  • Kapton® FN

    DuPont™ Kapton® FN is a general purpose HN film that is coated or laminated on one or both sides with Teflon® FEP fluoropolymer.

  • 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® B

    DuPont™ Kapton® B polyimide film exhibits an excellent balance of physical, chemical, and electrical properties over a wide temperature range, with superior dimensional stability at elevated temperatures.

  • Kapton® FCRC

    Kapton® FCRC combines corona resistant polyimide film with a heat fusible FEP fluoropolymer film. The corona resistance provides improved service life and operational efficiencies vs conventional insulation materials.

  • Kapton® PV9100 Series

    Kapton® polyimide film is widely used as a dielectric substrate for its high temperature resistance, self extinguishing burn characteristics, toughness and flexibility.

  • Kapton® MT

    DuPont™ Kapton® MT polyimide film is a homogeneous film possessing 3x the thermal conductivity and cut through strength of standard Kapton® HN.

  • Kapton® HN

    Kapton® HN is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures.

  • Kapton® GS

    Kapton® GS film has been specifically designed and manufactured to expand the processing window and improve yields during artificial graphite sheet production.

  • Kapton® HPP-ST

    In applications where low shrinkage and superior adhesion are important, Kapton® HPP-ST is the polyimide film of choice.

  • Kapton® FCR

    Kapton® FCR is a state-of-the-art wire insulation that will withstand corona discharge while delivering improved long term performance, cost effectively.

  • Kapton® CR

    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® RS

    Kapton® RS is an electrically conductive polyimide film developed for applications in which a precisely controlled surface resistivity is needed.
