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.
