Introduction of polyimide film line

● Product name: polyimide film line use copper (aluminum) conductor lapped by polyimide film or polyimide fluoride 4.6 composite film, then heated in order to bond thin film and conductor. This product has good voltage resistance and thin insulation thickness, heat resistance can reach 220 ℃, it is mainly used in motor, reactor, electric welder and other similar products. Electrician naked copper (aluminum) conductor with extrusion process is ideal material for polyimide film line.
