Polyester film shows good dielectric properties, heat stability and high mechanical strength as well as size stability, air tightness. It is suitable for insulation in medium and small size cable wrapping insulation. And applied as insulation materials, film composites in domestic electrical appliances as well as other insulating materials for...

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...

Polyimide FEP film is Polyimide film(BOPI) coated with FEP(F46) resin on one side(FH) or double sides(FHF) through the sintering process at high temperature, which combines the excellent properties of Polyimide film and FEP(F46) resin, high& low temp resistant, radiation resistant, excellent electrical properties, superior dimensional stability...

Polyimide film is synthesized by polymerizing PMDA and ODA in strong polar solvents through the process of forming film and imine treatment at high temperature, which possesses excellent physical, chemical, and electrical properties, atomic radiation resistant, solvent resistant, low & high temperature resistant, It performs successfully in the...
