What is UPGM203 ?
UPGM 203 laminate material also known as GPO-3 material, UPGM203 is IEC standard and GPO-3 is NEMA grade , it is alkali-free fiberglass mat dipped into unsaturated polyester resin added relevant chemical agent as the basic material pressed under high temperature press into rigid panel as insulating material. It has good electrical property under high humidity and high mechanical property under medium temperature, fine fire retardant property, good arc resistance and tracking resistance. It's widely used in the low voltage electrical industries such as making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch-gear and other types of electrical apparatus.
Could you introduce the features ?
it is the environmental protection material meet RoHs and Reach requirement ;
it is halogen-free flame retardant , it has the property on fire extinguishing
it is long shelf life material
it is low smoke and non-toxic when burning

May I know its application ?
UPGM203 laminate sheet performs well in electrical applications that require high arc and carbon track resistance as well as flame resistance, physical strength, and moderate heat resistance. UPGM203 laminate is used extensively in the making of phase and end barriers, insulating supports, bus bar supports and mounting panels in switch gear and other types of electrical apparatus. I will be more and more widely used in every electrical products as its very nice performance in insulation and strength.
