Hydrofluoroethers are compounds composed of hydrogen, fluorine, oxygen, and carbon atoms, featuring an ether structure. They have an ozone depletion potential (ODP) of zero, a low global warming potential (GWP), and a very short atmospheric lifetime, making them considered ideal substitutes for CFCs.
Hydrofluoroethers 7100 and 7200 are listed as acceptable substitutes for CFCs on the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy (SNAP) list, designated as "Acceptable" (unrestricted use). Additionally, they have been excluded by the EPA from the volatile organic compounds (VOC) category. These substances can be used in industries such as precision instruments, electronics, semiconductors, high-end medical equipment, and aerospace manufacturing.
In addition to excellent environmental properties, hydrofluoroethers also have outstanding thermal and chemical stability, moderate solubility, low toxicity, non-corrosiveness, non-flammability, and do not produce smoke or dust. They are highly compatible with various materials, easy to store and transport, and are widely used in numerous fields, including medical, electronics, metal processing, precision instruments, optical lenses, communications, and aerospace industries.
