CR Corona Resistant Polyimide Film
CR polyimide film was developed specifically to withstand the damaging effects of “corona”, which can cause ionization and eventual breakdown of an insulation material or system when the voltage stress reaches a critical level. Corona resistant polyimide film has preserved the physical, mechanical property of polyimide film as it does, as well as the outstanding corona-resistant property.
