Polyimide film (PI) has superior heat resistance and cold endurance, keeping a normal operation characteristic in a wide temperature range: -270 - +400°C.
It’s widely used in various kinds of motors, electrical apparatus and wires and cables to be used under extreme conditions and need high operational reliability.
