MC511A (NEMA G-11) is a high performance thermoset epoxy fiberglass composite that provides excellent physical, mechanical, and electrical properties at both room temperature and elevated temperatures. In use, the product is often exposed to continuous temperatures as high as 155°C for up to a decade. And in short-term applications such as insulation in aerospace and defense systems, the material withstands temperatures in excess of 300°C. Halogen free to conform to European restrictions, MC511A is specially formulated to meet exacting power generation standards requiring higher strength at elevated temperatures. The product is considered the premier material for use as Class F insulation in electrical power generation and transmission equipment. MC511A complies with the requirements of MIL-I-24768/3, Type GEB.
