Hydrofluoroether

Hydrofluoroethers (HFEs) are a class of organic solvents. As non-ozone-depleting chemicals, they were developed originally as a replacement for CFCs, HFCs, HCFCs, and PFCs. They are typically colorless, odorless, tasteless, low toxicity, low viscosity, and liquid at room temperature. The boiling point of HFEs vary from 50 °C (122 °F) to nearly 100 °C (212 °F). Although 3M first developed HFEs, other manufacturers have begun producing them.
