OSTI ID:4790127
A grease composition is described which is resistant to heat, carbon dioxide, and radiation. The grease comprises a base mineral oil thickened to a grease consistency with carbon black and containing one or more natural petroleum resins. The carbon black preferably is acetylene black, and the resins may be obtained from resin-containing crudes. The grease composition should have a small sulfur content, preferably less than 0.5%, and a small amount of antioxidant may be added. (D.L.C.)
