| Abstract: |
| The effect of the blending ratio of millable polyether polyurethane（MPU）and NBR on the properties of MPU/NBR blend was investigated.The results showed that，as the addition level of NBR increased，the MH of the compound increased，t90 was extended，and curing rate decreased.With more NBR，the crosslinking density of the vulcanizate increased，permanent compression set decreased，thermal stability and low temperature resistance were improved，ozone aging resistance decreased，and oil resistance changed little. |
