SMC and BMC are abbreviations of respectively Sheet Molding Compound and Bulk Molding Compound. SMC and BMC form a family of structural, fiber reinforces thermosetting resins. SMC and BMC are intermediate materials from which a large variety of products can be manufactured by compression molding or injection molding. Base materials of SMC and BMC are, generally spoken, unsaturated polyester resins, glass and mineral filler materials, such as chalk or aluminum trihydrate. The composition of the compounds can be adapted to the application where it is used for. Specific properties such as flame retardancy, surface quality and paintability can be achieved by adding specific, functional materials. SMC and BMC product are used in a very broad range of applications.
