9. Difluoromethane - Wikipedia

   en.wikipedia.org/wiki/Difluoromethane

   Difluoromethane is thus a relatively low-risk choice among HFC refrigerants, most of which have higher GWP and longer persistence when leaks occur. The common refrigerant R-410A is a zeotropic , 50/50-mass-percent mixture of difluoromethane and pentafluoroethane ( R-125 ).
