Kapton® CRC

Kapton® corona resistant film withstands the damaging effects of corona discharge

The corona resistance provides improved service life and operational efficiencies versus conventional insulation materials.

Kapton® 100CRC 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, Kapton® CRC offers excellent, physical, electrical, thermal and chemical resistant characteristics expected with Kapton® polyimide films.

Kapton® CRC polyimide film has been developed for use as an electrically insulating material for high voltage environments where the potential for corona discharge is present. Kapton® CRC is typically used in industrial motor and generator applications as magnet wire, turn to turn strand, coil, slot liner and ground insulation materials. It has also been used to form laminates with other materials, such as DuPont™ Nomex® paper or mica insulations, to provide a tailored electrical insulation property.
