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?High 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

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
