| The influence of processing aid RL16,WB16 and AC617 on the properties of CR compound was investigated.The results showed that,when processing aid RL16（or WB16）was blended with anti-scorching agent DM,the curing rate,scorch safety and processing safety of CR compound were improved.The scorch safety of CR compound with processing aid AC617 had little change.In addition,three processing aids had little effect on the physical properties of CR vulcanizate. |
