Description：Polyimide film is a kind of high performance polymer through polycondesation of symbenzene tetracarbonic acid dianhydride and diaminodiphenyl ether, which combines excellent physical, electrical and mechanical properties at temperatures as low as -269℃(-452℉) to as high as +400℃(+752℉).
Features ：
∙ Wide range of temperature from -269℃(-452℉) to +400℃(+752℉).
∙ Excellent electrical insulation properties
∙ Flame and radiation retardant
∙ Easy coating
Application：
∙ Wire and cable insulation, interlayer insulation in motor, transformer etc
∙ Polyimide adhesive tape or polyimide laminates
∙ Polyimide tubing
∙ Polyimide label
