    • This invention relates to compositions of cyclopentane, and a compound selected from the group consisting of hydrofluorocarbons, hydrofluoroethers, or fluorinated sulfur compounds. Specifically these compounds may be selected from the group consisting of tetrafluoroethane, hexafluoropropane, pentafluoropropane, tetrafluoropropane, trifluoropropane, difluoropropane, octafluorobutane, hexafluorobutane, pentafluorobutane, nonafluorobutane, difluorobutane, trifluoro-2-methoxyethane and bis(pentafluoroethyl)sulfide. The compositions, which may be azeotropic or azeotrope-like, may be used as refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, aerosol propellants, refrigerants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents or displacement drying agents.
