| Abstract: |
| The influence of carbon black N330/N990 blending ratio on the properties of EPDM compound for high speed railway pad was studied.The results showed that，when 20phr of N330 in the original formulation was replaced by an equal weight of N990，the Mooney viscosity of the compound decreased by 15 units and the temperature rise in the compression fatigue test was lowered by 6 ℃.With increasing the addition level of N990，the resilience and fatigue resistance of the vulcanizates were improved，and the compression set decreased. |
