NP511 (NEMA G-11) combines a woven glass fabric and a high temperature epoxy resin system (Tg over 180°C) that is non-brominated. The product provides consistent quality and good electrical properties under dry and humid conditions, as well as high flexural, impact, and bond strength at room and elevated temperatures. This product is suitable for a variety of structural, high humidity, and electrical insulation applications, which include cryogenic applications and many other applications for which very high or very low temperatures are part of the environmental requirement of the application. NP511 meets or exceeds the requirements of MIL-I-24768/3, Type GEB.
