ABSTRACT:
The present invention relates to compositions of pentafluoropropane and a fluorinated propane having from 1 to 5 fluorine atoms; a hydrocarbon having from 1 to 5 carbon atoms; 1,1,1,4,4,4-hexafluorobutane, (CF.sub.3).sub.2 CHCH.sub.3, dimethyl ether; or 1,1,1,2,3,4,4,5,5,5-decafluoropentane. 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.
