Polyurethane (PU), izina ryayo ryuzuye ni polyurethane, ni polymer.Yakozwe na Otto Bayer nabandi mu 1937. Polyurethane ifite ibyiciro bibiri: ubwoko bwa polyester nubwoko bwa polyether.Birashobora gukorwa muri plastiki ya polyurethane (cyane cyane ifuro), fibre polyurethane (bita spandex mubushinwa), reberi ya polyurethane na elastomers.
Polyurethane yoroshye ifite ahanini umurongo wa termoplastique.Ifite ituze ryiza, irwanya imiti, irwanya imbaraga hamwe nubukanishi kuruta ibikoresho bya PVC ifuro, kandi ifite ihindagurika rito.Gukwirakwiza ubushyuhe bwiza, kubika amajwi, kurwanya vibrasiya no gukora virusi.Kubwibyo, ikoreshwa nko gupakira, kubika amajwi, no kuyungurura ibikoresho.
Plastike ya polyurethane ifite uburemere bworoshye, iringaniza amajwi meza, imikorere yubushyuhe, imiti irwanya imiti, imikorere myiza yamashanyarazi, kuyitunganya byoroshye, hamwe no gufata amazi make.Ikoreshwa cyane nkibikoresho byubaka mubwubatsi, ibinyabiziga, inganda zindege, hamwe nubushyuhe bwumuriro.
Imiterere ya polyurethane elastomer iri hagati ya plastiki na reberi, kurwanya amavuta, kurwanya abrasion, kurwanya ubushyuhe buke, kurwanya gusaza, gukomera cyane na elastique.Ahanini ikoreshwa mubikorwa byinkweto ninganda zubuvuzi.Polyurethane irashobora kandi gukoreshwa mugukora ibifatika, gutwikira, uruhu rwubukorikori, nibindi.
Polyurethane yagaragaye muri 1930.Nyuma yimyaka hafi mirongo inani yiterambere ryikoranabuhanga, ibi bikoresho byakoreshejwe cyane mubijyanye nibikoresho byo munzu, ubwubatsi, ibikenerwa bya buri munsi, ubwikorezi, nibikoresho byo murugo.
Isoko rya polyurethane kwisi yose riherereye mubihugu byateye imbere muburayi na Amerika.Agace ka Aziya-Pasifika gahagarariwe ahanini n'Ubushinwa, Ubuyapani, na Koreya y'Epfo.Ibihugu n'uturere twavuze haruguru bingana na 90% by'isoko rya polyurethane ku isi.Muri byo, igihugu cyanjye gikoresha polyurethane yose hamwe ni kimwe cya kabiri cyisi.Hariho ubwoko bwinshi bwibicuruzwa bya polyurethane kwisi kandi bikoreshwa mubice bitandukanye.Mu mpera z'umwaka wa 2016, umusaruro wa polyurethane ku isi umaze kugera kuri toni miliyoni 22.
