| Abstract: |
| The application of naphthenic oil-extended SSBR in tread compounds was investigated.The results showed that，the tanδ of SSBR vulcanizate was higher at 0 ℃ and lower at 60 ℃ compared with those of NR vulcanizate，respectively.Therefore，application of SSBR in tread compounds could give the tire higher wet skid resistance and lower rolling resistance.Furthermore，SSBR had good compatibility with NR，and the comprehensive physical properties of SSBR/NR vulcanizate were good when SSBR/NR blending ratio was 20/80.With the addition of SSBR in tread compounds，the wet skid resistance，dry and ice grip of tire would be improved，and the rolling resistance would be reduced.It was recommended to use SSBR in high performance tire. |
