Antivibration rubber composition, and antivibration rubber

摘要

The present invention addresses the problem of providing: an antivibration rubber composition which can provide a hardened rubber product that has excellent antivibration properties (a low motion magnification), compression permanent strain and low-temperature properties and can keep strength properties (hardness, tensile elongation, tensile strength) and hot aging resistance thereof at good levels; and an antivibration rubber which is produced by hardening the rubber composition. An antivibration rubber composition characterized by comprising a rubber component, sulfur, a bismaleimide compound and N-phenyl-N-(trichloro-methylthio)benzenesulfoneamide, wherein the rubber component comprises a natural rubber and a polybutadiene rubber at a blend ratio of 60/40 to 90/10 by mass.
