What is Rubber?
Rubber is a polymer which can stretch and shrink. It occurs naturally and can be synthesized as well. We have been using rubber products since ancient times. But during the 19th century it became a highly useful industrial raw product for various purposes.
Types of Rubber
Rubber can be divided into following two types based on its origin –
Natural Rubber
Synthetic Rubber
There is a wide variety of synthetic rubber available such as EPDM (Ethylene Propylene Diene Monomer) rubber, commercial black rubber, SBR (Styrene butadiene rubber), NBR (nitrile butadiene rubber), IIR (Isobutylene-isoprene) etc.
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.
