Our company has long been supplying yellow, brown and gold polyimide PI films. Polyimide PI film has excellent resistance to high and low temperature, electrical insulation, adhesion, radiation resistance, dielectric resistance, chemical stability, humidity and heat resistance, and excellent mechanical properties. It can be used at -269 ℃ ～ + It can be used for a long time in the temperature range of 280 ℃, and can reach a high temperature of 400 ℃ in a short time. Colors are generally three types: the most common ones are transparent brown (also called golden yellow, yellow), black (glossy, matte), and transparent (high price and difficult to produce). The production process generally used is unidirectional stretching, biaxial stretching, and casting. Our yellow, brown, gold polyimide PI film has excellent performance, it is widely used in space technology, F, H motors, electrical insulation, FPC (flexible printed circuit board), TAB (pressure sensitive tape (Basic talent), aerospace, aviation, computer, electromagnetic wire, transformer, audio, mobile phone, computer, smelting, mining electronic components industry, automobile, transportation, atomic energy industry and other electronic and electrical industries. The thickness of our yellow, brown, and gold polyimide PI films are: , 0.150mm, 0.175mm, 0.20mm, 0.225mm, 0.25mm, etc., the coil width is generally about 520MM, 1040MM, the weight of each coil is generally 20 to 30 kg.
