Technical Information

Corona Resistant Polyimide Film (CR/FCR)

Product No. MAF04

Q-MANTIC ® CR polyimide film is developed specifically to withstand the damaging effect of “Corona”. The CR type polyimide film not only maintains its excellent physical, electrical, thermal, mechanical and chemical properties, but also has good corona resistance and thermal conductivity. FCR film is FEP coated CR type polyimide film with corona resistant property.
