RUBBER COMPOSITION FOR ANTI-VIBRATION RUBBER AND AN ANTI-VIBRATION RUBBER

The present invention provides a rubber composition for anti-vibration rubber which can achieve a balance of a low dynamic magnification and a high dampening property when it is made into an anti-vibration rubber, as well as provides an anti-vibration rubber obtained from the rubber composition for anti-vibration rubber as a raw material. The object can be solved by a rubber composition for anti-vibration rubber, including: when a rubber component included in the rubber composition is assumed to be 100 parts by mass, 10 to 30 parts by mass of a polystyrene butadiene rubber; and 40 to 00 parts by mass of at least one kind selected from the group consisting of a natural rubber and a polyisoprene rubber. It is preferable to provide an anti-vibration rubber formed through vulcanization of the rubber composition for anti-vibration rubber, and that it has a peak of tan δ at 10° C. or more.
