BOPI (similar to Kapton HN)
Kapton FN BOPI

Properties

BOPI (Biaxial Oriented Polyimide film, similar to Kapton HN) is achieved by polycondensation of PMDA and ODA in strong polar solvents, through the process of film forming, 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 +500F(+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.
