Questions about Thermoset Composites?

STC®

Structural Thermoset Composites
Structural thermosets are high-performance composites that are distinguished from standard compounds by the use of more specialized resins both liquid and solid (vinylester, epoxy, benzoxazine, etc.) combined with higher levels of reinforcement (glass, carbon, natural, etc.).

SMC

Sheet Molding Compounds
SMC is a combination of long chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a malleable sheet material. Processing of SMC of is typically done by compression or injection molding.

BMC

Bulk Molding Compounds
BMC is a combination of short chopped glass strands, mineral fillers and liquid thermosetting resin in the form of a bulk material. BMC is suitable for either compression or injection molding.
