Corona resistance polyimide films coated with F46 composite adhesive tape, not only with ordinary polyimide film electrical properties, good heat resistance and resistance chemicals, but also with the super corona resistance and good thermal conductivity performance, mainly apply to sintering electromagnetic winding wire, traction motor, wind generators, and the special motor turn-to-turn insulation and heat insulation, the heat resistance level is above class C.
The corona resistance (voltage endurance) is 80,000 hr at 20 kV/mm at 50 Hz by IEC 343 testing method.
The technical requirements
1. Type
CR type: Corona resistance polyimide film without any F46 coating
FCR type: Corona resistance polyimide film with F46 single side coating
FCRF type: Corona resistance polyimide film with F46 double side coating
2. Appearance
Its appearance is golden brown, translucent, the surface is bright and clean, no wrinkles, tear, particles, bubble, pinhole and foreign material defects. Its edge is tidy, and without damage.
3. Thickness and allowable deviation
