What are CFCs chlorofluorocarbons free radicals used in?

CFCs, or chlorofluorocarbons, are primarily used as refrigerants, propellants in aerosol products, and in foam-blowing applications. However, due to their role in ozone layer depletion, their production and use have been largely phased out under the Montreal Protocol. In the context of free radicals, CFCs can release chlorine atoms when they break down in the atmosphere, which then contribute to the destruction of ozone molecules. As a result, their use has been significantly restricted, and alternatives are being adopted for these applications.
