| Abstract: |
| The performance of standard formula compounds and winter tire tread compounds using domestic oil-extended neodymium-based butadiene rubber（NdBR） was investigated.The results showed that compared to imported NdBR，the physical and chemical properties of domestic oil-extended NdBR were generally comparable.When domestic oil-extended NdBR was used as an equivalent substitute for imported NdBR，the processability of the standard formula compounds and winter tire tread compounds remained similar，while the wear resistance improved and rolling resistance decreased. |
