Polyimide Resin(abbreviated as PI) refers to a class of polymers containing an imide ring (-CO-NR-CO-) [2] on the main chain. It is one of the organic polymer materials with the best comprehensive performance. It has a high temperature resistance of over 400°C and a long-term operating temperature range of -200 to 300°C. Some of them have no obvious melting point and high insulation performance. The dielectric constant is 4.0 at 103 Hz and the dielectric loss is only 0.004 to 0.007, which belongs to F to H grade insulation.
| 1. Film: One of the earliest products of polyimide, used for slot insulation of motors and cable wrapping materials. 2. Coating: Used as insulating paint for electromagnetic wires, or as high-temperature resistant coatings. 3. Advanced composite materials: One of the most high-temperature resistant structural materials 4. Fiber: The elastic modulus is second only to carbon fiber, used as a filter material for high-temperature media and radioactive substances, and bulletproof and fireproof fabrics. 5. Foam plastics: Used as high-temperature resistant insulation materials. 6. Engineering plastics: Mainly used for lubrication, sealing, insulation and structural materials. 7. Adhesives: Used as high-temperature structural adhesives 8. Separation membranes: Due to the heat resistance and organic solvent resistance of polyimide, it is of particular importance in the separation of organic gases and liquids. 9. Photoresist: Can be used in combination with pigments or dyes for color filter films 10. Application in microelectronic devices: Used as a dielectric layer for interlayer insulation, and as a buffer layer to reduce stress and improve the yield rate. 11. Orientation agents for liquid crystal displays 12. Electro-optical materials: used as passive or active waveguide materials, optical switch materials, etc. 13. Hygroscopic materials: can be used to make humidity sensors based on the principle of linear expansion due to moisture absorption. |
