Kule mihla, i-TDI okanye i-MDI ikhethwe ukuba zezona zinto ziphambili zemveliso ye-PU, nokuba i-arhente, ethambile, nelukhuni, i-elaistity, ipeyinti. Hi-owever,nokubaTdiorMdi, yayoIndandatho ye-Bezenekwi-tdi kunye ne-mdiqhagamshela ngokuthe ngqosukwahlukaI-Ekwantiamaqela, kwaye i-pich ye-pi iyothusa nge-NCO ikufuphi ne-NCO. Phantsi kwempembelelo ye-lI-Ight, ubushushu, ioksijini, ngakumbi i-radiation yemitha, yonaInokubangela ukuba i-Ammonia ye-Ammoniakwayevelisa i-amine ye-amine, aphoI-Bezene ye-BezeneRearrangs emvaoxidation. Oku kuya kuvelisa amaqela e-chromophoric ebangela ukuba ityheli kwiimveliso zokugqibela ze-PU.Iliso lomntu linovelwano kakhulu kumbala, i-PPM embalwa yeengcongconi ezinomtsalane iya kukhokelela ekubonakalisweni kweemveliso eziphuzi.
Ukusombulula ingxaki etyheli, eyona ndlela ibalulekileyo kukusebenzisa i-HDI okanye i-IPDI endaweni ye-TDI kunye ne-MDL njengezixhobo eziluhlaza ngaphandle konxibelelwano oluthe ngqo phakathi kwe-Benzene ne-NCO. Kodwa ixabiso lezi zinto ziluhlaza zineentsilelo ezinjalo: Ixabiso libiza kakhulu, ukungavisisani kweekhemikhali, ubungqingqwa akwanelanga .... Oku kuthintela kakhulu ukukhuthaza i-HDI kwi-pu.
Esinye isisombululo kukugcwalisa igesi ye-Insert kwinkqubo yemveliso kunye nokugcina ukwahlula unxibelelwano ngeoksijini kangangoko kunokwenzeka. Eyona ndlela isebenzayo yongeza i-antioxidant kunyeI-UV Ansorber, enokuthi ithintele ngokufanelekileyo kwaye ilibazise ukuvela kwe-phuli.
Yihoo HN130 yi-amine anti-tyhente. Yona'isetyenzisiweNjengomntu wegesi irhasi kwinkqubo yemveliso, inokukhetha kakuhle kwi-nitric oxide (hayi)kwayeI-Nitrogen Dioxide (No2),kwayethintela ngokufanelekileyoukuthoba okubangelwa yiIrhasi ishukumisa.
I-Yihoo HN130 isetyenziswe ngokubanzi kwi-puIzinto ezibunjiweyo, izixhobo zeenyawo, iiplasitiki, i-Polyurethane Fibers kunye ne-Polyurethane Directors, zandisa inkonzo yenkonzo yemvelisos.
