Definitions for "CFCs"
synthetic products, which do not occur naturally and contain chlorine and fluorine; commonly used in various industrial processes and as refrigerants and, prior to 1990, as a propellant gas for sprays; deplete ozone in the stratosphere and are powerful greenhouse gases
Chlorofluorocarbons or chlorinated fluorocarbons are artificially produced chemicals that are partly responsible for depletion of the ozone layer. CFCs have been used in refrigerants and a variety of other solvents since introduced in mid-1930.
One of the families of ozone depleting substances (ODS). Chemicals comprised of chlorine, fluorine and carbon. Their atmospheric lifetimes range from 55 to 1,700 years. Scientists have invented dozens of kinds of CFCs, but three dominate commerce: CFC-12, used in foams, aerosols, refrigeration, sterilization, and air conditioning; CFC-11, used in foams, aerosols and industrial refrigeration; and, CFC-113, used in solvents. The Montreal Protocol bans the consumption of newly-made CFCs outside Article 5 countries beginning January 1, 1996. Non-Article 5 countries, however, may produce 15% of their 1986 CFC production levels after this date, for essential domestic use and for export to Article 5 countries.
