摘要： An anti-vibration rubber composition includes the following components (A) to (C) and a sliding agent, wherein the sliding agent includes the following component (D), and wherein a content of the component (C) with respect to 100 parts by weight of the component (A) falls within a range of from 0.1 parts by weight to 10 parts by weight: (A) a diene rubber; (B) carbon black; (C) a white filler; and (D) an organopolysiloxane-modified polypropylene. The anti-vibration rubber composition can eliminate a reduction in sliding property due to a temperature environment or continuous use, and can effectively suppress an increase in frictional resistance against a mating member.

摘要： Provided is an anti-vibration rubber composition, including the following components (A) to (D), in which a ratio of the component (B) to a total content of the components (A) and (B) is from 5 wt. % to 20 wt. %: (A) A natural rubber, or a blended rubber of the natural rubber and a butadiene rubber; (B) A hydrogenated styrene-butadiene block copolymer; (C) A sulfur-based vulcanizing agent; (D) Zinc monomethacrylate. Thus, there can be provided an anti-vibration rubber composition and an anti-vibration rubber each of which is excellent in heat resistance, and has both a high damping property and a low dynamic-to-static modulus ratio.
