| Abstract: |
| The effect of the addition level of sulfur，antioxidant 4010NA，accelerator TMTD，accelerator NS，plasticizer A on the tensile strength，elongation at break and its retention，compression set of EPDM vulcanizate for sealing ring was investigated by using orthogonal experiment design method. The results showed that，the addition level of sulfur was the most significant factor.When the addition level of sulfur，antioxidant 4010NA，accelerator TMTD，accelerator NS and plasticizer A was 0.5，2，1.5，1 and 2 phr respectively，the permanent compression deformation resistance was the best. |
