Difluoromethane jẹ aini awọ, gaasi ina pẹlu oorun ether diẹ. O ti wa ni gbigbe bi gaasi olomi labẹ titẹ oru tirẹ. Difluoromethane, ti a tun npe ni difluoromethylene, HFC-32 Methylene Fluoride tabi R-32, jẹ ẹya ara-ara ti awọn orisirisi dihalogenoalkane. O ni agbekalẹ ti CH2F2. O jẹ gaasi ti ko ni awọ ni oju-aye ibaramu ati pe o jẹ tiotuka diẹ ninu omi, pẹlu iduroṣinṣin igbona giga.Nitori yo kekere ati aaye farabale, (-136.0 °C ati -51.6 °C lẹsẹsẹ) olubasọrọ pẹlu yellow yii le ja si ni frostbite.Difluoromethane ti wa ni lilo ni awọn ilana endothermic gẹgẹbi itutu tabi air conditioning. bi apanirun ina nitori agbara rẹ lati faragba awọn ilana endothermic.Awọn lilo miiran ti difluoromethane pẹlu lilo rẹ bi awọn apanirun aerosol, awọn aṣoju fifun, ati awọn nkanmimu.
