This two kinds of thermosetting industrial Laminate(G11 / EPGC203
and FR5 / EPGC204) are electrical alkali-free glass woven fabric
base impregnated an epoxy resin binder by processing under
pressure and heat, G11 is similar to G10 and FR5 to FR4, with the
addition of a higher operating temperature and some improved
mechanical strength at elevated temperature. It is widely used as
all kinds of insulation components.
