays a very important role in the materials of TN-LCD, SHN-LCD, TFT-LCD, and future ferroelectric liquid crystal displays.Electro optical materials: used as passive or active waveguide materials, optical switch materials, etc. Fluorinated polyimides are transparent in the communication wavelength range, and using polyimide as a chromophore matrix can improve the stability of the material. Moisture sensitive materials: The principle of linear expansion due to moisture absorption can be used to make humidity sensors. Storage method 1. Tape should be stored in the warehouse to avoid direct sunlight and rain; Do not come into contact with acidic, alkaline, oil or organic solvents, keep clean and dry, and keep a distance of 1 meter from the discovery device. The room temperature should be between -15 ℃ and 40 ℃. 2. The tape should be placed in rolls without folding. If stored for too long, it should be flipped once every season. 3. It is best to use a crane when loading and unloading the conveyor belt, and use rigging with crossbeams to lift it steadily to avoid damaging the edge of the belt. Do not load or unload recklessly, which may cause loose rolls and loose sleeves. 4. The type and specifications of the tape should be selected reasonably according to the usage needs and specific conditions. 5. Do not connect tapes of different varieties, specifications, strength, and fabric layers together for use. 6. It is best to use hot vulcanized rubber joints for conveyor belt joints to improve reliability and maintain high effective strength. 7. The diameter of the conveyor roller and the minimum pulley diameter of the conveyor belt should comply with relevant regulations. 8. Do not make the tape snake or crawl. Keep the rollers flexible and the tension moderate. 9. When the conveyor is equipped with baffles and cleaning devices, wear and tear on the tape should be avoided. 10. Cleanliness is a basic condition for the good operation of adhesive tape. Foreign substances can affect tape eccentricity, tension differences, and even breakage. 11. When early damage to the tape is found during use, the cause should be promptly identified and repaired to avoid adverse consequences.Quality requirementThe quality of polyimide tape is very important. Have you ever learned about the quality requirements of polyimide tape? Let me take a look.1、The adhesion of polyimide tape should be long-lasting and should not dry out after a period of time;2.

Is there any way to identify the authenticity of polyimide tape? Now, the editor will bring you a method to identify authenticity.1、Looking at the appearance, generally speaking, low-quality high-temperature tape has a slightly dull color, while high-quality gold finger high-temperature tape has a relatively good surface gloss.2. Look at the residue after ignition, bake with a lighter for 1 to 2 seconds, and then touch with your hand. The high-temperature tape of the golden finger really won’t stick to your hands.3. In actual high-temperature testing, after passing through a high temperature of 260 ° C, check for residual glue, shrinkage, and other phenomena, because the temperature resistance of real gold finger high-temperature tape is usually between 120 ° C and 260 ° C.High temperature tape: basic knowledge, common types and differences
High temperature tape usually refers to adhesive materials that can maintain good adhesion under certain high temperature environments, mainly including single-sided tape and double-sided tape. These tapes have a wide range of applications in the manufacturing of industrial electronic products, and their high temperature resistance is mainly manifested in their ability to maintain stability under temperature conditions between 120 degrees and 260 degrees. The temperature resistance of high-temperature adhesive tape mainly depends on the properties of its substrate and adhesive. Several common high-temperature adhesive tapes on the market currently include PET polyester film substrate coated acrylic adhesive, PET polyester film coated high-temperature silicone adhesive, PI polyimide film coated acrylic adhesive, PI polyimide film coated high-temperature silicone adhesive, and PTFE tape.

