Thermal conductivity properties ideal for controlling and managing heat in electronic assemblies
DuPont™ Kapton® MT polyimide film is a homogeneous film possessing 3x the thermal conductivity and cut through strength of standard Kapton® HN.
Kapton® MT offers an excellent combination of electrical properties, thermal conductivity and mechanical toughness for its use in electronic and automotive applications.
Kapton® MT has higher modulus than HN; this offers improved strength to the final product. As all Kapton® films, MT retains its properties for extended storage periods in original packaging at temperatures between 4–29°C (40–85°F).

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.
DuPont™ Kapton® FN is a general purpose HN film that is coated or laminated on one or both sides with Teflon® FEP fluoropolymer.
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® 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® 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.
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® FCR is a state-of-the-art wire insulation that will withstand corona discharge while delivering improved long term performance, cost effectively.
DuPont™ Kapton® FPC polyimide film is treated on both sides with excellent balance of physical, chemical and electrical properties over a wide temperature range.
In applications where low shrinkage and superior adhesion are important, Kapton® HPP-ST is the polyimide film of choice.
