TDI yog toluene diisocyanate, thiab muaj ob isomers, 2,4-TDI thiab 2,6-TDI.
Cov khoom siv ntau tshaj TDI hauv TDI cov khoom lag luam yog TDI-80 lossis TDI-80/20, feem ntau hu ua T80, uas yog sib xyaw ntawm 2,4-TDI thiab 2,6-TDI nrog qhov sib piv ntawm 80: 20. Ib yam li ntawd, TDI-65 (TDI-65/35, T65) yog qhov sib xyaw ntawm 2,4-TDI thiab 2,6-TDI nrog qhov sib piv ntawm 65: 35, thaum TDI-100 (T100) yog tag nrho ntawm 2,4-TDI.
Cov mis molecular ntawm TDI yog: C9H6N2O2, thiab qhov hnyav molecular yog 174.15, yog li tsis muaj teeb meem dab tsi ntawm cov khoom TDI, cov ntsiab lus NCO yog kho ntawm 48.2%.
Cov ntsiab lus khov ntawm TDI-100 / TDI-80 / TDI-65 txawv nyob ntawm seb muaj pes tsawg tus isomers tam sim no, uas yog: 19.5 ~ 22; 11.5 ~ 14; 3.5 ~ 7.Tam sim no, vim muaj cov isomers, cov dej num ntawm peb kuj txawv heev. Qhov siab dua cov ntsiab lus ntawm 2,4-TDI, qhov siab dua cov khoom lag luam. Yog li ntawd, txawm hais tias TDI-80 yog qhov siv dav tshaj plaws, TDI-100 yog qhov nrov dua hauv cov tshuab nrog lub sijhawm ua haujlwm ntev dua.
TDI -65 feem ntau yog siv rau kev thauj khoom siab thiab siab rebound polyurethane soft foams, polyester polyurethane foams, thiab lwm yam.
TDI-80 feem ntau yog siv rau polyurethane mos foams, polyurethane elastomers, coatings, adhesives, thiab lwm yam.
TDI-100 muaj cov qauv tsis tu ncua thiab feem ntau yog siv rau kev sib txuas ntawm cov prepromers tshwj xeeb, feem ntau yog rau cov cam khwb cia polyurethane elastomers thiab polyurethane coatings.
