Although it was observed that the amount of EVA in the blend significantly affected the overall performance of the vulcanizates, however the ENR/EVA-sulfur cured compounds generally exhibited better physico-mechanical than the DCP-cured samples. For example, the sample E (70 phr ENR/30 phr EVA-Sulfur cured) attained about 60% higher cure rate than the sample A (70 phr ENR/30 phr EVA-DCP cured). Also, the sample E exhibited an extreme fatigue life performance (~1.7 × 10<sup>4</sup> cycles at 15% strain) which was over 170 000% higher than sample A which obtained fatigue life of 10 cycles at the same strain. Again, the sample E obtained over 1200% tensile strength higher than the counterpart sample A. Even in an unfilled state, the sulfur-cured compounds (D and E) exhibited high physico-mechanical properties than the DCP-cured counterparts including related blends containing high reinforcements (30~50 phr) contained in literature.
