Hydrochlorofluorocarbons (HCFCs)

Hydrochlorofluorocarbons (HCFCs) are chemical compounds containing hydrogen, chlorine, fluorine, and carbon, used primarily as refrigerants, solvents, and foam-blowing agents. They were developed as alternatives to chlorofluorocarbons (CFCs), which damage the ozone layer. HCFCs have a lower ozone depletion potential but still contribute to ozone layer thinning and global warming. Their use is being phased out globally under international agreements like the Montreal Protocol, in favor of more environmentally friendly substances. HCFCs are managed carefully due to their environmental impact, though they are considered a transitional solution in the shift toward sustainable alternatives.
