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.

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 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
