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.
