Kapton® Polyimide based film
Kapton® (Kapton® is DuPont's registered trade mark) polyimide film is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. With its excellent physical, chemical and electrical properties Kapton® film can be used in a wide temperature range (-269÷+400°C).
Kapton® is available in different versions according to the application.
The base type is Kapton® HN. It is mainly used for the insulation of electrical motors in class H and super H, in the production of adhesive tapes for dielectric uses and when resistance to extreme temperatures is required.
Kapton® FN is the HN type coated on one or both sides with Teflon® FEP, that enhances chemical resistance and imparts heat sealability. It is used for the covering of copper wires and cables in high temperature applications.
Kapton® CR (available also with a coating in Teflon®: FCR) was developed to withstand the damaging effects of corona.
Kapton® MT is appropriate for all applications where an high thermal conductivity is required.
Kapton® FPC, in its different versions, is suitable for the production of flexible circuits.
