GPO-3 is alkali-free fiberglass mat dipped into unsaturated polyester resin adding relevant chemical agent as the basic material pressed under high temperature into rigid panel insulating material.
It is also called as UPGM203 and suitable for mechanical and electrical usage.
GPO-3 has good electrical property under high humidity and high mechanical property under medium temperature, fire retardant property, good arc resistance and tracking resistance.
Its widely used in the low voltage electrical industry in the European and American countries.
