PROBLEM TO BE SOLVED: To provide a vibrationproof rubber composition capable of largely improving low temperature property while maintaining functional properties of strength properties (hardness, tensile elongation and tensile strength), and a vibrationproof rubber manufactured by curing the rubber composition.SOLUTION: There is provided a vibrationproof rubber composition containing a natural rubber, an isoprene rubber, a crosslinking agent and aromatic sulfonamides and the isoprene rubber is a mixture of high-trance-content isoprene rubber having 95% or more of a trans-1,4-bond content and high-cis-content isoprene rubber having 95% or more of a cis-1,4-bond content. |
