A family of some of the most heat-resistant polymers known. Tough polyimide film Kapton* (DuPont) has excellent abrasion, cut-through and impact resistance and high levels of resistance to oxidation, weathering and all chemicals except strong bases. It has been used in applications from extremely low temperatures of -269 C to as high as 400 C (750 F) in wire applications, Kapton is at present used up to 250 C temperatures, with retention of outstanding electrical properties.
