Some examples

EPOGLASS G11 is the epoxy glass suitable for use with thermal stresses above 150°C. In fact, it is resistant to temperatures up to 180°C while maintaining high performance electro-mechanical and chemical resistance typical of epoxy glass. Compared to the FR4 type requires more attention in machining.
