The plastic polyimide (PI) is a temperature-stable thermosetting plastic used in electronics
. Polyimide is used as an insulating material for cables or in PCB technology as a base material
forflexible printed circuit boards. Flexible, copper-clad multilayer printed circuit boards with prepregs
can be pressed together from polyimide film. Polyimide is a high-performance plastic with the DIN/VDE designation 8Y. It is characterized by heat resistance and good insulating properties. Polyimides require temperatures of 350 °C to 390 °C for curing.
