Kapton® films made of polyimide (PI)
For high temperature applications
Kapton® polyimide films combine electrical, thermal, chemical and mechanical properties that are not otherwise found in this unique combination in polymer film materials. Due to their performance within a wide temperature range, Kapton® films open up a wide range of design and application possibilities. Kapton® polyimide films are particularly suitable for applications under high operating temperatures where other plastic films fail.
Mechanical and thermal properties
Kapton® polyimide films retain their excellent physical properties over a wide temperature range. Unlike other organic films, Kapton® polyimide films do not tend to flow under pressure and temperature loads.
Kapton® polyimide films are characterised by excellent electrical properties. Dielectric strength and dissipation factor remain almost constant within a wide temperature and frequency range. Kapton® polyimide films type CR have a high resistance to corona discharges.
Kapton® polyimide films offer a high level of chemical resistance to a wide range of chemicals, including solvents and oils.
