FR4 epoxy boardThe main material is imported semi cured sheet, with colors including white, yellow, and green. It still has high mechanical strength at room temperature of 130 ℃, good electrical performance in dry and wet states, flame retardant, and is used for insulation structural components in industries such as electrical and electronics.
Synthesis: It is made by impregnating electrical alkali free glass fiber cloth with epoxy phenolic resin, baking, and hot pressing.
Performance: It has high mechanical and dielectric properties, good heat and moisture resistance, and good machinability, with a heat resistance level of B. Can be stamped.
FR4 epoxy boardIt is a mechanical device with a smooth surface, free from bubbles, wrinkles, and cracks. Due to its beautiful appearance and smooth surface, it is relatively easy to clean and maintain.
FR4 epoxy boardAt different temperatures, the performance varies. It has high mechanical performance at medium temperatures and stable electrical performance at high humidity. Due to its diverse forms, easy curing, strong adhesion, low shrinkage, and excellent mechanical properties, it is highly suitable for high insulation structural components in mechanical, electrical, and electronic applications.
Moreover, FR4 epoxy board has excellent corrosion resistance and stability, does not absorb moisture from the air, is not easily deformed, and has a long service life. Moreover, FR4 epoxy board is resistant to pollution and has a smooth surface, which can effectively inhibit bacterial growth, making it particularly suitable for pharmaceutical and biological laboratories.
