BMC, the full name of Bulk Molding Compound, is a thermosetting fiber-reinforced composite material. It is made by thoroughly compoundinged polyester resin with chopped glass fibers, inorganic fillers, low-shrinkage additives, curing agents, and various functional additives using specialized equipment. It appears as a uniforty-like prepreg and serves as a core semi-finished base material in the industrial molding field.

This material combines excellent electrical insulation, mechanical strength, heat resistance, flame ret dimensional stability. It features an extremely low molding shrinkage rate and superior flowability, making it compatible with automated molding processes such as compression molding and injection molding. It enables thestep molding of complex and precision parts, offers strong batch consistency, and can be customized for color and performance specifications. Widely used in electrical and electronic, automotive, new enerrail transit industries, it is the preferred base material for insulating structural components, functional enclosures, and precision industrial accessories.
