Difluoromethane R-32, aswell alleged HFC-32 or R-32, is an amoebic admixture of the dihalogenoalkane variety. Difluoromethane R-32 is based on methane, except that two of the four hydrogen atoms accept been replaced by fluorine atoms. Hence the blueprint is CH2F2 instead of CH4 for accustomed methane.
Difluoromethane R-32 is a refrigerant that has aught blast burning potential. Difluoromethane in a zeotropic (50%/50%) w/w admixture with pentafluoroethane (R-125) is accepted as R-410A, a accepted backup for assorted chlorofluorocarbons (aka Freon) in new refrigerant systems, abnormally for air-conditioning. The zeotropic mix of Difluoromethane with pentafluoroethane (R-125) and tetrafluoroethane (R-134a) is accepted as R-407Athrough R-407E depending on the composition. Likewise the azeotropic (48.2%/51.8% w/w) admixture with chlorotrifluoromethane (R13). As a refrigerant difluoromethane is classified as A2L- hardly combustible . Although it has aught blast burning potential, it has all-around abating abeyant 675 times that of carbon dioxide, based on a 100-year time anatomy .
