Abstract : In both civilian and military systems the demand for lubricants exhibiting superior performance characteristics over a wide temperature range has increased dramatically since World War II. Neopentyl polyol esters introduced in the 1960s are a group of synthetic lubricants which meet these requirements. These esters exhibit very good thermal and oxidative stability at high temperatures ( 200 degrees C), excellent viscosity-temperature characteristics, and low pour and freeze points (-55 degrees C). Consequently, for adequate performance at high temperatures (220 degrees C), the neopentyl polyol esters have replaced the petroleum based fluids and the diesters, which were used prior to the 1940s and 1950s, respectively.
