Uphawu oluphambili lwe-EPDM yikhono layo eliphezulu lokuxhathisa i-oxidation, i-ozone kunye nokukhukuliseka.Ngenxa yokuba irabha ye-ethylpropylene ye-polyene (PA66) yosapho lwe-hydrocarbon, ineempawu ezigqwesileyo ze-vulcanization.Kuyo yonke irabha, i-EPDM inowona mxhuzulane uphantsi.Iyakwazi ukufunxa ezininzi iifayili kunye neoli enefuthe elincinci kwiipropati.Ngoko ke unokwenza iikhompawundi zerabha ezinexabiso eliphantsi.
