KAPTON high-temperature tape, that is, adhesive tape used in high-temperature working environment. Mainly used in the electronic industry, the temperature resistance is usually between 120 degrees and 260 degrees. It is often used for fixing, printed circuit boards and high-temperature treatment and shielding in the process of electric KAPTON high-temperature tape sub-parts. High temperature tape includes KAPTON high temperature tape, Teflon high temperature tape, high temperature masking tape, PET green high temperature tape; High temperature double-sided adhesive, etc. 

      01. KAPTON high temperature tape 

      Tape is a kind of item that is often used in daily production, and Golden Finger High Temperature Tape is a special kind of tape in tape. Also known as Kapton tape, the tape uses golden finger film as the substrate, coated with high-performance * * silicon pressure-sensitive adhesive on one side, and has two types of materials: single-sided fluoroplastic release material composite or non-composite. Coating with high precision of ± 2. 5um, no scratches, wire drawing and other phenomena, good shear, easy to punch die-cutting processing, excellent high temperature resistance and solvent resistance. The storage conditions of the golden finger tape are 10-30 °C, and the relative humidity is 40-70%; Avoid direct sunlight and high temperature (above 40 °C) and high humidity (75% RH) environments.

       02. Features of KAPTON high temperature belt 

      Golden finger tape has high and low temperature resistance, acid and alkali resistance, electrical insulation, radiation protection and other properties, high adhesion, soft clothing and re-tear non-residual glue and other characteristics. When the golden finger tape is torn off after use, there will be no residual glue on the surface of the protected object. 

      03. Application of KAPTON high temperature belt 

      Paint: Used as insulating paint for magnet wires, or used as high temperature resistant paint. 

      Composite materials: Used in aerospace, aircraft and rocket components. It is one of the high temperature resistant structural materials.

       Fiber: The modulus of elasticity is second only to carbon fiber. It is used as a filter material for high-temperature media and radioactive materials, as well as bulletproof and fabric. 

      Styrofoam: Used as heat resistant and insulating material. 

      Engineering plastics: There are thermosetting and thermoplastic types, which can be molded or injection molded or transfer molded. Mainly used for self-lubrication, sealing, insulation and structural materials. 

      Photoresist: It can also be used as a photoresist. There are negative glue and positive glue, and the resolution can reach sub-micron level. With pigments or dyes can be used in color filter film, can greatly simplify the processing process.

       Applications in microelectronic devices: As a dielectric layer for interlayer insulation, as a buffer layer can reduce stress and improve yield. As a protective layer, it can reduce the impact of the environment on the device, and can also shield a-particles, reducing or eliminating soft errors of the device. 

      Alignment agent for liquid crystal display: It occupies a very important position in the orientation agent materials of TN-LCD, SHN-LCD, TFT-CD and future ferroelectric liquid crystal display. 

      Electro-optical materials: used as passive or active waveguide materials, optical switching materials, etc. Fluorine-containing materials are transparent in the range of communication wavelengths, so as to improve the stability of materials as a chromophore matrix. 

      Humidity sensitive material: Using its hygroscopic linear expansion principle can be used to make humidity sensors.
