applications: Segregated Hydrofluoroether (HFE) compounds including Novec 7000, 7100, 7200, 7300, 7500, and 7700 has lower global warming potential (GWP) of ~300. Fluoroketones (FK) compounds including Novec 649 and 774 has very low global warming potential (GWP) of 1. Novec 649 has similar thermo-physical properties to FC-72 making it a good drop-in replacement for low temperature heat transfer.
