BMC/SMC raw material uses Alita’s unsaturated polyester resin.

Sheet & Bulk Molding Compounds

Bulk Molding Compounds (BMC) and Sheet Molding Compounds (SMC) are both fiber reinforced materials, typically utilizing glass strand fibers of varying lengths. SMC uses slightly longer length fibers than BMC, and typically has a higher percentage of reinforcement fibers than BMC. Fiber Lengths range from 1/32-inch in BMC up to 1-inch in some SMC’s, resulting in various strength characteristics which can be customized for individual needs.
