ʻO ka difluoromethane he kinoea kala ʻole a hiki ke hoʻā ʻia me ka ʻala liʻiliʻi e like me ka etera. Hoʻouna ʻia ʻo ia ma ke ʻano he kinoea wai ma lalo o kona kaomi mahu. ʻO ka difluoromethane, i kapa ʻia ʻo difluoromethylene, HFC-32 Methylene Fluoride a i ʻole R-32, he mea hoʻohui kino o ka ʻano like ʻole o ka dihalogenoalkane. Loaʻa iā ia ke ʻano o CH2F2. He kinoea kala ʻole ia i loko o ka lewa a ua hiki ke hoʻoheheʻe ʻia i ka wai, me kahi kūpaʻa wela kiʻekiʻe. frostbite.Hoʻohana mau ʻia ka difluoromethane i nā kaʻina endothermic e like me ka refrigeration a i ʻole ka ea. ma ke ʻano he mea hoʻopau ahi ma muli o kona hiki ke hana i nā kaʻina hana endothermic. ʻO nā hoʻohana ʻē aʻe o ka difluoromethane e pili ana i kona hoʻohana ʻana ma ke ʻano he aerosol propellants, mea puhi puhi, a me nā solvents.

Hoʻohana ʻia ʻo Difluoromethane (CH2F2) i ka etching plasma o nā papa silika.
