Introduction of Polyimide Film

Polyimide film is widely used in various electrical machines, electrical appliances and cables because of its high temperature resistance, radiation resistance, chemical corrosion resistance and electrical insulation properties.

Polyimide film has excellent heat and cold resistance, can be used for a long time at 250 ℃, in 400 ℃ can work for hours, more than 800 ℃ carbonization, but not combustion; in liquid helium temperature can maintain flexibility,can withstand all organic solvents and acids, but not strong alkali, and, it's not suitable for using in oil. It has the characteristics of wear resistance, arc resistance and high energy radiation.
