VIBRATION-PROOF RUBBER COMPOSITION AND LIQUID-ENCAPSULATION TYPE VIBRATION-PROOF DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a vibration-proof rubber composition capable of controlling rising of hardness of rubber member (chamber wall) and decreasing of durability after heat aging.SOLUTION: A vibration-proof rubber composition is used for a rubber member of a liquid-encapsulation type vibration-proof rubber device where a glycol-based liquid is enclosed, which is a vibration-proof rubber composition comprising (A) chloroprene rubber as a main component and (B) an aromatic-based plasticizer.
