FHC-2000, a hydrofluoroether, is a third generation blowing agent for the polyurethane industry and may be a component of thermal insulation products used for residential and industrial buildings as well as for storage applications. The thermal conductivity and GWP (Global Warming Potential) properties of FHC-2000 are outstanding and compare favorably to other blowing agents. FHC-2000 is also a base material for a wide range of blends useful as polyurethane foaming agents, industrial solvents and heat transfer fluids. Foams produced with FHC-2000 have fine cellular structures with good insulating properties and good compressive strength. Additional potential uses for FHC-2000 are as a cleaning agent, as a drying agent, in dust removal, as a carrier solvent, as a diluent for fluorinated greases and as a cooling agent.
