This includes the mutually interacting influence of base oil polarity and thickening agents on the rheologically-measured mechanical structural degradation in transient shear flow. Due to the high temperature dependence of Keesom forces in the background of polar-active bond mechanisms, the analysis of the transient flow response as a function of temperature allows to attribute the observed influences to differences in base oil polarity. In general, clay-thickened greases show a greater tendency to be rheologically influenced by base oil polarities than soap-thickened lubricating greases.}, publisher = {MDPI}, title = {Influence of Base Oil Polarity on the Transient Shear Flow of Biodegradable Lubricating Greases}, doi = {10.3390/lubricants3030611}, author = {Fiedler, Martin and Sánchez Martínez, Rubén and Valencia Barragán, Concepción and Leopold, Claudia S. and Kuhn, Erik and Franco Gómez, José María}, }
