Product Introduction
SMC sheets are a high-performance composite material made from unsaturated polyester resin as the matrix resin, with the addition of fillers, reinforcing fibers (usually glass fibers), hardeners, release agents, and other auxiliary materials, formed under high temperature and pressure. SMC sheets are widely used across various fields due to their exceptional insulation performance, high strength, lightweight, corrosion resistance, fire retardancy, and long-lasting durability, especially in the power and electronics industries for manufacturing various insulation components and structural parts.
