Bulk moulding compound
Encyclopedia
Bulk moulding compound or bulk molding composite is a ready to mold, 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.
Fiber
Fiber is a class of materials that are continuous filaments or are in discrete elongated pieces, similar to lengths of thread.They are very important in the biology of both plants and animals, for holding tissues together....

Polyester
Polyester is a category of polymers which contain the ester functional group in their main chain. Although there are many polyesters, the term "polyester" as a specific material most commonly refers to polyethylene terephthalate...

Injection moulding
Injection molding is a manufacturing process for producing parts from both thermoplastic and thermosetting plastic materials. Material is fed into a heated barrel, mixed, and forced into a mold cavity where it cools and hardens to the configuration of the cavity...
