Ama-hydrofluoroolefins (ama-HFO) ayizinto eziphilayo ezingagcwalisiwe eziqukethe i-hydrogen, i-fluorine kanye ne-carbon. Ngokungafani nama-hydrofluorocarbons endabuko (ama-HFC) kanye nama-chlorofluorocarbons (ama-CFC), agcwele, ama-HFO angama-olefin, aziwa nangokuthi ama-alkenes. Ama-HFO athuthukiswa njengeziqandisi "zesizukulwane sesine" ezinamandla aphansi kakhulu okufudumala komhlaba okuyi-0.1% yama-HFC. Imikhiqizo ye-HFO inesikhathi esifushane sokuphila emoyeni futhi ihlukaniswe njengengenayo i-ODP (i-Ozone Depletion Potential) kanye ne-GWP (i-Global Warming Potential) ephansi, enikeza enye indlela enobungani nemvelo kune-CFCs, ama-HCFC kanye nama-HFCs.
I-foam ye-polyurethane ekhiqizwa kusetshenziswa ama-HFO njenge-ejenti yokufutha isetshenziswa kabanzi emikhakheni yezimoto nezokwakha ngendlela yama-foam aguquguqukayo futhi aqinile iqhuba ukukhula kwemakethe ye-HFO.
