BMC is the abbreviation of Bulk Molding Compound (bulk plastic), which is often called resin glass fiber reinforced plastic in China. Its main raw material is a dough-like prepreg that is fully mixed with GF (chopped glass fiber), UP (unsaturated resin), MD (filler calcium carbonate) and various additives. Various inert fillers, fiber reinforcements, catalysts, stabilizers, and pigments are mixed to form an adhesive “putty-like” composite material for compression molding or injection molding. Bulk molding compound (BMC) is highly filled and reinforced by short fibers. Glass fiber reinforced material accounts for 10% to 30%, and the length is usually between 1/32 inch and 1/2 inch (12.5mm). Commonly used in electrical parts (insulators, meter boxes, circuit breaker shells, terminal blocks, various household or commercial electromechanical product shells), auto parts (front lamp reflective surfaces, rear doors, speaker shells, etc.), meter shells , Audio equipment housing, etc.
