Chlorofluorocarbon (CFC) composed of carbon, fluorine, and chlorine. When CFCs also contain hydrogen in place of one or more chlorine, they are called hydrochlorofluorocarbons, or HCFCs.
Chlorofluorocarbons (CFCs) are nontoxic, non-flammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, as solvents, and as refrigerants. Due to their chemical properties, CFCs are used as coolants and propellants.
