Mixtures of 1,1,1-trifluoroethane perfluoropropane and propane and their use as refrigerant fluids as aerosol propellants or as blowing agents for plastic foams

摘要

To replace chlorofluorocarbons as refrigerant fluids, the invention proposes to employ mixtures containing, on a mass basis, approximately 25 to 65 % of 1,1,1-trifluoroethane, 1 to 70% of perfluoropropane, and 5 to 34 % of propane. The mixtures according to the invention can also be employed as aerosol propellants or as blowing agents for plastic foams.