Its main uses are heat-resistant shielding and heat-resistant insulation for electronic boards.Due to the high thermal decomposition temperature of polyimide, it has excellent heat resistance and insulation performance. Many polyimide tape products use silicone adhesives, which have the advantage of leaving no residue even after being removed. Polyimide (PI) film tape not only features high-temperature resistance, chemical corrosion resistance, good insulation, and super strong adhesion, but also possesses other excellent properties such as radiation resistance, flame retardancy, wear resistance, and anti-corrosion. Polyimide (PI) tape can be classified into two types based on the adhesive used: PI silicone tape and PI acrylic tape. In terms of appearance, it is generally available in two colors: brown and black. Product Features:High temperature resistance: Polyimide film tape has good high temperature resistance and can withstand temperatures up to 400 ℃.Chemical corrosion resistance: Polyimide film tape is not easily corroded by chemical substances and has strong corrosion resistance.Good insulation: Polyimide film tape has excellent insulation performance and can effectively protect electrical equipment.Super strong adhesion: Polyimide film tape has strong adhesion and can firmly fix objects without deformation or damage at high temperatures.Anti corrosion: Polyimide film tape has excellent anti-corrosion performance, which can prevent rusting of metal materials such as steel.Product application:PI silicone tape is mainly used for applications that require high temperature resistance or high initial adhesion, such as insulation wrapping of H-grade motor and transformer coils, fixing and wrapping of high temperature resistant coil ends, thermal resistance protection for thermometers, insulation for capacitors and wire entanglement and other bonding under high temperature working conditions, temperature protection for PCB sheet metal fingers and electronic components during SMT, external wrapping of polymer lithium batteries, etc.PI acrylic tape is commonly used for insulation protection of PCB boards, fixing and wrapping of wire harnesses, interlayer and outer wrapping of transformer coils, external insulation of lithium batteries, etc.Characteristics of PolyimidePolyimide is a general term for polymer compounds polymerized by imide bonds, but the material used for polyimide tape is aromatic polyimide, which is made of aromatic compounds polymerized by imide bonds.Due to its strong adhesive strength, it has high strength, heat resistance, and insulation properties. The thermal decomposition temperature exceeds 500 ℃.The specific characteristics of the molecular structure that endow it with excellent heat resistance are as follows:Aromatic compounds have conjugated structures through imide bonds.Due to the aromatic rings being located on the same plane, the molecular chains are tightly packed together.Highly polar imide bonds have strong intermolecular forces.In addition, the coefficient of expansion during heating is relatively low, so even when used at high temperatures, it will not expand too much, thereby reducing dimensional errors.Definition of Polyimide Industry

PET double-sided adhesive tape "usually refers to a double-sided adhesive tape made of PET (polyester film) as the substrate, which combines high tensile strength and strong adhesion. The "pull resistance" of this type of tape is mainly reflected in two core indicators:Tensile strength: The maximum tensile force that the tape itself can withstand, usually measured in N/cm. The higher the value, the stronger the tape, and the less likely it is to break when stretched.Adhesive strength (such as peel force, shear force): The degree of firmness of the tape after it is adhered to the surface of an object. Even when subjected to force and pulling, excellent adhesive performance ensures that the tape will not separate from the adhered objectKey points for purchasingWhen making a purchase, in addition to comparing parameters, you also need to pay attention to these four points:Clarify the requirement for "tensile resistance": Do you need resistance to physical tension or shear force? Tensile strength and shear strength are two different concepts.Evaluate the usage environment: Do you need high temperature resistance? Long term temperature or short-term temperature? For example, 3M 9019 has a short-term temperature resistance of 121 ° C and a long-term temperature resistance of 82 ° C, while tesa 68575 has a short-term temperature resistance of up to 200 ° C.Determine the material of the adhesive: The adhesive strength of the tape to specific materials (such as low surface energy plastics PP/PE, metals, PET, etc.) may vary, and the product technical parameter table needs to be checked.Consider processing technology: If it is necessary to die cut into a specific shape, the substrate strength (such as tesa 68575) and die cutting performance of the tape are key considerations.summarySimply put, the "tensile" performance of PET double-sided tape is a comprehensive reflection of the tensile resistance of the tape substrate and the adhesive bonding ability. Choosing the right product for your application scenario is essentially finding the optimal balance between tensile strength, adhesive strength, thickness, and environmental resistanceTeflon high-temperature cloth PTFE

