Web1,3,3,3-Tetrafluoropropene (HFO-1234ze (E), R-1234ze) is a hydrofluoroolefin. It was developed as a "fourth generation" refrigerant to replace fluids such as R-134a, as a blowing agent for foam and aerosol applications, and in air horns and gas dusters. [2] The use of R-134a is being phased out because of its high global warming potential (GFA). WebThis colorless gas is being used as a replacement for R-134a as a refrigerant in automobile air conditioners. As of 2024, 90% of new U.S. vehicles from original equipment manufacturers (OEMs) are estimated to use HFO-1234yf. [6] One drawback is it breaks down into persistent organic pollutant short chain perfluorinated carboxylic acids (PFCAs).
