<p><P>PROBLEM TO BE SOLVED: To provide a vibration-proof rubber excellent in a dynamic-to-static modulus ratio and compression set properties, and in particular, suitably usable in a high temperature environment such as an engine room of an automobile. <P>SOLUTION: The vibration-proof rubber composition includes, as a rubber component: a natural rubber (NR); an ethylene-propylene-diene rubber (EPDM); and a terminal-modified butadiene rubber (terminal-modified BR) at a mass ratio (NR)/(EPDM)/(terminal-modified BR) of 45-65/30-45/5-20, and contains a peroxide as a vulcanizing agent and a zinc acrylate and/or a zinc methacrylate as a co-crosslinking agent. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
