China Factory Manufacture Thermal Resistant Electrical Insulation Yellow Polyimide Film

Description  Polyimide (PI) is a polymer of imide monomers, aslo know as heat resistant film or high temperature film. With their high heat-resistance, polyimide enjoys diverse applications in roles demanding rugged organic materials. Polyimide film is ideal for insulating circuit boards, high temperature powder coating and transformers manufacturing. Polyimide film provides excellent electrical, thermal, physical and chemical properties over a wide temperature range between -269ºC (-452ºF) and 400ºC (752ºF) making them superior for electrical insulation applications. Polyimide film can be laminated, metalized, punched, formed or adhesive coated. BOPI film has better thickness tolerancem,highter physical, chemical,and electrical properties. It is the recommended choice for applications that require an all-polyimide film with an excellent balance of properties over a wide range of temperatures. we can provide both standard and custom polyimide film solutions for a customer depending on their needs. eatures Excellent thickness tolerance property Temp resistance from -452ºF to over 752ºF(-269ºC to over 400ºC) Easy coating property Excellent balance of electrical,chemical and physical property Flame retardant Radiation retardant Main Specification Properties Unit Values Um(Mil) 12.5(0.5) 25(1) 50(2) Density g/cm³ 1.42±0.2 1.42±0.2 1.42±0.2 Tensile Strength MD≥ MPa 170 170 170 TD≥ 170 170 170 Elongation at rupture ≥ % 60 70 70 Breakdown Strength MV/m 250 240 240 Heat Shrinkage 200ºC 2hrs≤ % 0.1 0.1 0.1 Surface Resisitance Ω 1.0×1013 1.0×1013 1.0×1013 Volume Resistance Ω.m 1.0×1010 1.0×1010 1.0×1010 Loss Tangent 0.004 0.004 0.004 Slitting and Packging Width:520mm~1040mm Core ID:76mm(3'')or 152mm(6''),Core materials:Paper or plastic Packaging:PE film packaged,with aluminum foil and foam,Suspended packing.
