Epoxy Glass Cloth Laminate Sheet (NEMA G10/FR4)

Nema G10 FR4 sheet, EPGC201 EPGC202

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.
