Toluene diisocyanates o lo'o fa'aaogaina muamua e gaosia ai pulu polyurethane fetuutuunai mo le fa'aoga i meaafale, moega, ma nofoa ta'avale ma vaalele. O isi, fa'aoga laiti e mo polyurethane elastomers (mo ta'avale ta'avale ta'avale, ta'avale falegaosimea, ta'aloga ta'aloga ma seevae, ma mea fa'ainisinia) ma fa'alavalava (mo ta'avale toe fa'auma, fa'auma fafie, ma le maualuga o le fa'aogaina o mea e tete'e ai le pala)(ICIS 2009). Toluene diisocyanate fa'avae polyurethane foam e fa'aoga i totonu o pusaaisa a le fale ma mo fale nofoia po'o fa'atauga fa'atau i luga o laupapa po'o laminate fomu (IARC 1986). E fa'aaogaina le foam “liligi-i totonu” po o le “sua-i totonu” e fa'amama ai mo ta'avale loli, ta'avale uta o nofoaafi, ma pusa uta. Polyurethane-modified alkyds e aofia ai pe tusa ma le 6% i le 7% isocyanate, tele lava toluene diisocyanates, ma e faʻaaogaina e fai ma mea faʻapipiʻi, e pei o le faʻauma o le fola, faʻauma laupapa, ma vali. O pa'u fa'asusu fa'amama e fa'aaogaina e fai ma fa'amaufa'ailoga fafie ma sima ma fa'auma fola. Va'alele, loli, ma pa'u pasese-ta'avale e masani ona fausia i toluene diisocyanate prepolymer system. Castable urethane elastomers o loʻo faʻaaogaina i talosaga e manaʻomia ai le malosi, fetuutuunai, ma le faʻalavelave faʻafuaseʻi, ma e teteʻe i le suauu, solvents, ma le ultraviolet radiation. O lo'o fa'aaogaina i mea fa'apipi'i ma fa'amaufa'ailoga fa'atasi ma vaega ta'avale, fa'avae seevae, uili ta'avale, laina vaituloto, ma taga toto. O lo'o fa'aaogaina fo'i malae ma ena. O nisi oloa elastomer e gaosia mai le mama 2,4 isomer nai lo le 80:20 paluga.

O vaega galue i le TDI e tali atu i vaega o le hydroxyl e fausia ai sootaga o le urethane, lea e faʻaaogaina i le gaosiga o fomu polyurethane fetuutuunai mo le faʻaogaina i meaafale, moega, ma nofoa taʻavale ma fefaʻatauaiga faapisinisi. O isi fa'aoga e aofia ai polyurethane elastomers o lo'o fa'aaogaina i ta'avale ta'avale, ta'avale fale gaosimea, seevae ta'aloga, fa'apea fo'i mea fa'ainisinia ma fa'alavalava (u'amea, fafie, ma fa'alavalava fa'atosina maualuga). TDI fa'avae polyurethane foam e fa'aogaina i totonu o pusaaisa a le aiga ma mo fale faufale e pei o le fa'aofuofu ma le taualuga faapisinisi. TDI spray-i foam malo e faʻaaogaina e fai ma faʻamaʻi mo taavale toso loli, nofoaafi uta taavale, ma pusa uta i fafo. O pa'u TDI e fa'asusu fa'asusu e fa'aaogaina e fai ma fa'amau fa'amau ma fa'auma fola.
