Application of electromagnetic induction heating roller PI film stretching equipment

Polyimide (PI) film is a thin film insulation material made by the condensation and casting of phthalic anhydride and diaminodiphenyl ether in a strongly polar solvent, followed by imidization.The PI film is yellow and transparent, with a relative density between 1.39 and 1.45. It has excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, and dielectric resistance, and can be used inLong term use within the temperature range of 269 ℃ to 280 ℃ has been widely applied in high-tech fields such as aviation, aerospace, machinery, electrical, atomic energy, microelectronics, and liquid crystal displaysIt has become one of the indispensable materials in the fields of global rocket and aerospace technology. For foldable phones, traditional glass materials are hard and fragile, and flexible substrate materials replace traditional rigidityGlass substrate is one of the key elements for achieving product flexibility, and PI film has become the current flexible substrate material due to its excellent high-temperature resistance, mechanical properties, and chemical stability.

Mainly used in the production of PE lithium battery separators; PP, PE sanitary breathable film: The most widely used batteries in the fields of single and double directional stretch films in the PP, PE, PET, PS heat shrink packaging industry, as well as in modern digital products such as mobile phones and laptops.
