E lua ituaiga isomeric o le Toluene diisocyanate (2,4-toluene diisocyanate ma le 2,6-toluene diisocyanate), e tutusa o latou uiga ma aafiaga. O le Toluene diisocyanate e gaosia faapisinisi o se paluga 80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) o isomers e lua. I le vevela o le potu, o le paluga o se vai manino, samasama vaivai ma se manogi malosi ma malosi. E tatau ona teuina i lalo o le pusaaisa, mamao ese mai le malamalama ma le susu i totonu o se pusa tapuni mau i se ea e le gaoioi. O le Toluene diisocyanate e le solo i le vai ma e mafai ona fefiloi ma le tele o solvents masani. O le Toluene diisocyanate e faia e ala i le fa'afefiloi o le toluene diamine ma le carbonyl chloride (phosgene). E masani ona fa'aaogaina le Toluene diisocyanate o se vaila'au fa'afefiloi i le gaosiga o polyurethane foams, elastomers, ma coatings, vali, varnishes, wire enamels, sealant, adhesives, ma binders. E fa'aaogaina fo'i o se mea e fa'afeso'ota'i ai i le gaosiga o nailon polymers. O le 2,4-Toluene diisocyanate e fa'aaogaina o se vaila'au fa'afefiloi i le gaosiga o oloa polyurethane, e pei o foams, coatings, ma elastomers.

I le gaosiga o foams polyurethane ma isi elastomers.

O le tale i galuega o le mafuaʻaga autū lea o faʻamaʻi manava e fesoʻotaʻi ma galuega i le lalolagi o pisinisi. O le Toluene-2,4-diisocyanate (TDI) o se tasi o mea e sili ona taatele e faʻaosofia ai le tale i galuega e mafua ai le tale i galuega.

O le TDI (toluene diisocyanate) o se mea taua e fai ai le polyurethane. O le TDI o se fa'afefiloi o le 2,4-TDI ma le 2,6-TDI ituaiga isomers e lua, e aofia ai ituaiga e 3 o vasega e masani ona fa'aaogaina: TDI-80/20, TDI-100 ma le TDI-65/35. E fa'aaogaina tele i le gaosiga o le polyurethane foam ma le polyurethane elastomer coatings, kelu, ma isi mea fa'apena.

O le Toluene-2,4-diisocyanate o se tasi o isocyanates e sili ona faʻaaogaina lautele. E faʻaaogaina i le gaosiga o urethane foams malō ma fetuutuunai, elastomers, ma ufiufi. I le faʻaopoopoga i lona faʻaaogaina o se tuʻufaʻatasiga mama, e maua faʻapisinisi o se faʻafefiloi o le 2,4- ma le 2,6-isomers (80: 20% ma le 65: 35% fua faʻatatau, i le faʻasologa).
