Polymide film is a kind of special plastic film, flat and smooth, no crease, no particular air bubble and no pinhole, with excellent mechanical properties, 
      dielectric properties, long-term working temperature-195 degree to 280 degree, widely used in sophisticated products in  appliance, statellite navigation, digital product, electric motors, computer, mobile phone and so on, such as the base dielectrics in flexible printed circuits (FPC), tape automated bonding (TAB), pressure sensitive tape (PST), and insulation for electric motor(Insulation). It has excellent electrical insulation properties, mechanical properties, excellent temperature resistance, resistance to Radiation, chemical stability and flame retardancy and etc. it is widely used for wire insulation wrapping and coil insulation binding of largeindustrial motors, traction motors, and generators.
