New page

Chlorofluorocarbon (CFC) is a compound consisting of [[chlorine]], [[fluorine]], and [[carbon]].

CFCs are very stable in the [[troposphere]]. They move to the Stratosphere and are broken down by strong ultraviolet light, where they release chlorine atoms that then deplete the [[ozone]] layer.

CFCs are commonly used as refrigerants, solvents, and foam blowing agents. The most common CFCs are CFC-11, CFC-12, CFC-113, CFC-114, and CFC-115.

The [[ozone depletion potential]] (ODP) for each CFC is, respectively, 1, 1, 0.8, 1, and 0.6.
