If you need properties that are different than the ones in the chart below please take a look at our other popular rubber material specifications otherwise we can compound and reformulate the silicone rubber specifications to. Silicon does not occur as a single element in nature. Silicone rubber material specifications.

Silicone is a synthetic rubber elastomer where the principal raw material is silicon si which is the second most abundant element in the earth s crust following oxygen. This specification covers a silicone rubber material that can be used to manufacture product in the form of sheet strip tubing extrusions and molded shapes. Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.

This specification should not be used to address products such as o rings compression seals o ring cord and molded in place gaskets. This specification provides material requirements and testing procedures to differentiate between the physical mechanical electrical and adhesive bonding properties of three types of rtv silicone rubber compounds.
