Bulk moulding compound

Bulk molding compound (BMC) or bulk molding composite is a ready to mold, glass-fiber reinforced thermoset polyester material primarily used in injection moulding and compression moulding. The material is provided in bulk or logs.

BMC is manufactured by mixing strands (>1”) of chopped glass fibers in a mixer with polyester resin. The glass fibers in BMC result in better strength properties than standard thermoplastic products. Typical applications include demanding electrical applications, corrosion resistant needs, appliance, automotive, and transit.
