| The effect of peroxide type,addition level of curing agent DCP and secondary curing agent TAIC,and different curing agents on the properties of FKM was investigated.The results showed that,the comprehensive physical properties of FKM cured by DCP were better than those cured by peroxide BIPB,DBPMH,DCBP and BPO,and the compression set was lower.As the addition level of DCP increased,the compression set of FKM decreased.With 3 phr of DCP,the physical properties of FKM with low compression set were better.When the addition level of TAIC increased,the compression set of FKM decreased,and the optimized level was 5 phr.The resistance to compression set of FKM cured by DCP was better than that cured by 3# curing agent,but worse than that cured by bisphenol AF/BPP. |
