Polyimide Film (similar to Kapton® HN)
Properties
Polyimide film (similar to Kapton® HN) is kind of special engineering plastic film which 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. Polyimide film (similar to Kapton® HN) possesses excellent physical, chemical, and electrical properties, atomic radiation resistant, corrosion and 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, polyimide film (similar to Kapton® HN) is widely used as insulation material in F~H class electric motors, electric locomotive, high temperature cables, backing or cover film of FPCB (flexible printed circuit) applications, aerospace industries and so on.
