High Quality Glass Fiber Chopped Strands For BMC ( Bulk Molding Compound)

Manufacturer's High Quality Glass Fiber Chopped Strands For BMC ( Bulk Molding 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 a thermoset resin (commonly polyester resin, vinyl ester or epoxy 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.

Glass fiber chopped strands for BMC mixed with unsaturated polyester paste. Suitable for the mold molding, transfer molding and injection molding technology, products of good mechanical performance, high dimensional stability and good surface finish, good water resistance, oil resistance, corrosion resistance, heat resistance, excellent electric properties, especially the arc resistance can reach about 190 s. Resin sizing agent in formula, the main ingredients with the sheet molding compound, packing, generally without thickening agent, then resin sizing agent and chopped glass fiber length (about 3 ~ 25 mm) fully mixing system. Mainly used in electrical, motor, radio, instrument, machinery manufacturing, chemical equipment, construction, transportation, defense and other departments.
