Can you pls introduce about UPGM203 material ?
Yes , UPGM 203 laminate material also known as GPO-3 material, UPGM203 is IEC standard and GPO-3 is NEMA grade , different standard with different name .UPGM203 is widely used in Europe and GPO-3 used in North America .This material is alkali-free fiberglass mat Impegnateed into unsaturated polyester resin added relevant chemical filling material as the basic material pressed under high temperature press into rigid panel as insulating material. It has good electrical property under high humidity ,mechanical property under medium temperature, very nice on fire retardant property (it meet UL94-V0), 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 ,UPS and other types of electrical apparatus.

May I have the feature of UPGM203 ?
This material is the environmental protection material which meet RoHs , Reach and halogen-free requirement ;
it is halogen-free but flame retardant meet UL94-V0, it has the property on fire extinguishing
it is long shelf life material , it with 10 years expiration date
it is low smoke and non-toxic when burning and suited in place of concentration
What is the application of this material ?
We are one of the most biggest UPGM203 manufacturer in China , laminate sheet and shapes were produced by our production line , so the material cost , quality and lead time can be controlled .
UPGM203 laminate sheet performs well in electrical applications that requires 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. It will be more and more widely used in every electrical products as its very nice performance in insulation and strength . Actually , more and more electric products required excellent property of electric such as cti and track resistance , GPO-3 meets these requirement .
