A hydrocarbon in which some or all of the hydrogen atoms have been replaced by chlorine and fluorine. Fluorocarbons are used as a feedstock, as a refrigerant, as a solvent and as a blowing agent for plastic foam.
A refrigerant chemical that the federal government has banned, which must be phased out of use by 2000.
A compound consisting of chlorine, fluorine, and carbon. 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 ozone. 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.
a compound consisting of chlorine, flourine and carbon.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.
A family of chemicals composed primarily of carbon, hydrogen, chlorine, and fluorine whose principal applications are as refrigerants and industrial cleansers and whose principal drawback is the tendency to destroy the Earth's protective ozone layer.
A stable chemical containing only chlorine, fluorine and carbon atoms. Chlorofluorocarbons are ozone-depleting substances (ODSs).
Propellant used in some asthma inhalers. A propellant is a gas that helps spray the medicine into your lungs. This type of propellant will eventually be banned in Canada due to its negative effect on the ozone layer. A currently available non-CFC propellant is called "hydrofluoroalkane" or HFA.
Gases made of chlorine, fluorine, and carbon. In the troposphere, a CFC molecule does not normally react with other substances. However, in the stratosphere, ultraviolet radiation breaks apart the CFC molecule releasing a chlorine atom which catalytically destroys many ozone molecules.
(CFC) synthetic chemical that is odorless, nontoxic, nonflammable but reacts with chemicals high in the atmosphere resulting in the depletion of the earth's protective ozone layer. CFCs have been used as propellants in aerosol cans, as refrigerants in refrigerators and air conditioners, and in the manufacture of foam packaging. They are partly responsible for the destruction of the ozone layer.
a fluorocarbon with chlorine; formerly used as a refrigerant and as a propellant in aerosol cans; "the chlorine in CFCs causes depletion of atmospheric ozone"
An organic chemical composed of chlorine, fluorine, and carbon atoms, usually characterized by high stability contributing to a high ODP.
Synthetic chemical that is odourless, non-toxic, non-flammable, and chemically inert. Released into atmosphere, chlorine-containing chemicals rise and are broken down by sunlight, whereupon chlorine reacts with and destroys ozone molecules.
gases used as refrigerants, now banned in Europe and other parts of the world, due to the damage they cause to the ozone layer.
A chemical compound containing chlorine, fluorine, and carbon, used in cooling systems and aerosols. CFCs absorb infrared radiation and consume ozone in the stratosphere.
Compound containing carbon, chlorine, fluorine and sometimes hydrogen. Used as a refrigerant, solvent, or aerosol propellant, or in the manufacture of plastic foams.
(CFC) Chemical compounds containing chlorine, fluorine, and carbon. The term is sometimes used to include chlorocarbons, fluorocarbons, and hydrochlorofluorocarbons.
(CFC) anthropogenic aerosol compound containing chlorine, fluorine, and carbon that is used in propellants, refrigerants, and solvents; freon.
Chemical compounds that are chlorine and fluorine substituted alkane hydrocarbons. CFC's are commonly used as auxiliary blowing agents for foams, refrigerants, aerosol propellants, and cleaning agents.
A chemical compound of one fluorine atom, one carbon atom, and three chlorine atoms. These molecules are very stable and contribute to ozone depletion.
(CFC) - A greenhouse gas which is also an ozone-depleting gas. See also greenhouse gases.
CFCs are chemicals manufactured from hydrocarbons, such as methane, chlorine, fluorine, or bromine and often used as a propellant that traps heat in the atmosphere and contributes to global warming. Commonly used in refrigerants and solvents, they can destroy the ozone in the upper atmosphere when released.
A compound containing chlorine, with high risk of damaging the ozone layer.
