| Abstract: |
| The influence of pre-treated PPTA-pulp on the properties of NBR compound was investigated.The results showed that，as the addition level of PPTA-pulp increased，the scorch time of NBR compound tended to shorten，the MH increased gradually，the hardness and modulus at 50% elongation of the vulcanizates increased，the elongation at break decreased，the tear strength increased at first and then decreased，the oil resistance was improved，and the shear storage modulus increased.The thermal stability of the vulcanizates with PPTA-pulp was better than that without PPTA-pulp.The pre-treated PPTA-pulp was uniformly dispersed in NBR. |
