Nema Grade

Glass Reinforced Polyster GPO-3 offers superior arc and track resistance. GPO-3 (red color) Glass-Mat Reinforced Polyester is a random mat (non-woven) fiberglass reinforcement held together by a polyester resin

binder. Polyesters are versatile resins which handle much like epoxies. GPO-3 is a UL recognized grade and is highly flame retardant and low-smoke generating.temperature, Index of 120 degrees celsius electrical and 140 degrees celsius mechanical, Despite lower costs, the important disadvantages of polyesters, as compared with epoxies, is lower adhesion to most substrates, higher polymerization shrinkage, a greater tendency to crack during cure or in thermal shock and greater change of electrical properties in a humid environment. GPO-3 offers both arc and track resistance. GPO-3 certifies to Mil-I-24768/6 GPO3).
