Abstract

The effects of the anti-reversion agent SR534 on the properties of NR compound were experimentally investigated and compared to those of anti-reversion agent PK900.The results showed that MH,scorch time and t90 of NR compound changed a little when the addition level of the anti-reversion agent SR534 was less than 2 phr;the reversion percentage of NR compound was decreased,the anti-reversion characteristic was improved as the addition level of the anti-reversion agent SR534 increased.The anti-reversion characteristic of SR534 was better than that of PK900 with the same addition amount;the anti-reversion agent SR534 and PK900 could be used to improve the physical properties of NR vulcanizate when the cure time was up to 60 min.
