In der Luftfahrt gibt es das hoch tempperaturbeständige Kapton, was bereits in dünnen Schichten gut isoliert, leider ist es brennbar und zudem sehr teuer
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).
