## Abstract

The present invention makes public a type of car vibration damping products using high damping rubber compound materials, involving the rubber technical field, whose features are the following ones: chloride butyl, 100; carbon black N220, 10-40; carbon black N330, 20-50; naphthenic oil H-3107, 20-40; age resister RD, 1-3; age resister 4010NA, 1-3; homogenizing agent 40MSF, 3-6; indirect zinc oxide, 5-10; magnesium oxide, 0.1-0.5; accelerating agent BZ, 1-5. By the above deployed car vibration damping products which use high dumping rubber, you get excellent heat and age resisting properties, and also high dumping properties.
