Interpretive Summary:

Technical Abstract: Heat-bodied oils are biobased oils obtained via thermal treatment of vegetable oils under inert (N2) atmospheric conditions. Most heat-bodied oils are based on soybean oil, but other vegetable oils and blends of vegetable oils can also be utilized to obtain specific properties. Depending on the temperature and duration of the thermal treatment, various viscosity grades of high molecular weight heat-bodied oils can be produced. In this work, a series of soybean based heat-bodied oils of wide range viscosity grades (68–1250 mPa's at 40°C) were synthesized and their elastohydrodynamic properties investigated. The effect of heat-bodied oil structures on density, viscosity, viscosity index, film thickness, and pressure viscosity coefficients will be discussed.
