| description abstract | An unbranched perfluoropolyether is the current ball bearing lubricant for deep space flight. We report measurements of viscosity to moderate pressures for the calculation of pressure-viscosity coefficients to temperatures as low as −40°C. A free volume model predicts that a minimum pressure-viscosity coefficient exists at higher temperature. The existence of a minimum αo(T) is confirmed by viscometry at temperatures to 180°C. | |
