Polyimide Film (similar to Kapton HN)

Kapton HN Polyimide film

Properties

Polyimide film (similar to Kapton HN) is achieved by polycondensation of PMDA and ODA in strong polar solvents and 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 wide range of temperature as low as -452F(-269c) and as high as +500F(+260c). Because of its unique excellent properties, it is the most ideal choice in many applications.
