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.
