Abstract:
A vibration-damping rubber composition is provided, which is used as a material for a rubber member of a liquid-filled vibration-damping rubber device in which a glycol liquid is sealingly contained. The rubber composition comprises: (A) a chloroprene rubber as a major component; and (B) an aromatic hydrocarbon plasticizer. The rubber composition makes it possible to suppress increase in the hardness of the rubber member (chamber wall) after thermal aging and reduction in durability.
