I-Toluene diisocyanate ikhona kwiintlobo ezimbini ze-isomere (2,4-toluene diisocyanate kunye ne-2,6-toluene diisocyanate), ezineempawu kunye nemiphumo efanayo. I-Toluene diisocyanate iveliswa kurhwebo njengomxube we-80:20 (2,4-toluene diisocyanate:2,6-toluene diisocyanate) wee-isomers ezimbini. Kubushushu begumbi, lo mxube lulwelo olucacileyo, olumthubi olukhanyayo olunevumba elibukhali nelinobuhlungu. Kufuneka lugcinwe efrijini, kude nokukhanya kunye nokufuma kwisikhongozeli esivalwe ngokuqinileyo kwindawo engcolileyo. I-Toluene diisocyanate ayinyibiliki emanzini kwaye ixutywa nezinye izinyibilikisi eziqhelekileyo ze-organic. I-Toluene diisocyanate yenziwa ngokuphendula i-toluene diamine kunye ne-carbonyl chloride (phosgene). I-Toluene diisocyanate isetyenziswa kakhulu njengesixhobo esiphakathi sekhemikhali ekuveliseni amagwebu e-polyurethane, ii-elastomers, kunye neengubo, iipeyinti, ii-varnishes, ii-enamel zentambo, ii-sealants, ii-adhesives, kunye nee-binders. Ikwasetyenziswa njenge-arhente yokudibanisa xa kusenziwa ii-polymers ze-nylon. I-2,4-Toluene diisocyanate isetyenziswa njengesixhobo esiphakathi sekhemikhali ekuveliseni iimveliso ze-polyurethane, ezifana nee-foams, iingubo, kunye nee-elastomers.

Isifo sombefu emsebenzini sesona sizathu siphambili sesifo sokuphefumla esinxulumene nomsebenzi kwihlabathi lemizi-mveliso. I-Toluene-2,4-diisocyanate (TDI) yenye yezona zinto zixhaphakileyo zokuphefumla ezikhokelela kwisifo sombefu emsebenzini.

I-TDI (i-toluene diisocyanate) zizinto ezibalulekileyo ezisisiseko ze-polyurethane. I-TDI ngumxube we-2,4-TDI kunye ne-2,6-TDI iintlobo ezimbini ze-isomers, kuquka iintlobo ezi-3 zemigangatho esetyenziswa rhoqo: i-TDI-80/20, i-TDI-100 kunye ne-TDI-65/35. Isetyenziswa kakhulu ekuveliseni i-foam ye-polyurethane eguquguqukayo kunye ne-polyurethane elastomer coating, i-adhesives, njl.njl.

I-Toluene-2,4-diisocyanate yenye yezona isocyanates zisetyenziswa kakhulu. Isetyenziswa ekuveliseni amagwebu aqinileyo naguquguqukayo, ii-elastomers, kunye neengubo. Ukongeza ekusetyenzisweni kwayo njengekhompawundi ecocekileyo, ifumaneka kurhwebo njengomxube we-2,4- kunye ne-2,6-isomers (80: 20% kunye ne-65: 35% ratios, ngokulandelelana).
