Polyimide film and F46 composite film exhibit excellent resistance to high and low temperatures, electrical insulation, adhesion, radiation, and medium resistance, allowing for long-term use within a temperature range of as low as -269°C to as high as +400°C. The composite film also features self-adhesive sealing at high temperatures. They can be used as flexible printed circuit base materials for high and low temperature resistance, flat circuits, wire and cable insulation, and electromagnetic wire insulation, as well as for insulation in various motors. They are currently widely used in industries such as aviation, spacecraft, nuclear industry, nuclear submarines, electric locomotives, audio devices, instrument communication, and petrochemicals.
