Dupont Kapton

What is Kapton?

Dupont Kapton is a polyimide film made by DuPont which has outstanding characteristics that were previously unavailable from polymeric film materials. Kapton has been especially successful in applications involving high operating temperatures because of its ability to maintain its excellent physical, electrical, and mechanical properties.

Dupont Kapton can be used at both high and low temperatures where other organic material would not be functional. It is flame resistant and there is no known solvent for the film. It can be laminated, metalized, punched, formed, or adhesive coated. Kapton is available in several formulations, including Teflon coated, which improves its chemical resistance, and heat sealability.
