They were used as refrigerants,air conditioners, propellants for aerosols, for generating foamed plastics like expanded polystyrene or polyurethane foam, and as solvents for dry cleaning and for general degreasing purposes.
These chemicals were used as refrigerants in air conditioners and refrigerators / freezers. They were used as propellants in cleaners, room deodorizers, furniture polishes, hair spray, perfumes and more. They were used as blowing agents in the production of styrofoam, foam rubber, and more.
CFCs replaced chemicals that were either toxic, highly flammable, highly reactive, or all of the above. It wasn't thought about that their stability would allow them to accumulate in the atmosphere. And it wasn't known that once they survived to reach the upper atmosphere, the payload of the molecule chlorine... (and bromine for the firefighting chemcial halon) would be scissioned off to act as a long lasting photocatalyst for the destruction of ozone.
Nature also throws chlorine into the air, but 82% of the chlorine bearing molecules in the upper atmosphere are Man-sourced.
Ok, for people in Chemistry heres the question that was meant to be answered,
(What are CFC's? How are they used?) Answer ::
- a chemical that consists of chlorine, fluorine and carbon.
-the first self-contained home air-conditioning units and eight million new refrigerators in United States, and plastic foams and propellants in spray cans used CFC's.
Its used in the compressors of refrigerators and air-conditioners.
cleansing agents for electronic components, coolants for air conditioners, foaming agents for the manufacture of insulating materials and so on
Humans use CFC's for various purposes. Some of them are refrigerators, deodorants, spray cans etc. It is mostly used as a coolant.
CFC's are used as coolants. They are used in deodorants, Ac's, spray cans etc.
Today, relatively few, as they have been phased out of their two most common uses due to concern for the environment. Their most common uses were as refrigerants and propellants.
People use CFC's in various day to day life products. These products include deodorants, Ac's etc.
yes
Yes, CFC's are used in sprays. They are used in aerosols too.
In order to protect the ozone layer, we must curb the use of CFCs. IF theses CFcs are not used, the ozone layer will replenish itself.
CFCs are neither soluble in water or reactive with it. Rain has no impact on CFCs
Its used in the compressors of refrigerators and air- conditioners
CFCs were the compressed gas that was used as "spring" to push the can contents out of the container. CFCs have been replaced with HCFCs as a consequence of the Montreal Protocol.
CFC's are used now also. they are used as coolants.

Yes, CFC's are used in sprays. They are used in aerosols too.
CFC's are produced in refrigerants. They are used for cooling.
It was used in refrigirators.

no cfc's are not in use anymore because they damage the enviroment.
Chlorofluorocarbons (CFCs) are non-toxic.
Replacements for CFCs (dependding on use) included:HCFCsNitrogenAirPropane
