Corona Resistance Polyimide Film

 

In addition to the very good performance of high and low temperature resistance, electricity insulativity, radiation and etching resistance, it also has very excellent performance of corona resistance and thermal conductivity. The corona polyimide film applies to turn-insulating, major insulation, external insulation of big coil and corona resistance protective layer of large tractive motor, conversion motor, wind driven generator, special motor etc.

 

I Type

TY6051-CR corona resistance polyimide film

TY6251-FCR (single side, double sides), painted F46 glue on the surface of the single side or double sides of the corona resistance polyimide film. Slit with different width after drying and rolling.

II Technical requirement

2.1apperance

The color of the corona resistance polyimide film is amber and semi-transparent. The film should be smooth and flat with neat non-torn edges and without any defects such as wrinkles,tears, gels, blisters, bubbles, pinholes and foreign impurities.
