Mechanical and Oil Resistance Characteristics of Rubber Blends Based on Nitrile Butadiene Rubber

摘要

Different rubber blends based on nitrile butadiene rubber, NBR (N3980-39% acrylonitrile) have been prepared to get a product with high oil resistant and good mechanical properties. The obtained mixes included NBR, chloro-prene rubber (CR) and polyvinyl Chloride (PVC). The ratio of each component (NBR, CR and PVC) as binary or ternary blend system has been varied and the corresponding vulcanizing Systems have been carefully selected. It has been found that the type of rubber and the composition of blends markedly affect their oil resistance. In contrast, the type of crosslinks and crosslinking density slightly affect the oil resistance of the corresponding vulcanizates.
