Polyimide Fluorine Composite Film Polyimide Film
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).
