The most outstanding characteristics of Polyimide film is for its high temperature endurance and insulation ability. To make a polyimide film, first form the film by condensing pyromellitic dianhydride(PMDA)and Diamino diphenyl ether(DDE) in strong solvents, and then be treated by imine at a high temperature It exhibit excellent thermal resistance, high insulation resistance, engineering properties, chemical stability, radiation resistance, inflammability and fire resistance rated at 94V-0. The product is halogen-free, and meets the environmental protection standard for its heavy metal and other restricted organic materials.
