The letter G means glass fiber. 10 means the content of fiber glass is 10%. G10 epoxy board is made of glass fiber cloth and epoxy resin that equipped with mechanical strength and is not out of shape easily. It also has good insulation and acid and alkali resistance. G10 has good insulation strength, chemical resistance, radiation resistance and thermal shock resistance. Good tensile strength, flexural strength and low temperature adaptability. There are usually black, red, blue, green and other colors.
FR4 precisely should be called FR – 4 epoxy board. Its raw material is imported electronic glass fiber cloth which is a kind of suitable for application in high performance electronic insulation requirements of products, comprehensive performance and flame retardant, halogen free accord with the EU standards, so the material application is very widely which can be used in all sorts of plank of reinforcement, motor, electrical equipment insulation structure parts. FR4 epoxy glass fiber board main material is half cured, color is white, yellow, green .High mechanical strength normal temperature of 150 ℃. Dry condition, wet condition electrical performance, flame retardant, used for electrical, electronic and other industries insulation structure parts. The main specifications are 1020*1220mm.
