Hydrofluoroether is a general term for an ether compound containing a hetero atom such as an oxygen atom in the molecule. It has a promising compound with zero ozone digestion value (ODP), low global greenhouse potential (GWP), and atmospheric retention. The short time is considered a new type of ideal chlorofluorocarbon (CFC) alternative. In addition to excellent environmental properties, hydrofluoroethers are also characterized by low toxicity, non-corrosive, non-combustible, no fumes, easy to store and transport, and have unparalleled advantages over other alternatives.
