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 insulationexternal 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
2.1 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
Type | Tolerance |
TY6051-CR | 0.020～0.040 | ±0.002 |
0.041～0.075 | ±0.004 |
TY6251-FCR (single side or double sides) | 0.030～0.050 | ±0.003 |
0.051～0.100 | ±0.005 |
Remarks: We can meet your needs of all kinds of specification of
corona resistance polyimide film and adhesive tape.
IV width and length
We can meet your needs of different width and length.
