| Abstract: |
| The effect of the addition level of anti scorching agent CTP on the crosslink density，filler network and physical properties of NR vulcanizates was investigated.The results showed that，as the addition level of CTP increased，the scorch time of NR compound extended significantly，and the filler network was strengthened.At the same time，the crosslink density of the vulcanizates decreased slightly， the loss factor increased，the modulus， tensile strength，tear strength and resilience tended to decrease， and the compression heat build up increased. When the addition level of CTP was 0.5 phr，the overall properties of NR compound were good. |
