FMC™ Series
Polysulfide Mold Rubber
FMC™ rubber molds are very durable and will last for years in production casting of wax or gypsum. Ideal for those applications that require capturing intricate detail from a variety of model surfaces. Unlike polyurethanes, FMC™ is not sensitive to moisture or sulfur and can be poured directly over wet plaster or water/sulfur based clays. Common applications include molds for foundry and pattern work, sculpture (lost wax process) and casting architectural gypsum pieces.
