The polyimide heating film also called PI heating film. Polyimide is the better insulation material for polyimide heating film in the world.The polyimide heating film is made of polyimide film as the outer insulator, and metal foil and wire as the inner conductive heating element.
It has excellent mechanical properties, electrical properties, chemical stability, high radiation resistance, high temp. resistance, low tempe. resistance (-269℃~400 ℃). The polyimide of the power battery heating sheet is one of the organic polymer materials with better comprehensive performance. Its high tempe. resistance can reach above 400℃, long-term use temp. range -200～300℃, some have no obvious melting point, high insulation performance, dielectric constant 4.0 at 103 Hz, dielectric loss only 0.004～0.007, belonging to F to H.
