NEMA POLYESTER GRADES
B.I.R.S. Machine & Supply distributor of NEMA Polyester Grade sheet.
NEMA grades GPO-1 (tan color), GPO-2 (red color), GPO-3 (red color) Glass-Mat Reinforced Polyester - These grades are composted of random mat (non-woven) fiberglass reinforcement held together by a polyester resin binder. Polyesters are versatile resins which handle much like epoxies. Of course, the basic resins are chemically different. It's their physical application forms which make them similar. 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-2 offers superior arc resistance over GPO-1 while GPO-3 offers both arc and track resistance.
GPO-1 certifies to Mil-I-24768/4 GPO1
GPO-2 certifies to Mil-I-24768/5 GPO2
GPO-3 certifies to Mil-I-24768/6 GPO3
