SMC and BMC are both thermoset composite materials made from a mixture of resin, reinforcement fibers (usually glass fiber), fillers, and additives. They are used in various industries, including automotive, electrical, and construction, due to their strength, durability, and design flexibility.
SMC (Sheet Molding Compound): A sheet-like material made by impregnating glass fibers (25-65% content) with resin, fillers, and additives. It is used in compression or injection molding processes to produce lightweight yet strong parts.
BMC (Bulk Molding Compound): A putty-like material with shorter fiber reinforcements (10-30% content), designed for injection or compression molding. It is more suitable for complex and high-precision parts.
