Epoxy Glass Cloth Laminate Sheet (NEMA G11/FR5)

Nema G11 FR5, EPGC203 EPGC204

Properties

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.
