Impact Resistant 50mm NEMA Grade GPO3 Fiberglass Sheet

NEMA grade GPO-3 glass fiber mat with EN45545 and UL certificate



What is GPO-3 material ?


GPO-3 Sheet is laminated sheet , it is also known as UPGM203 sheet . It is alkali-free fiberglass mat dipped into unsaturated polyester resin and adding aluminium hydroxide as the basic material , then pressed under high temperature into rigid panel as insulating material. It has good electrical property under high humidity and high mechanical property when running in the electrical equipment . It has fine fire retardant property, good arc resistance and tracking resistance. It's widely used in the low voltage and medium voltage electrical industries .
