Polyimide Log Roll
Polyimide film combines a high thermal resistance, anti-radiation and excellent dielectrical properties. The product is designed as electrical insulating material for applications in motors and transformers with continuous operation temperature ≥180°C.
Polyimide film is produced with a smooth surface without scratches and bubbles. The film is translucent and has a yellow/orange colour.
