Hoʻohana nui ʻia nā Toluene diisocyanates e hana i nā ʻōpū polyurethane maʻalahi no ka hoʻohana ʻana i nā lako, nā moena, a me nā noho kaʻa a me nā mokulele. ʻO nā mea hoʻohana liʻiliʻi ʻē aʻe no nā elastomers polyurethane (no nā uhi pale kaʻa, nā huila ʻoihana, nā kāmaʻa hāmeʻa a me nā kāmaʻa, a me nā waiwai mīkini) a me nā mea hoʻonaninani (no ka hoʻomaʻemaʻe kaʻa, ka hoʻopau lāʻau, a me nā pale anti-corrosion kiʻekiʻe) (ICIS 2009). Hoʻohana ʻia ʻo Toluene diisocyanate-based rigid polyurethane foam i loko o nā pahu hau hale a no ka hale noho a i ʻole ka hale kūʻai ma ka papa a i ʻole ke ʻano laminate (IARC 1986). "Pour-inplace" a i ʻole "spray-in" i hoʻohana ʻia i mea hoʻolalelale no nā kaʻa kaʻa, nā kaʻa ukana a me nā pahu ukana. ʻO ka polyurethane-modified alkyds aia ma kahi o 6% a 7% isocyanate, ka nui o toluene diisocyanates, a hoʻohana ʻia ma ke ʻano he mea uhi, e like me ka pau ʻana o ka papahele, ka pau ʻana o ka lāʻau, a me nā pena. Hoʻohana ʻia nā mea hoʻoheheʻe wai e like me nā lāʻau a me nā mea hoʻopaʻa paʻa a me ka hoʻopau papahele. ʻO nā mokulele, kaʻa kaʻa, a me nā pale kaʻa kaʻa i haku pinepine ʻia me nā ʻōnaehana prepolymer toluene diisocyanate. Hoʻohana ʻia nā urethane elastomers castable i nā noi e koi ana i ka ikaika, ka maʻalahi, a me ka haʻalulu haʻalulu, a kūpaʻa i ka ʻaila, nā solvents, a me ka radiation ultraviolet. Hoʻohana ʻia lākou i nā pūhui adhesive a me ka sealant a me nā ʻāpana kaʻa, nā kāmaʻa kāmaʻa, nā huila rollerskate, nā loko loko, a me nā ʻeke koko. Hoʻohana pū ʻia lākou i nā māla inoil a me nā mines. Hana ʻia kekahi mau huahana elastomer mai ka isomer 2,4 maʻemaʻe ma mua o ka hui 80:20.

Hoʻopili nā pūʻulu hana ma TDI me nā pūʻulu hydroxyl e hana i nā loulou urethane, i hoʻohana ʻia i ka hana ʻana i nā pahu polyurethane maʻalahi no ka hoʻohana ʻana i nā lako, nā moena, a me nā noho kaʻa kaʻa a me nā ʻoihana. ʻO nā mea hoʻohana ʻē aʻe he polyurethane elastomers i hoʻohana ʻia i loko o nā uhi bumper kaʻa, nā huila ʻoihana, nā kāmaʻa haʻuki, a me nā mea hana mīkini a me nā uhi (metala, lāʻau, a me nā pale anticorrosion kiʻekiʻe). Hoʻohana ʻia ʻo TDI-based polyurethane foam i loko o nā pahu hau o ka hale a no ke kūkulu hale e like me ka sheathing a me ka hale kūʻai. Hoʻohana ʻia ʻo TDI spray-in rigid foam ma ke ʻano he insulation no nā kaʻa kaʻa kaʻa, nā kaʻa ukana alahao, a me nā pahu ukana ma waho. Hoʻohana ʻia nā uhi TDI e hoʻomaʻemaʻe i ka wai ma ke ʻano he lāʻau a me nā mea hoʻopaʻa paʻa a me ka hoʻopau papahele.
