As a widely used material, epoxy boards are widely used in various circuits. Among them, we will talk about the more widely used 3240 epoxy board.
3240 epoxy board is a material made of electrical glass cloth impregnated with epoxy resin, dried and hot pressed. It is available in yellow, white and green. It has high mechanical strength at room temperature of 130℃ . Moreover, it has good electrical properties in dry and wet states, and is flame-retardant. It is used in parts of insulation structures in electrical and electronic industries. In addition, 3240 epoxy board has the following characteristics:
Synthesis: It is made by electrician special non-alkaline glass fiber cloth impregnated with epoxy phenolic resin, baked and hot pressed.
Thickness: 0.5～50mm under normal conditions, and 50～150mm thick plates can also be produced as required.
Performance: The mechanical and dielectric properties are relatively high, and the heat resistance and moisture resistance are good, and it has good machinability. The heat resistance grade is B grade and can be stamped. The cured epoxy resin system has excellent mechanical properties, high mechanical strength at medium temperature, and good electrical performance stability under high humidity.
Electrical properties: The cured epoxy resin system is an excellent insulating material with high dielectric properties, surface leakage resistance, and arc resistance.
Uses: For machinery, electronics, and electricity. It is suitable for mechanical, electrical, electronic, electrical and other fields. It is also used for insulating processed parts, or processed into various insulating parts, equipment insulating structural parts, etc.
