Bulk Molding Compound: An Engineered Thermoplastic Composites Material Bulk molding compound, commonly known as BMC, is an engineered thermoplastic composites material predominantly used in compression and injection molding applications. It consists of fiber reinforcement, typically short glass fibers, embedded in a non-crosslinked thermosetting polymer matrix. The polymer matrix is typically made from unsaturated polyester or vinyl ester resin. Composition and Manufacturing Process of BMC BMC consists of 30-70% by weight of fiber reinforcement and the remaining polymer resin matrix. The short glass fibers used have a length ranging from 0.25-1 inch. Along with glass fibers, carbon and Kevlar fibers are also sometimes used. The polymer resins used are unsaturated polyester or vinyl ester due to their ability to readily wet out and bond to glass fibers.
