DuPont R134A Freon R-134a as the most widely used in low-temperature environmentally friendly refrigerant, HFC-134a as a result of a good overall performance, making it a very effective and safe alternative to CFC-12, and is mainly used in the use of R12 refrigerant Most field agents, include: refrigerators, freezers, water dispensers, car air conditioners, central air conditioners, dehumidifiers, cold storage, commercial refrigeration, ice machines, ice cream machine, refrigeration condensing units and other refrigeration equipment, but can also be applied to aerosol propellants, medical aerosols, pesticides propellant, polymer (plastic) physical blowing agent, and magnesium alloy to protect gas. R-134a is an internationally recognized CFC-12 best environmental alternatives. HFC-134a does not contain chlorine atoms, can not afford to undermine the role of the ozone layer, has a good safety performance (non-flammable, non-explosive, non-toxic, non-irritating, non-corrosive); its cooling capacity and efficiency and CFC-12 is very close So long regarded as excellent alternative refrigerants. HFC-134a can be widely used as car air conditioners, refrigerators, central air conditioning, commercial refrigeration and other industries refrigerants can be used in medicine, pesticides, cosmetics and cleaning industries.
