Silicone moulding (molding) is a manufacturing technique used to transform uncured (unvulcanized) silicone rubber into a pre-defined shape. Several moulding techniques may be used, including compression, injection, and liquid injection. Platinum catalyst silicone molds (like our Food Grade silicone or silicone putty) last 20+ years when stored properly. Latex molds last 10-20 years when stored properly. Urethane rubber molds (like our 75A urethane rubber) last 20+ years when stored properly.
