Red GPO3 Fiberglass Sheet machined parts have UL certification high flexture strength
GPO3 laminate sheet aslo known as UPGM 203, it is alkali-free fiberglass mat dipped into unsaturated polyester resin adding relevant chemical agent as the basic material pressed under high temperature molded 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 is applicable for making insulation structure components or parts in F-class electric motors,transformer,switchgear,circuit breakers and electrical equipments. UPGM can be moulded into all kinds of structure parts or profiles as per customer's special requirement.
