OUR PRODUCTS
Sheet Moulding Compound and Bulk Moulding Compound (or Dough Moulding Compound) are part of the so-called thermosetting materials, for which there is no softening point: for SMC, BMC and DMC the cross-linking between resin and solvent leads to an irreversible hardening. SMC comes in the form of a mat welded in boxes or wrapped on rolls, while BMC and DMC are in raw form: a pasty material packed in bags.

BMC & SMC Compounds Portfolio
SMC
Sheet Moulding Compound is a sheet material composed primarily of polyester resin, mineral fillers and glass fibers. Resin, fillers, and additives are mixed together resulting in a paste of honey-like consistency, which is then pumped into an “impregnating” machine equipped with a cutter that adds the reinforcing fiber in a predetermined and constant amount.


BMC
Bulk Moulding Compound is a material that appears as a homogeneous mass, composed mainly of polyester resin, mineral fillers and glass fibers. The polyester resin and additives are first mixed, then the resulting paste is transferred to a kneading machine where the mineral fillers and chopped (pre-cut) fiberglass, typically 6 or 12 mm in length, are then added.
