An anti-vibration rubber composition and an anti-vibration rubber product having excellent balance between dynamic characteristics and mechanical strength, fatigue resistance, heat resistance and weather resistance are provided. (A) An ethylene / C3-C20 α-olefin / non-conjugated polyene copolymer satisfying the following (1) to (3) (1) Unit derived from a specific amount of ethylene (2 ) Unit derived from a specific amount of non-conjugated polyene (3) B value = ([EX] +2 [Y]) / 2 × [E] × ([X] + [Y])) 1.05 or less (B) Specific amount of finely divided silicic acid and / or silicate (C) having a specific surface area of 5 to 500 m 2 / g Specific amount of α, β-unsaturated carboxylic acid metal salt (D) specific amount It is based on the composition characterized by including the organic peroxide of this. However, [E], [X], and [Y] are the mole fractions of ethylene, α-olefin, and non-conjugated polyene, respectively, and [EX] is the dyad chain fraction of ethylene / α-olefin. [Selection figure] None |
