partially halogenated chlorofluorohydrocarbon
Hydrocarbons whose hydrogen atoms have been partially substituted with chlorine and fluorine. They are used in refrigeration, air conditioning, packaging, insulation, or as solvents and aerosol propellants. Because they are not destroyed in the lower atmosphere they drift into the upper atmosphere where their chlorine components destroy ozone. (Source: LANDY)
