Sheet Molding Compound (SMC) is a ready-to-mold composite material in sheet form. It consists of SMC resin (unsaturated polyester resin), fillers, thickening agents, low-profile additives, and glass fiber reinforcement. This combination results in a high-strength, lightweight thermoset material ideal for producing complex and durable components through compression molding. https://www.reallandcomposite.com/sheet-molding-compound-suppliers-and-manufacturers-in-china.html
