Hydrofluoroether
A Hydrofluoroether (HFE) is a complex organic solvent. As a non-ozone-depleting chemical, it was developed originally as a replacement for CFCs, HFCs, HCFCs, and PFCs HFE does not occur naturally. It is colorless, odorless, tasteless, low toxicity, low viscosity, and liquid at room temperature. It is visually indistinguishable from water at room temperature. The vapor-point of HFE varies by chemistry from 50C to nearly 100C.
