The Air Force Looks at SYNTHETIC LUBRICANTS 500180
SYNTHETIC lubricants-materials that are wholly or largely nonpetroleum - are being looked at with favor by the Air Force, the authors indicate, because of limitations in the performance of petroleum lubricants at extremely high and extremely low temperatures.
The types of materials investigated as synthetic lubricants included: dibasic acid ester, polyalkylene glycols, organic silicon compounds, halogenated hydrocarbon, and inorganic radical-organic base ester.
