Product Introduction
FR4 Epoxy Fiberglass Sheet (EPGC 202/NEMA FR4/HGW2372.1) is also called FR-4 flame retardant epoxy fiberglass sheet ,It is a laminated product made of electronic grade glass fiber cloth impregnated with epoxy resin and flame retardant and pressed under high temperature and high pressure.
FR4 Epoxy Fiberglass Sheet has excellent mechanical properties, dielectric properties, and thermal stability. It is suitable for insulating structural parts of electrical equipment, electronic equipment, and mechanical processing.
FR4 Sheet Type:FR4 epoxy sheet / ESD FR4 sheet / Halogen-free FR4 sheet. The main differences are:ESD FR4 is a controlled anti-static Sheet, while halogen-free FR4 is an environmentally friendly flame-retardant sheet that complies with regulatory requirements.
