GPO-3 material is not a plastic, but an insulating material.
GPO-3 insulation board, also known as GPO-3 laminate, is a hard plate-shaped insulating material made of alkali-free glass fiber felt board impregnated with unsaturated polyester resin paste and hot-pressed with corresponding additives. It has excellent electrical insulation, flame retardancy, arc resistance and resistance to leakage traces, and is suitable for the field of electrical engineering.
GPO-3 insulation board is widely used in the field of electrical engineering due to its excellent electrical and mechanical properties, especially in high humidity environment and medium temperature application .
