IiHydrofluoroolefins (iiHFO) ziikhompawundi ze-organic ezingagcwaliyo eziquka ihydrogen, i-fluorine kunye nekhabhoni. Ngokungafaniyo neehydrofluorocarbons zemveli (iiHFCs) kunye neechlorofluorocarbons (iiCFCs), ezigcweleyo, iiHFOs zii-olefins, ezaziwa ngokuba zii-alkenes. IiHFOs ziphuhliswa njenge "sizukulwana sesine" iifriji ezine-global-warming potential ephantsi kakhulu eyi-0.1% yeeHFCs. Iimveliso zeHFO zinobomi obufutshane emoyeni kwaye zihlelwe njengezingenayo i-ODP (i-Ozone Depletion Potential) kunye ne-GWP ephantsi (i-Global Warming Potential), ezibonelela ngenye indlela enobuhlobo nokusingqongileyo kuneeCFCs, iiHCFCs kunye neeHFCs.
I-polyurethane foam eveliswa kusetyenziswa ii-HFO njenge-air agent evuthelayo isetyenziswa kakhulu kumacandelo eemoto kunye nolwakhiwo ngendlela ye-foams eziguquguqukayo neziqinileyo iqhuba ukukhula kwemarike ye-HFO.
