Halocarbons

Halocarbons are chemical substances composed of halogen (bromine, chlorine with or without fluorine) and carbon.        

They are used as refrigerants in air-conditioning and refrigeration systems, as extinguishing agents in fire-extinguishing systems, and as blowing agents in foam manufacturing. They are also used as solvents. Halocarbons pose two environmental problems: most contribute to thinning of the ozone layer and are greenhouse gases that contribute to climate change.
