Epoxy Board FR4/3240 Processing As a Widely Used Material
Epoxy board processing is widely used in various circuits as a widely used material. Among them, it has been widely used to talk about 3240 epoxy board. It is a material made of electrician and epoxy glass cloth, drying and hot pressing machine. It is yellow, white, green, 130 ° C, and has high mechanical strength at normal temperature. , and electrical characteristics in a dry and humid state is very good, flame retardant, used for some of the insulation structure in the electrical and electronic industries. In addition, the 3240 epoxy board has the following features:
Synthesis: Non-alkali glass fiber cloth impregnated with electric epoxy phenolic resin is baked and hot pressed.
Thickness: generally 0.5 ~ 50mm, can also produce 50 ~ 150mm thick plate as required.
Performance: The mechanical properties and dielectric properties are relatively high, and the heat resistance and moisture resistance are good, and the mechanical processing performance is good. The heat resistance grade is B grade and can be stamped. The post-cured epoxy resin system has excellent mechanical properties, and the temperature is high in the plane, and the high-humidity electrical property is stable.
Electrical properties: The cured epoxy resin system is an excellent insulating material with high dielectric properties, resistance to surface leakage and arc resistance.
Uses: machinery, electronics, electrical appliances. Suitable for mechanical, electrical, electronic, electrical and other fields. It can also be used for insulation processing or processing into various insulation parts and equipment insulation structural parts.
