Abstract
The present invention addresses the problem of providing a rubber vibration isolator composition with which low temperature characteristics can be significantly improved while maintaining basic strength characteristics (hardness, tensile elongation, tensile strength), and a rubber vibration isolator obtained by curing said rubber composition. The present invention provides a rubber vibration isolator composition characterized in containing natural rubber, a high cis content isoprene rubber, a crosslinking agent and an aromatic sulfonamide having a specified chemical structure. The high cis content isoprene rubber refers to the cis-1,4 bond content being at least 95%.
