Kapton® polyimide film is synthesized by polymerizing an aromatic dianhydride and an aromatic diamine. This material offers outstanding longevitiy and is hightly resistant to an extremely wide temperature range (-269°C to 400°C). Together Besides these excellent physical, chemical and electrical properties Kapton® polyimide film provides important weight and space savings and is suitable for variety of electrical and electronic insulation applications such as formed coil insulation, motor slot liners, magnet wire insulation, transformers and capacitors.
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.
