Polyimide Film & Tape
Our polyimide film is widely used for electrical and electronic appliances with properties of heat resistant(-60c_250c), chemical resistant(almost no organic or inorganic solvents except caustic alkali), dielectric, flame retardant, physical, mechanical and compounded with many materials performances.
