811-97-2 / 3159 HFC 134a Gas Refrigerant High Purity , CFC-12
High Purity HFC-134a HFC Refrigerant Gas in 13.6kg Disposable
1,1,1,2-Tetrafluoroethane, R-134a or HFC-134a, is a haloalkane
refrigerant with thermodynamic properties similar to R-12
(dichlorodifluoromethane) but with less ozone depletion potential.
It has the formula CH2FCF3 and a boiling point of −26.3 °C (−15.34
°F) at atmospheric pressure. R-134a cylinders are colored light
HFC-134a,1,1,1,2-Tetrafluoroethane first appeared in the early
1990s as a replacement for dichlorodifluoromethane (R-12), which
has ozone depleting properties. 1,1,1,2-Tetrafluoroethane has been
atmospherically modeled for its impact on depleting ozone and as a
contributor to global warming. Research suggests that over the past
10 years the concentration of 1,1,1,2-tetrafluoroethane has
increased significantly in the Earth's atmosphere, with a recent
study revealing a doubling in atmospheric concentration between
2001 and 2004.

HFC-134a,1,1,1,2-Tetrafluoroethane is an inert gas used primarily
as a "high-temperature" refrigerant for domestic refrigeration and
automobile air conditioners. These devices began using
1,1,1,2-tetrafluoroethane in the early 1990s as a replacement for
the more environmentally harmful R-12 and retrofit kits are
available to convert units that were originally R-12-equipped.
Other uses include plastic foam blowing, as a cleaning solvent, a
propellant for the delivery of pharmaceuticals (e.g.
bronchodilators), wine cork removers, gas dusters and in air driers
for removing the moisture from compressed air.
1,1,1,2-Tetrafluoroethane has also been used to cool computers in
some overclocking attempts. It is also commonly used as a
propellant for airsoft airguns.
