BOPI Biaxial Orient Polyimide Film (Tape)

BOPI (Biaxial Oriented Polyimide film) is Polyimide Polycondensate by polycondensing PMDA and DDE through the process of forming film in strong solvents and then being stretched and Oriented by biax during the course of imine at high temperature. BOPI film is a special kind of Polyimide film, however, as the result of Biaxial Orientation, BOPI film possesses higher physical, chemical, and electrical properties, which performs successfully in the wide range of temperature as low as -452F(-269c) and as high as +436F(+260c) and can be exposed at +752F(400c) in short time, besides, it is of atomic radiation resistant. BOPI film is currently the macromolecular compound with the best combined properties and the highest heat resistant
