HFO1234ze

HFO1234ze, also known as trans-1-hydroxy-1,1,1,2,3,3,3-heptafluoropropane, is a hydrofluoroolefin refrigerant. It has the chemical formula C3H2F6O. HFO1234ze is a colorless gas with a faint odor. It is primarily used as a propellant in aerosol products, a blowing agent for foam insulation, and a refrigerant in air conditioning systems. Its low global warming potential (GWP) and zero ozone depletion potential (ODP) make it an environmentally friendly alternative to older refrigerants.

The development of HFO1234ze was driven by environmental regulations aimed at phasing out substances that contribute to ozone depletion and climate change. It belongs to a class of compounds called hydrofluoroolefins, which are designed to break down quickly in the atmosphere, thus minimizing their environmental impact. HFO1234ze has a GWP of less than 1, significantly lower than many legacy refrigerants.

In aerosol applications, HFO1234ze replaced hydrofluorocarbons (HFCs) like HFC134a, which have higher GWPs. Its flammability is a consideration, and it is classified as mildly flammable (A2L). Manufacturers have implemented safety measures and adapted product formulations to accommodate this property. Similarly, in foam blowing, it offers improved insulation performance while reducing greenhouse gas emissions.

HFO1234ze has undergone extensive testing and evaluation by regulatory bodies and industry associations to ensure its safety and efficacy. Its adoption is part of a broader global transition towards more sustainable chemical technologies.