It perfectly combines the dimensional stability of glass fiber with the many advantages of PTFE.✨ List of Core FeaturesHere are the reasons why it has become a key material in many fields:Excellent high and low temperature resistance: It can work continuously in the temperature range of -196 ℃ to+260 ℃, and can withstand high temperatures up to 350-400 ℃ in a short period of time.Outstanding anti stick (non stick) properties: Almost all substances are difficult to adhere to and easy to clean.Extremely strong chemical inertness: able to withstand corrosion from almost all strong acids, strong bases, aqua regia, and organic solvents.Extremely low friction coefficient: The surface friction coefficient is as low as 0.05-0.1.Excellent electrical insulation: With a low dielectric constant (about 2.6), it is an ideal electrical insulation material.Good dimensional stability: The tensile elongation is extremely low, less than 5 ‰ (0.5 ‰).Fireproof and flame retardant properties: extinguish immediately upon ignition, in compliance with fire safety standards.🌡️ What is the specific temperature resistance performance?Its heat resistance is very stable:Long term stability: After continuous use at a high temperature of 250 ℃ for 200 days, its strength and weight remain basically unchanged.Short term tolerance: After being placed at a high temperature of 350 ℃ for 120 hours, the weight reduction is only about 0.6%.Extreme low temperature: In an ultra-low temperature environment of -180 ℃, the material will not become brittle and can still maintain its original softness.🏭 What are the main application areas?With these characteristics, PTFE high-temperature cloth has a wide range of applications, mainly including:The main role played by typical examples in application fieldsFood processing baking sheet, baking pad, microwave oven liner, food drying conveyor belt, anti stick, high temperature resistant, easy to clean, food grade safetyIndustrial machinery dryer conveyor belt, adhesive machine belt, sealing belt, plastic welding cloth, high temperature resistance, dimensional stability, anti sticking, wear-resistantElectronic and electrical high-frequency copper-clad laminates, insulation gaskets, cable cladding layers, high-temperature resistant tape substrates with excellent insulation, high temperature resistance, and corrosion resistanceChemical anti-corrosion pipeline anti-corrosion coating, valve sealing gasket, reactor liner, soft connection extremely resistant to chemical corrosion, good sealing performanceThe conveyor belt and covering cloth of the new energy photovoltaic module laminating machine prevent module adhesion and deformation, ensuring laminating qualityThe membrane structure roofs of sports stadiums, stations, and other buildings in the field of architecture combine high strength and flexibility, and are weather resistant and transparentOther applications such as anti-static floor mats, anti adhesive liners, and aerospace insulation layers have excellent comprehensive performance, meeting high-end needs📐 Specification and grade classificationThere are various specifications and grades of PTFE high-temperature cloth on the market to meet different needs:Grade ClassificationOrdinary industrial grade: meets the basic requirements of heat resistance, anti sticking, and anti-corrosion.Standard level: The surface is smoother, the non stick performance is better, and it is suitable for high-precision demolding and other scenarios.Food grade: Certified by FDA and other authorities, it can directly come into contact with food and is used for baking and food processing.Anti static level: The surface resistance is extremely low (≤ 10 ΩΩ), which can prevent static electricity accumulation and is used in sensitive environments such as electronic manufacturing.Thickness selectionThe thickness usually ranges from 0.08mm to 1.2mm:0.08-0.25mm: Suitable for scenarios that require high flexibility and precision, such as electronic insulation and food gaskets.0.35-0.90mm: Higher strength, more durable, suitable for heavy-duty applications such as industrial conveyor belts and pipeline wrapping.💡 Usage and selection suggestionsDistinguishing quality: When choosing, attention can be paid to its dimensional stability (elongation should be less than 5 ‰, i.e. 0.5%), whether the surface is smooth and flat, and temperature resistance. You can refer to the specific product specifications provided by various manufacturers.Safe use: For safety reasons, the temperature should be controlled below 260 ℃ as much as possible during use. If the temperature is higher than 260 ℃, the material will accelerate wear; When the temperature exceeds 300 ℃, a small amount of smoke may be released. It is important to ensure good ventilation and avoid inhalationTea colored PI gold finger heat-resistant tape
Tea colored PI gold finger high-temperature resistant tape is a single-sided tape made of polyimide (PI) film as the substrate and coated with high-temperature resistant silicone gel. It is widely used in precision protection and insulation scenarios in the field of electronics and electrical engineering due to its excellent heat resistance, insulation, and chemical resistance.🔥 Core FeaturesExcellent temperature resistance: This is its core advantage. Most products can work stably for a long time at temperatures ranging from 260 ℃ to 280 ℃, and can withstand short-term impacts of 300 ℃ or even higher. Even in extreme environments, it can maintain good physical and electrical performance.Strong insulation and protection capabilities: Its substrate polyimide itself has high insulation and high voltage resistance characteristics (some products can withstand voltages of up to 6kV or more). At the same time, it can withstand the erosion of various chemicals such as acids, alkalis, and solvents.No residual glue, easy to peel off: Applying silicone gel as an adhesive ensures that no viscous residue is left on the surface of the sticker when it is peeled off after high-temperature processing, effectively ensuring the cleanliness of subsequent processes.High mechanical strength and toughness: The product has high tear resistance and good flexibility, which can adapt to various complex surfaces and is not easily damaged.Environmental compliance: Most products comply with RoHS environmental halogen-free standards, meeting the environmental requirements of modern manufacturing industry.