Product Highlights

Corona Resistant (CR) Polyimide Film : Corona Resistant (CR) Polyimide film was designed 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
  • Excellent electrical properties
  • High-Temperature Resistance


Corona Resistant (CR) polyimide film is a homogeneous film possessing improved resistance versus traditional polyimide films when exposed to the damaging effects of coronal partial discharge. In addition to the corona resistant properties, it offers excellent, physical, electrical, thermal and chemical resistant characteristics expected with polyimide films. It can also be coated with pressure sensitive adhesive, or it can be coated with a FEP fluoropolymer creating FCR polyimide film.
