Hydrochlorofluorocarbons
Hydrochlorofluorocarbons (HCFCs) are a group of chemical compounds used primarily as refrigerants, solvents, and foam-blowing agents. They contain hydrogen, chlorine, fluorine, and carbon, which makes them less harmful to the ozone layer compared to their predecessors, chlorofluorocarbons (CFCs). However, HCFCs still contribute to ozone depletion and have a global warming potential.
Due to their environmental impact, the production and consumption of HCFCs are being phased out under the Montreal Protocol, an international treaty aimed at protecting the ozone layer. Many countries are transitioning to more environmentally friendly alternatives, such as hydrofluorocarbons (HFCs) and natural refrigerants.
