| Abstract: |
| The mechanical properties，heat aging properties and oil resistance of ECO/NBR-26，ECO/NBR-33 and ECO/NBR-41 with different blending ratios were investigated.The results showed that the tensile strength and elongation at break of the blend changed little when 10～40 phr of NBR-26，NBR-33 or NBR-41 were used；the volume swell of the blend vulcanizate in oil，particularly in oil at 100 ℃ increased as the proportion of NBR-26 or NBR-33 in the blend increased；and the volume swell of the blend vulcanizate in oil at 100 ℃ decreased significantly as the proportion of NBR-41 in the blend increased. |
