Kapton®
Product description
Kapton® film (developed by Dupont™) is a polyimide film that has exceptional electrical, mechanical, physical and chemical properties. The thermal class of Kapton, in use, is Class C, which corresponds to a temperature index above 240°C.
Thanks to these extraordinary characteristics, Kapton® is a flexible insulator that remains stable in the face of extreme temperatures, allowing it to be used between -269 degrees and + 400 degrees. Kapton® film, or polyimide film, can be used in various industrial applications requiring important electrical, mechanical or thermal properties.
For applications subject to high heat and vibration, Kapton® is used extensively for its ability to maintain its unique combination of properties under the most difficult conditions.
Technical properties
- Self-extinguishing (UL94 V-0)
