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® 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® 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® 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® 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® 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® FPC

DuPont™ Kapton® FPC polyimide film is treated on both sides with excellent balance of physical, chemical and electrical properties over a wide temperature range.

Kapton® FWN

Kapton® FWN is ideal for demanding magnet wire applications and for difficult-to-wind motors.

Kapton® FWR

Proper insulation design and application of these materials will provide a tough, high dielectric strength insulation with improved hydrolysis resistance compared to other commonly used polyimide containing materials.

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® 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® HPP-ST

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

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® MT+

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

Kapton® PRN

DuPont™ Kapton® 150PRN411 is ideal for insulating copper conductor used in high temperature magnet wire applications.

Kapton® PST

Kapton® PST is a tough film that exhibits an excellent balance of physical, chemical and electrical properties over a wide temperature range, particularly at unusually high temperatures.

Kapton® PV9100 Series

Kapton® polyimide film minimizes the stress at the interface during high temperature thin film deposition and processing.

Kapton® RS

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