| abstract |
A lubricant composition is provided that has reduced deposit formation and a low evaporation allowing for improved performance in high temperature applications relative to conventional high temperature lubricants. The high temperature lubricant composition includes a base oil, wherein the base oil includes at least one polyol ester and at least one pyromellitate ester. In some embodiments, the lubricant composition further includes one or more additives selected from the group of an extreme-pressure additive, an anti-wear additive, an anti-rust additive, a corrosion inhibitor, and an antioxidant, or a combination thereof. Further provided are methods for lubricating an apparatus using the lubricant composition, methods for improving the operational lubrication of a conventional high temperature lubricant, and methods of preparing the high temperature lubricant composition of the present invention. |
