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.
Silicone is known for its retention of flexibility and low compression set in extreme heat or cold. Silicone rubber is very durable and overall, has good mechanical properties. Because of its durability, it is extremely reliable and can be trusted to keep up performance for a long time.
