Among high-performance films, Kapton® from DuPont is certainly at the top. This high-quality polyimide film has been produced for over 40 years. Kapton® films are characterised by very high quality, an absence of faults and the best chemical, physical and thermal properties characteristics. Compared to cheaper polyimide films, Kapton has the highest thermal resistance, as is confirmed by UL (E39505). Many polyimide films only have a classification for 130 °C (class B).

The high thermal resistance, combined with effective adhesives for (short-term) temperatures up to 350 °C, makes Kapton® adhesive tape attractive for high-temperature applications. The service life of a machine can also be increased dramatically by using Kapton® adhesive tapes. When equipped with a high-quality, fully cross-linked polysiloxane adhesive, Kapton® adhesive tapes also withstand stresses from caustic chemicals, weathering, and high voltages, as are found in large transformers and electric motors.
