Polyimide film adhesive tape ST650
Properties and Application:
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 wide range
of temperature as low as -452F(-269c) and as high as +752F(+400c). Because of its unique excellent properties, it is
the most ideal choice in many applications.
