Polyimide Film Tape

Polyimide Film Tape


Polyimide salivating film is an H-class insulating film with pyromellitic dianhydride 4,4-
diaminodiphenyl ether as the main raw material. It has excellent insulation performance and super high
temperature resistance, corrosion resistance, tension resistance, radiation resistance and excellent flame
retardant performance.
