Effect of Formulation on Mechanical Properties and Oil Resistance of NBR Compounds

NBR Compounds with different formulations (filler, oil and other additives) were prepared and compression moulded at 160C. The effect of formulation on the mechanical properties, oil resistance and oil sorption mechanism in motor oil for 72 h at 150^C were investigated. In this research we sought to design a formulation based on NBR for automotive applications. The result show that using a blend of silica and carbon black is better than a silica or car-bon black alone to achieve optimum mechanical properties and oil resistance. NBR Vulcanizates containing mineral aromatic oil have better mechanical properties and oil resistance than vulcanizates containing dioctyl phthalate.
