摘要
Low specific gravity silicone rubber composition that possesses excellent dimensional stability during moulding as well as during heating and cooling after curing. The silicone rubber composition comprises a diorganopolysiloxane having a viscosity of from 100 to 100,000 mPa.s which preferably comprises at least two alkenyl groups per molecule, a hydrophobic reinforcement silica filler; a curing agent in an amount sufficient to cure the composition, hollow resin particles consisting of external shells made of a non-silicone thermoplastic resin, and gaseous or volatile-liquid cores; and water. It is preferred that the curing agent is an addition cure agent.
