Toluene diisocyanate e teng ka mefuta e 'meli ea isomere (2,4-toluene diisocyanate le 2,6-toluene diisocyanate), tse nang le thepa le litlamorao tse tšoanang. Toluene diisocyanate e hlahisoa khoebong e le motsoako oa 80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) oa li-isomer tse peli. Mochesong oa kamore, motsoako ke mokelikeli o hlakileng, o mosehla o moputsoa o nang le monko o bohale, o bohale. O lokela ho bolokoa ka sehatsetsing, hole le khanya le mongobo ka setshelong se koetsoeng ka thata sepakapakeng se sa pheleng. Toluene diisocyanate ha e qhibilihe metsing 'me e ka kopanngoa le li-solvents tse ngata tse tloaelehileng tsa organic. Toluene diisocyanate e etsoa ka ho kopanya toluene diamine le carbonyl chloride (phosgene). Toluene diisocyanate e atisa ho sebediswa e le mokedi wa dikhemikhale tlhahisong ya foam ya polyurethane, elastomer, le dikobo, dipente, divarnish, di-enamel tsa terata, di-sealant, dikhomaretsi le di-binder. E boetse e sebediswa e le moemedi wa ho hokahanya tlhahisong ya di-polymer tsa nylon. 2,4-Toluene diisocyanate e sebediswa e le mokedi wa dikhemikhale tlhahisong ya dihlahiswa tsa polyurethane, tse kang difoam, dikobo le di-elastomer.

TDI (toluene diisocyanate) ke thepa ea bohlokoa ea mantlha e tala ea polyurethane. TDI ke motsoako oa mefuta e 'meli ea li-isomer tsa 2,4-TDI le 2,6-TDI, ho kenyeletsoa mefuta e 3 ea mefuta e sebelisoang hangata: TDI-80/20, TDI-100 le TDI-65/35. E sebelisoa haholo-holo tlhahisong ea foam ea polyurethane e tenyetsehang le liphahlo tsa polyurethane elastomer, likhomaretsi, jj.
