(A) "Freon" is a trade name for CFC and HCFC refrigerants sold by DuPont. Other trade
names include AlliedSignal's "Genetron" and ICI's "Arcton". Various companies sell
the same CFCs, HCFCs, HFCs, and other products under different names.

(Q) What refrigerants are used now?

(A) The most common ozone-depleting refrigerants are CFC-12, R-502, and HCFC-22. R-502 is a blend of 48.8% HCFC-22 and 51.2% CFC-115.

(Q) What does CFC stand for

(A) Chlorofluorocarbon (CFC): a compound consisting of chlorine, fluorine, and
carbon.

(Q) How do CFC's effect the ozone

(A) CFCs are very stable in the troposphere. They are broken down by strong ultraviolet
light in the stratosphere and release chlorine atoms that then deplete the ozone layer.
CFCs are commonly used as refrigerants, solvents, and foam blowing agents.

(Q) What CFC's are used the most?

(A) The most common CFCs are CFC-11, CFC-12, CFC-113, CFC-114, and CFC-115.
