Products Description
Polyimide film is insulation material. It is made of pyromellitic dianhydride (PMDA) and diaminodiphenyl ether (ODA) in a highly polar solvent through polycondensation and co-flow. It is formed into a film and then imidized.
The polyimide film is yellow and transparent, with a relative density of 1.39 to 1.45. The polyimide film has excellent high and low temperature resistance, electrical insulation, adhesion, radiation resistance, and medium resistance. It can operate at 269°C to It can be used in a temperature range of 280℃ for a long time and can reach a high temperature of 400℃ in a short time.
Because of its excellent high temperature resistance, chemical resistance and electrical insulation properties, it is widely used in electronics, aerospace, medical and other industries.
