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.
Because FMC™ Polysulfide rubber is not inhibited by sulfur, original sculptures often done in a sulfur bearing modelling clay referred by sculptors (Roma Plastalina), FMC™ is perfect for casting foundry wax (lost wax process) and last a long time in mold libraries.
FMC™ Castable Polysulfide Mold Rubbers have been used for years to make tire pattern molds. They continue to be used today by Goodyear, Bridgestone, Firestone and other major tire manufacturers around the world.
