Ma toluene diisocyanates amagwiritsidwa ntchito makamaka popanga thovu la polyurethane kuti ligwiritsidwe ntchito mu mipando, zogona, ndi mipando yamagalimoto ndi ndege.Zina, zing'onozing'ono zomwe zimagwiritsidwa ntchito ndi polyurethane elastomers (zophimba zophimba galimoto, zodzigudubuza za mafakitale, masewera a masewera ndi nsapato, ndi katundu wamakina) ndi zokutira (zokonzanso magalimoto, zomaliza zamatabwa, ndi zokutira zotsutsana ndi dzimbiri) (ICIS 2009).Toluene diisocyanate-based rigid polyurethane thovu amagwiritsidwa ntchito m'mafiriji apanyumba komanso popangira nyumba zogona kapena zofolera zamalonda mu board kapena laminate form (IARC 1986)."Pour-inplace" kapena "spray-in" thovu lolimba limagwiritsidwa ntchito ngati zotsekera pama trailer amalori, magalimoto onyamula njanji, ndi zotengera zonyamula katundu.Ma alkyds opangidwa ndi polyurethane ali ndi pafupifupi 6% mpaka 7% isocyanate, makamaka toluene diisocyanates, ndipo amagwiritsidwa ntchito ngati zida zokutira, monga zomaliza pansi, zomaliza zamatabwa, ndi utoto.Zovala zochizira chinyezi zimagwiritsidwa ntchito ngati zosindikizira zamatabwa ndi konkriti komanso kumaliza pansi.Zovala za ndege, zamagalimoto, ndi zonyamula anthu nthawi zambiri zimakhala ndi toluene diisocyanate prepolymer system.Ma cell a urethane elastomers amagwiritsidwa ntchito pofunikira mphamvu, kusinthasintha, ndi kuyamwa modzidzimutsa, ndipo amagonjetsedwa ndi mafuta, zosungunulira, ndi cheza cha ultraviolet.Amagwiritsidwa ntchito mu zomatira ndi zosindikizira komanso m'zigawo zamagalimoto, zitsulo za nsapato, mawilo odzigudubuza, zomangira dziwe, ndi matumba amagazi.Amagwiritsidwanso ntchito minda ya inoil ndi migodi.Zinthu zina za elastomer zimapangidwa kuchokera ku isomero yoyera ya 2,4 m'malo mosakaniza 80:20.

Magulu ogwira ntchito mu TDI amachita ndi magulu a hydroxyl kuti apange maulalo a urethane, omwe amagwiritsidwa ntchito popanga thovu losinthika la polyurethane kuti ligwiritsidwe ntchito pamipando, zofunda, ndi mipando yamagalimoto ndi malonda.Ntchito zina ndi monga ma polyurethane elastomers omwe amagwiritsidwa ntchito povala zophimba zamoto, zogudubuza zamafakitale, nsapato zamasewera, komanso katundu wamakina ndi zokutira (zitsulo, matabwa, ndi zokutira zoteteza kuzizira kwambiri).TDI-based rigid polyurethane foam imagwiritsidwa ntchito m'mafiriji apanyumba komanso pomanga nyumba monga kufolera ndi denga lamalonda.TDI spray-in chithovu cholimba chimagwiritsidwa ntchito ngati kutchinjiriza kwa ma trailer amagalimoto, magalimoto onyamula njanji, ndi zotengera zonyamula katundu zakunja.Zovala za TDI zochizira chinyezi zimagwiritsidwa ntchito ngati zosindikizira zamatabwa ndi konkriti komanso kumaliza pansi.
