Product description
Polyimide CR 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 singe side or double sides of the corona resistance polyimide film. Slit with different width after drying and rolling.
II.Technical requirement
1. Appearance
  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
III.The Thickness and Its Tolerance 
                                                                            Unit : mm
