Effect of ENR on Physical and Damping Properties of Silica/NR Vulcanizate

The effect of ENR with different epoxidization degrees on the physical property,damping property and compression fatigue properties of silica/NR vulcanizates was investigated.The results showed that,ENR could improve the physical property and damping property in application temperature range,and decrease the compression fatigue temperature rise of silica/NR vulcanizates.It was found that when the epoxidization degree of ENR was 40%,the effect was the best.
