Synthetic
Clean
OriginProduced from hydrofluorocarbons, a synthetic chemical family derived from petroleum feedstocks and fluorine compounds. Synthesized through controlled fluorination and hydrogenation of chlorofluorocarbon precursors as a replacement for ozone-depleting substances.
1,1-Difluoroethane is colorless, odorless gas shipped as a liquefied gas under its vapor pressure. Contact with the liquid can cause frostbite. It is easily ignited. Its vapors are heavier than air and a flame can travel back to the source of leak very easily. This leak can be either a liquid or vapor leak. It can asphyxiate by the displacement of air. Under prolonged exposure to fire or heat the containers may rupture violently and rocket.
