Epoxy Glass Cloth Laminate Sheet (NEMA G10/FR4)
Properties
This two kinds of thermosetting industrial Laminates (G10 / EPGC201 and FR4 / EPGC202) are electrical alkali-free glass woven fabric base impregnated an epoxy resin binder by processing under pressure and heat, which have extremely high mechanical strength, good dielectric loss properties and good electric strength properties. In addition, FR4 sheet has anti-fire property than G10 sheet.
