Sell insulation material corona resistant kapton pi film @China (Mainland)
Corona-resistant polyimide film is aimed at high power frequency control motor insulation. It Adopting advanced dispersion technique —inorganic nano-particlesGreatly improve the performance of corona-resistant corrosion.
Excellent properties:
1.corona-resistant property;
2.other properties better than PI film.
Application:
It is used widely in high power frequency control motor.
