Corona-resistant (CR) polyimide film offers superior resistance to corona partial discharge compared to conventional polyimide films. It retains the excellent physical, electrical, thermal, and chemical resistance properties typical of polyimide films. In addition, you can coat CR polyimide film with pressure-sensitive adhesives. Coating with FEP fluoropolymers can make FCR polyimide film, expanding its versatility and range of applications.

CR polyimide film is used as an electrical insulation material in high-voltage environments prone to corona discharge. In addition, it provides excellent protection against ionization and material breakdown, ensuring reliable performance. Typically, the industry uses it for magnet wire, inter-turn wire, coils, slot liners, and ground insulation in motor and generator applications. Its rugged properties ensure reliability and performance under harsh conditions.
Corona-resistant CR Kapton polyimide film is widely used in electrical applications such as coil insulation, capacitor and transformer wrap, and magnet wire insulation.
In addition, you can coat FCR polyimide film with hot-melt FEP fluoropolymer on one or both sides of the film. This variant offers the excellent physical, electrical, thermal and chemical resistance that polyimide films offer. Specifically, FCR019 has been developed for magnet wire insulation in rail traction, industrial motors and generators where extended insulation life in partial discharge environments is critical.

Common applications include:

AC variable frequency motors
Railway and automotive traction motors
Hydraulic and wind turbines
Transformers
Magnet wire
