Kapton laser cutting

Kapton is a polyimide film developed by DuPont in the late 1960s that remains stable (in isolation) across a wide range of temperatures, from −269 to +400 °C (−452 to 752 °F; 4 to 673 K). Kapton is used in, among other things, flexible printed circuits (flexible electronics) and space blankets, which are used on spacecraft, satellites, and various space instruments.
