Fluorocarbons

Carbon-fluorine compounds that often contain other elements such as hydrogen, chlorine, or bromine. Fluorocarbons are used as refrigerants and propellants in aerosol products, among other uses. Common fluorocarbons include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs). In 1978 the United States began phasing out the use of CFCs because of their ozone-depleting effect.
