Abstract (en)
[origin: WO9508603A1] Compositions include mixtures of trifluoromethane and pentafluoropropane; fluoromethane and pentafluoropropane; tetrafluoroethane and heptafluoropropane or pentafluoropropane; 1,1-difluoroethane and heptafluoropropane, or pentafluoropropane; heptafluoropropane and pentafluoropropane, tetrafluoropropane, trifluoropropane, difluoropropane, or fluoropropane; or 1,1,1,2,2,3,3-heptafluoropropane and 1,1,1,2,3,3,3-heptafluoropropane. These compositions are useful as refrigerants, cleaning agents, expansion agents for polyolefins and polyurethanes, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, power cycle working fluids, polymerization media, particulate removal fluids, carrier fluids, buffing abrasive agents, and displacement drying agents.