🎯 Main application scenariosPCB/PCBA manufacturing: During wave soldering or reflow soldering, it can effectively "protect key areas such as gold fingers" from solder contamination or high temperature damage.Electrical insulation and wrapping: commonly used for coil insulation wrapping of H-class motors, transformers, relays, and capacitors, providing reliable electrical isolation and thermal protection.Lithium battery manufacturing: In the production of lithium batteries, it is used for insulation shielding in the electrode ear (gold finger) area of the battery cell to prevent short circuits, and is easy to disassemble later due to its "no residue" characteristic.High temperature spraying and masking: can be applied in high-temperature baking paint, powder spraying and other processes as a masking and protective material, which can be easily peeled off after completion.SMT process assistance: It can be used to fix flexible circuit boards (FPCs) or fixtures during SMT surface mount reflow soldering.Precision electronic assembly: suitable for high-temperature bonding of electronic components, or positioning and fixing through customized die-cutting in automated production lines⚠️ Usage and StorageBefore use: Ensure that the surface being pasted is clean, dry, and free of oil stains to achieve the best pasting effect.When in use: It is recommended to adhere at room temperature and apply appropriate pressure; After high-temperature operation, wait for complete cooling before tearing to avoid residue.Storage: Keep in a cool, dry place, away from light and moisture, avoid heavy pressure or sharp objects from scratchingHigh temperature textured paper tape leaves no marks
1、 The principle behind 'leaving no trace'The key to achieving "no marks" on high-temperature textured paper tape lies in its synergistic effects in materials, environment, and operation:Adhesive formula: High quality products often use silicone or acrylic pressure-sensitive adhesives, which have good thermal stability and can maintain cohesion even at high temperatures, avoiding softening and infiltration into surface micro gaps.Substrate characteristics: The fine striped structure on the substrate of the masking paper reduces the ineffective contact between the colloid and the surface, ensuring that the adhesive layer falls off as a whole without leaving any traces during peeling.Environmental factors: High temperature, high humidity, or ultraviolet radiation can accelerate adhesive aging and increase the risk of residual adhesive.Attachment duration: The longer the adhesive tape is attached, the tighter the bonding between the adhesive and the surface, and the higher the risk of residual adhesive.It is usually recommended to remove the adhesive within 24 hours after attachment, as the risk of residual adhesive will significantly increase after 48 hours2、 How to use it more perfectly✅ Correct usage methodCleaning the surface: Before pasting, ensure that the working surface is clean, dry, free of oil and dust, which is the first step to ensure the pasting effect and avoid residue.Press in place: After sticking it on, use fingertips or a scraper to fully press it, ensuring that the tape is tightly attached to the surface without leaving any bubbles.Timely Tear off: After completing the work, tear off smoothly at a 180 degree angle and low speed as soon as possible to minimize adhesive residue.Try before sticking: Before using it extensively on important or sensitive surfaces (such as genuine leather or high-end paint), be sure to select a small and inconspicuous area for testing.❌ Beware of Misunderstandings in UseExcessive temperature: Tape has a clear working temperature range, and exceeding it may cause carbonization or residue. Please make sure to choose according to the product instructions.Forced fixation: Meiwen paper is mainly used for masking and temporary fixation, and is not suitable for carrying heavy objects or withstanding huge tensile forces.Long term retention: The design intention of masking tape is for "temporary use", and long-term retention will affect its performance.3、 What should I do if I encounter residual glue?Even if high-quality products are used, improper operation may still result in slight adhesive residue. You can try the following safe cleaning methods:Gentle cleaning: Dip a soft cloth in warm water and soap solution, gently and repeatedly wipe. This is the safest method for the surface.Alcohol wiping: Dip a soft cloth in a small amount of 75% medical grade alcohol and gently wipe the residue. Alcohol is relatively safe for most surfaces and is a common choice.Wind oil essence/hand cream: You can apply wind oil essence or hand cream on residual glue, and the oil components in it can help dissolve glue marks.Eraser: For residual glue on rough surfaces, you can try repeatedly wiping with a regular drawing eraser and removing it through physical friction.Professional cleaning agent: If the above methods are ineffective, a specialized adhesive remover on the market can be used, but it must be tested in an inconspicuous small area first to ensure that it will not damage the surface.High temperature flame retardant PTFE tape

At the same time, its cost is lower than high-end PC materials, making it cost-effective.2. How to understand the standard number of the carrier tape (such as EIA-481-C)?EIA-481-C is an industry standard published by the Electronic Industries Alliance (EIA), which specifies the dimensional tolerances, mechanical strength, and performance requirements for tapes and reels. The size and performance of the carrier tape produced according to this standard are uniform worldwide, ensuring smooth use on any surface mount machine that meets this standard.What does the "pocket depth" of the carrier tape refer to? What impact does it have on selection?Pocket depth "refers to the vertical height of the groove on the carrier tape used to accommodate electronic components. When selecting, it is necessary to ensure that the pocket depth is greater than the maximum thickness of the component, and usually a certain margin (such as 0.2-0.5mm) needs to be reserved to accommodate tolerances. For thicker components, it is recommended to directly