摘要:
This invention provides azeotrope-like compositions of 1, 1, 1, 2-tetrafluoroethane, 1,1,1,3,3-pentafluoropropane-245fa and water that are environmentally desirable for use as refrigerants, aerosol propellants, metered dose inhalers, blowing agents for polymer foam, heat transfer media, and gaseous dielectrics.
