Title:
RUBBER VIBRATION DAMPENER COMPOSITION AND RUBBER VIBRATION DAMPENER
Document Type and Number:
WIPO Patent Application WO/2015/186482
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a rubber vibration dampener composition with which low temperature characteristics can be significantly improved while maintaining basic strength characteristics (hardness, tensile elongation, tensile strength), and a rubber vibration dampener obtained by curing said rubber composition. The present invention provides a rubber vibration dampener 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%.
