Lubricants | Soy New Uses


Lubricants Motor Oil Renewable soybeans are a natural choice for product developers interested in promoting green chemistry. However researchers who Think Soy are finding added advantages of soy derivatives: Soybean oil provides a high viscosity index, enhanced lubricity, low volatility and low flammability Lifecycle assessment studies show using soybean oil as a raw material can help lower carbon dioxide emissions and energy costs during product production Soybean oil has good solubilizing power for contaminants, polar deposits and additive molecules compared with mineral-based fluids, reducing the need for detergent additives in formulated soybean-oil-based lubricants. New varieties of high oleic soybean oil are naturally more stable than traditional soybean oil, reducing the need for antioxidants and other expensive additives. High oleic soybean oil is also more economically modified into synthetic lubricant basestocks, which compete directly with polyalphaolefins and synthetic esters in lubricants. Reducing polyunsaturation through chemical or genetic modifications of soybeans results in improved oxidation stability. Chemical modification of soybean oil at the double-bond sites of the component fatty acids may also improve cold-flow properties.
