NR/EPDM co-cured rubber blends with sulfur and organic peroxide used together as the co-curing agents to achieve ozone resistant, high tensile property rubber compositions. Sulfur accelerators MBTS and DPG are also employed in the curing process. NR/EPDM blends of from 70/30 to 55/45 are cured in an air cure process with sulfur in the range of 0.64-1.6 phr and with organic peroxide in the range of 0.6-1.6 phr.
