摘要： An ashless hydraulic fluid or paper machine oil having a Vl between 155 and 300, a RPVOT greater than 680 minutes, and a kinematic viscosity at 40°C from 19.8 cSt to 748 cSt. An ashless hydraulic fluid or paper machine oil having a high Vl and high RPVOT comprising: a) a Group III base oil with a sequential number of carbon atoms, and defined cycloparaffin composition or low traction coefficient, b) an ashless antioxidant additive concentrate, and c) low amount of Vl improver. A process for making an ashless hydraulic fluid or paper machine oil comprising a) hydroisomerization dewaxing, b) fractionating, c) selecting a fraction having a very high Vl, and a high level of molecules with cycloparaffinic functionality or a low traction coefficient, and d) blending the fraction with an ashless antioxidant. Also, a method of improving the oxidation stability of an ashless hydraulic fluid or paper machine oil.

摘要： Disclosed are phosphate ester base fluids and aircraft hydraulic fluids containing a novel combination of phosphate ester components. The disclosed aircraft hydraulic fluids contain from about 30 to about 45 weight percent, based on the total weight of the fluid, of tri-iso-butyl phosphate; from about 30 to about 45 weight percent, based on the total weight of the fluid, of tri-n-butyl phosphate; from about 10 to about 15 weight percent, based on the total weight of the fluid, of one or more triaryl phosphates; and an effective amount of a viscosity index improver, an acid control additive and an erosion inhibitor.