choose materials with higher mechanical strength such as PC.If I only need a small amount of samples for testing, can I purchase them?Okay. Most carrier manufacturers provide sample customization services. You can directly contact the target manufacturer and provide the required resistor samples or detailed drawings for packaging. They will design and produce a small number of samples for you. However, it should be noted that the mold cost and unit price for small batch customization are usually higher.Is the anti-static performance of transparent PET tape permanent?This depends on its anti-static treatment method.Coating type: achieved by surface coating with anti-static agents, performance may deteriorate over time, friction, or moisture.Intrinsic type: Anti static components are added inside the PET material, and its anti-static performance is permanent. During procurement, suppliers can be asked specifically about the methods they use.Why do some transparent PET tapes exhibit slight colors (such as light blue or light green)?This is due to the addition of specific anti-static agents or additives to the PET substrate. In order to achieve permanent anti-static performance, some manufacturers may add special conductive polymers, which may have a very slight color tone, but this does not mean that their quality is problematicLithium battery tape
Lithium battery tape is a special tape used in the production and assembly process of lithium batteries, which plays a key role in ensuring battery performance and safety.🔎 What are the main types of lithium battery tape?There are various types of lithium battery tape, each designed for specific application scenarios and performance requirements:Main application key characteristics of the typeTerminate the tape fixation and protect the end of the battery cell to prevent short circuit, electrolyte resistance, high electrical insulation, strong adhesion, and no residue after peeling offHigh temperature tape is used for processes that require high temperature resistance, such as high-temperature shielding during ear welding, high temperature resistance (PI tape can reach 260 ℃ or above), solvent resistance, corrosion resistance, and electrical insulationWrap, insulate, and protect the positive and negative electrode ear connections with adhesive tape, which is resistant to electrolyte and has excellent heat sealing performance with metal tape and aluminum-plastic film, and is leak proofExpansion tape fixes the core, absorbs external impact forces, and enhances battery safety. It can significantly expand when exposed to electrolyte (up to three times the original thickness in volume), resist impact, and has strong fixationProtective film/blue film covers and protects the battery cells and module shells, providing insulation, wear resistance, puncture resistance, wear resistance, and high adhesionFixing/bundling tape is used to secure multiple battery cells or wiring harnesses during the module/PACK stage.

Due to its characteristics, it can be removed by stretching when needed, leaving no residue and making it easy to repair and recycle.🧪 Performance core: electrolyte resistance, temperature resistance, insulation and environmental standardsChemical Resistance: The electrolyte inside the battery is highly corrosive, and ordinary tape cannot withstand it. Lithium battery tape must be able to resist long-term immersion of electrolyte, maintain viscosity, not dissolve, and not contaminate the battery.Temperature Resistance: Temperature resistance includes two aspects: one is to adapt to the temperature environment during battery operation, for example, some adhesive tapes used in power batteries need to withstand high temperatures of 125 ℃ for a long time; The second is the high-temperature resistance process in battery manufacturing, such as polyimide (PI) tape, which can withstand temperatures above 260 ℃ for a short period of time and is used for ear welding protection.Electrical Insulation: This is the most basic safety requirement. The tape must have a high dielectric breakdown voltage, effectively isolate current, and prevent internal short circuits. For example, a tape from Desha has a breakdown voltage of up to 14400V, ensuring safety in high voltage environments.Environmental and safety standards: Many tapes comply with environmental directives such as RoHS and halogen-free. In the field of power batteries, it is also required that the tape itself has flame retardancy to comply with relevant safety regulations.Adhesion&Removability: Adhesive tape needs to have suitable adhesion to firmly fix it, but in some applications such as "easy to pull glue", it is also required to be easily peeled off without residue when it needs to be removed, making it easy to repair and recycle✅ How to choose the appropriate lithium battery tape?Clarify application scenarios: Firstly, determine whether the tape is used inside the battery cell or during the battery PACK assembly stage. The core requirements for the tape vary greatly in different scenarios.Focus on core performance: Depending on the application scenario, focus on key indicators such as electrolyte resistance, temperature resistance, electrical insulation strength, and flame retardant rating.Adaptive manufacturing process: The tape needs to adapt to the high-speed automated production line of batteries. Its physical properties such as thickness, viscosity, and stretchability can affect the efficiency and yield of equipment attachment.Confirm environmental and safety compliance: Ensure that the tape meets environmental requirements such as RoHS and halogen-free, and complies with flame retardant safety standards related to power batteries.Assessing supplier capabilities: It is recommended to choose suppliers with systematic certification (such as ISO 9001) and independent research and development capabilities, which can better ensure product quality and supply stabilityDomestic high-temperature resistant and flame-retardant insulation epoxy film tape
