Hydrochlorofluorocarbons

A group of synthetic chemicals used primarily as refrigerants, solvents, and in foam production. They are less harmful to the ozone layer compared to chlorofluorocarbons (CFCs), but still have ozone-depleting potential and contribute to global warming. HCFCs have been phased out or are being gradually replaced under the Montreal Protocol due to their environmental impact, with a focus on transitioning to more environmentally friendly alternatives.
