G10/FR-4 Glass Epoxy

Glass/epoxy composite material with outstanding electrical properties

G10/FR-4 is a composite material that consists of glass fabric, electrical grade epoxy resin. The material is extremely strong and stiff, has a low coefficient of thermal expansion, and outstanding electrical properties. G10/FR-4 is widely used as an insulator for electrical and electronic applications. It is also used for mechanical applications when outstanding strength, stiffness, and excellent creep resistance are required.
