Kapton® Corona Resistant (CR) polyimide film

DuPont Kapton® 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.

Kapton® corona resistant film is a state of the art polyimide film that withstands the damaging effects of corona discharge. The corona resistance provides improved service life and operational efficiencies versus conventional insulation materials.
