R152a-1,1-Difluoroethane is an organofluorine compound with the chemical formula C2H4F2.
This colorless gas is used as a refrigerant, where it is often listed as R-152a or HFC-152a.
As an alternative to chlorofluorocarbons, it has an ozone depletion potential of zero, a lower global warming potential (120) and a shorter atmospheric lifetime (1.4 years). It has recently been approved for use in automobile applications as an alternative to R-134a.
In addition to serving as a refrigerant, 1,1-difluoroethane is also commonly used in gas duster (commonly thought of as "canned air"), and many consumer aerosol products, especially those subject to stringent VOC requirements.
