Izigqoko ze-Intumescent ziwuhlobo lwezinto ezingashi ezinwebeka emazingeni okushisa aphezulu ukuze zakhe ungqimba oluvikelayo. Zisetshenziswa kakhulu ekuvikelweni komlilo ezakhiweni, imikhumbi, kanye nemishini yezimboni. Ama-flame retardants, njengezithako zawo eziyinhloko, angathuthukisa kakhulu izakhiwo ezingashi zezingubo zokumboza. Ngaphansi kwezimo zokushisa eziphakeme, ama-flame retardants akhulula amagesi angenayo ngokusebenzisa ukusabela kwamakhemikhali, anciphise ukugcwala komoyampilo, futhi akhuthaze ukunwetshwa kwento enamathelayo ukuze kwakhe ungqimba oluminyene lwekhabhoni, luhlukanise ngempumelelo ukusabalala kokushisa namalangabi.
Ama-flame retardants asetshenziswa kakhulu ahlanganisa i-phosphorus, i-nitrogen, ne-halogen compounds. I-Phosphorus flame retardants ibambezela ukuvutha ngokukhiqiza ungqimba oluvikelayo lwe-phosphate; i-nitrogen flame retardants ikhipha i-nitrogen ukuze ixube amagesi avuthayo; kanye nama-halogen flame retardants aphazamisa ukusabela kweketango lomlilo ngokubamba ama-radicals mahhala. Eminyakeni yamuva nje, izinqamuleli zamalangabi ezilungele imvelo (njengama-halogen-free flame retardants) kancane kancane ziye zaba isizinda socwaningo ngenxa yobuthi bazo obuphansi kanye nobungane bemvelo.
Ngamafuphi, ukusetshenziswa kwama-flame retardants emigqonyeni ye-intumescent akugcini nje ukuthuthukisa izakhiwo zomlilo, kodwa futhi kunikeza ukuvikelwa okuthembekile kokuphepha kwesakhiwo. Ngokuzayo, ngokuthuthukiswa kwezidingo zokuvikela imvelo, amalangabi asebenzayo futhi aluhlaza azoba isiqondiso esibalulekile ekuthuthukisweni kwemboni.
