Abstract : The invention describes stable grease compositions for use with equipment at extremely low temperatures. The greases consist of about 64.1 to 69.4 weight percent bis(2-ethylhexyl) sebacate, the balance being tetrafluoroethylene polymer having a molecular weight of 10,000-50,000. They have a softening point of 321.1C, a particle size less than 30 microns in diameter, and are supplied as a 7.5 percent suspension in trichlorotrifluoroethane. They are chemically and physically stable over a wide range of conditions.
