| Abstract: |
| The effect of the addition levels of zinc dimethacrylate [Zn(MAA)2] and DCP on the properties of peroxide-cured EPDM was investigated.The test results showed that the curing rate and curing degree of EPDM increased significantly without affecting its viscosity as the addition level of Zn(MAA)2 in EPDM compound increased；and at the same time the Shore A hardness of EPDM vulcanizate increased gradually and its tensile strength and elongation at break increased at first，and then decreased.The optimum comprehensive properties of EPDM vulcanizate were obtained when 1 phr of DCP was used.The reinforcing effect of zinc salt was relative to the intrinsic properties of EPDM，and high proportions of ethylene and diene were favorable for good Mechanical properties of EPDM vulcanizate. |
