Chlorofluorocarbons (CFCs) are nontoxic, nonflammable chemicals containing atoms of carbon, chlorine, and fluorine. They are used in the manufacture of aerosol sprays, blowing agents for foams and packing materials, as solvents, and as refrigerants.

Where are CFCs still used?

The study, published Tuesday in Nature Communications, looks at “banked” volumes of three leading chlorofluorocarbon (CFC) chemicals whose production is banned but remain in use today in older refrigeration and cooling systems and in foam insulation.

Why CFC is used in refrigerator?

These compounds are non-flammable, tasteless and odourless, and chemically stable. Their other important property is their volatility, having boiling points close to zero degrees Centigrade. These physical properties make them ideal for use as refrigerant gases in air conditioners, freezers and refrigerators.
