Product Description

Excellent are resistance and CTI600 GPO3 glass fiber laminate sheet


Product introduction


GPO3 is also called UPGM203 plate (Unsatured Polyester Glass Mat Plate). UPGM203 is IEC standard and GPO-3 is NEMA grade. It is kind of rigid plate insulating material, made of alkali-free fiberglass mat impregnated with unsaturated polyester resin, adding relevant chemical agents in heating and pressing to cure into rigid plate.

In other way , it has fine fire retardant property and meet UL94-V0 with very low smoke , good arc resistance and tracking resistance (CTI600) , so this material has been widely used in rail traffic filed . The filler material of GPO-3 material is aluminium hydroxide , it is lower water absorption than calcium carbonate and better fire resistance . Lower absorption means better electrical performance . 


Good arc resistance property means not easy to carbonization when impact by arc , as we known if the material is carbonization , insulating strength has been decreased . so it is the safety material. It's widely used in the low voltage electrical industries such as making of insulating sheet in UPS , top cover and bottom cover in transformer .
