<p>Azeotropic compositions of 5-45 weight percent pentafluoroethane and 55-95 weight percent 1,1,1-trifluoroethane boil at -16.9 °C and a pressure of about 51 psia. These compositions are useful as refrigerants, aerosol propellants, heat transfer media, gaseous dielectrics, fire extinguishing agents, expansion agents for polyolefins and polyurethanes and as power cycle working fluids.</p> |
