| Abstract: | The influence of different curing systems,such as CV,SEV and EV on curing behavior,mechanical properties and heat aging properties of EPDM as well as antioxidant on its heat aging properties were investigated.The results showed that the EPDM cured with SEV or EV had better heat aging properties and that cured with CV had better mechanical properties;and antioxidant gave little effect on heat aging properties of EPDM. |
