Polyimide corona resistance Film (Kpt CR)
Advance and application:
1.The polyimide CR film is produced by "Doctor-blading Process". It is an excellent alternative of the Kapton tape
produced by Dupont.
2. Size
1)Thickness: from0.025mm to 0.075mm，can be customized
2) Width: from 10mm to 600mm
3) Length: can be customized
