| Abstract: |
| The application of self-made liquid isoprene rubber（LIR） in the shoulder compound of tire was investigated，and compared with aromatic oil and imported LIR.The results showed that，when compared with compound containing aromatic oil，the mixing behavior and extrudability of compound containing LIR were better，the scorchtime was slightly shortened，the curing rate was similar，the tear strength was lower，other physical properties were better or similar，the heat build-up was lower，and the thermal stability was better，The performance of self-made LIR in shoulder compound met or exceeded the level of imported LIR in the shoulder compound. |
