Company Introduction: Shandong Xinhongyun New Material Technology Co., Ltd.Located in weifang city, shandong provience., is a ISO certified professional & reliable manufacture of electrical insulation materials-BOPI FILM(polyimide film). our annual prodcution capacity is 150-200MT.main thickness 12.5um,25um & 50um, main width 514mm,520mm,1028mm&1040mm.main color: yellow, red, matte black. we have strict quality inspection system ,we trust we can supply you best quality product with high quality 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 -269�ºC� (-452�ºF) and 400�ºC� (752�ºF) 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.
