Product Overview

Key Specifications

BMC is a bulk molding compound mainly made of chopped glass fiber, resin, filler, and functional additives. It is suitable for applications that require insulation, heat resistance, dimensional stability, and efficient molding of complex shapes.

For buyers who need stable processing, small and complex geometries, production efficiency, and long-term consistency, BMC is a mature composite solution that balances functional performance and molding efficiency.
