Kapton is a polyimide film used in flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments. Invented by the DuPont Corporation in the 1960s, Kapton remains stable across a wide range of temperatures, from 4 to 673 K (−269 to +400 °C). Kapton is used in ...
Chemical structure of Kapton, a polyimide. Polyimide (sometimes abbreviated PI) is a polymer containing imide groups belonging to the class of high-performance plastics.With their high heat-resistance, polyimides enjoy diverse applications in roles demanding rugged organic materials, such as high temperature fuel cells, displays, and various military roles.
Polyimide pressure delicate adhesive (PSA) tape is in fact produced up of two separate actions. The very first will be the manufacture in the Polyimide film tape, itself (the generic name of DuPont’s trade name Kapton®), along with the second is applying an adhesive backing based on the meant application.
The high temperature and chemical resistance of polyamide-imides make them in principle suitable for membrane based gas separations. The separation of contaminants such as CO 2, H 2 S, and other impurities from natural gas wells is an important industrial process. Pressures exceeding 1000 psia demand materials with good mechanical stability.

provides operating temperatures from cryogenic to 300 °C (570 °F), high plasma resistance, as well as a UL rating for minimal electrical and thermal conductivity. This is the unfilled base polyimide resin. It also provides high physical strength and maximal elongation, and the best electrical and thermal insulation values. Example: Vespel SP-1.
