The main material of fr4 epoxy board is imported prepreg, the color is white, yellow, green, still has high mechanical strength at room temperature of 130 ℃, good electrical properties in dry and wet states, flame retardant, used in electrical, electronic and other industries Insulated structural components.
Synthesis: It is made of special alkali-free glass fiber cloth impregnated with epoxy phenolic resin, baked and hot pressed.
Properties: It has high mechanical and dielectric properties, good heat resistance and moisture resistance, and good machinability. The heat resistance grade is B. Stampable.
fr4 epoxy board is a machine whose surface should be smooth and free of bubbles, wrinkles and cracks. Because of its beautiful appearance and smooth surface, it is relatively easy to clean and maintain.
The fr4 epoxy board has different properties at different temperatures. It has high mechanical properties at medium temperature and stable electrical properties under high humidity. Due to its various forms, convenient curing, strong adhesion, low shrinkage and excellent mechanical properties, it is very suitable for high-insulation structural parts for machinery, electrical appliances and electronics.
Not only that, fr4 epoxy board also has super corrosion resistance and stability, will not absorb moisture in the air, is not easy to deform, and has a long service life. Moreover, the fr4 epoxy board is resistant to pollution and has a smooth surface, which can effectively inhibit the growth of bacteria, especially suitable for medical and biological laboratories.
