High-strength silicone rubber compositions.

摘要

Silicone rubber compositions, of the addition curable type, comprise as a base polymer a vinyl-containing organopolysiloxane having a tetraorganosilethylenesiloxane unit of the following general formula: <CHEM> wherein R<1> to R<4> are each a monovalent hydrocarbon group of from 1 to 10 carbon atoms. The silicone rubber composition gives a cured product having high strength, for example, a tensile strength of 30 kg/cm<2> or above, without compounding fillers or reinforcing agents.
