Silicone rubber has excellent high temperature properties and can be used in liquid silicone injection molding or as a silicone gum in the compression molding process. Silicone rubber can operate normally from -55°C to +300°C. This makes silicone rubber components ideal in high altitude situations in the aerospace industry or high temperature sterilization environments (e.g. medical applications).
Silicone rubber is used in a variety of industries not only for its extreme temperature properties, but also the superiority to conventional rubbers in properties such as tensile strength, elongation, tear strength and compression set. Silicone rubber is a highly inert material and does not react with most chemicals. This makes it a highly used material in molding for medical applications and implants. Silicone rubber is an excellent electrical insulator and is often used in electrical connector insert applications.
Silicone rubber has a "backbone" of silicon-oxygen links as opposed to organic rubber that has a carbon to carbon backbone, which is a main factor in it's resistance to ozone, UV, heat and other aging factors.
