| The influence of flowing and dispersing agent RL20,WB42 and AC617 on the properties of EPDM compound was investigated.The results showed that,in terms of improving compound flowability,RL20 and WB42 were better than AC617,and the filler dispersion was improved by adding RL20 and WB42,while AC617 had no significant effect.All three flowing and dispersing agents had little effect on the curing behavior,physical properties and thermal aging property of compound.It was found that the compression set of vulcanizate with RL20 and WB42 was slightly decreased,but the compression set of vulcanizate with AC617 was slightly increased. |
