It (NEMA G-10) is a thermoset rolled and molded composite consisting of a medium-heavy weave glass fabric reinforcement combined with a high-temperature epoxy resin system. The properties of this composite material are similar to those of NEMA G-11 and MIL-I-24768/3; however, rods are not a recognized form by either specification. RM511A provides high electrical and mechanical strength at elevated temperatures of 150°C and above. RM511A is suitable for inserts, bushings, cams, rings, collars, spacers, plugs, dowels, insulators, timing wheels, and light-duty gears.
