Product Description

Corona-resistant polyimide film is aimed at high power frequency control motor insulation. It is produced with adopting advanced dispersion technique which put the inorganic nano-particles into the film, so it can improve greatly the performance of corona-resistant corrosion. It is used widely in high power frequency control motor, and it can increase the reliability and life of such motor with using it to make corona-resistant insulating layer around the envelope and main insulating layer.

Excellent properties:

1.corona-resistant property;

2.other properties better than PI film.

Application:

It is used widely in high power frequency control motor
