This specification should not be used to address products such as o rings compression seals o ring cord and molded in place gaskets.

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. 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. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. 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.

The silicone properties that are listed below are for our most popular silicone 70 durometer 70a rubber material. This specification covers a two part flowable space grade silicone rubber room temperature vulcanizing rtv adhesive or compound. 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.
