Thick Polyimide film is usually including the kapton film more than 0.1mm, it is is a 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. With its excellent physical, chemical and electrical properties Kapton film can be used in a wide temperature range (-269+400°C). It is widely used for the insulation of electrical motors in class H and super H, in the production of strength film for dielectric uses and when resistance to extreme temperatures is required. It also offers good dimensional stability and can be die-cut, laminated, metallized, formed, thermoformed. |
