Polyurethane (PU), izina ryuzuye rya polyurethane, ni ubwoko bwa macromolecular.Yakozwe na Otto Bayer mu 1937. Polyurethane igabanijwemo ubwoko bwa polyester n'ubwoko bwa polyether.Zishobora gukorwa muri plastiki ya polyurethane (cyane cyane plastiki ifuro), fibre polyurethane (bita spandex mubushinwa), reberi ya polyurethane na elastomer.Polyurethane yoroshye cyane ni imiterere yumurongo wa termoplastique, ifite ituze ryiza, irwanya imiti, imbaraga hamwe nubukanishi kuruta ibikoresho bya PVC, kandi bifite ihindagurika rito.Gukwirakwiza ubushyuhe bwiza, kubika amajwi, kurwanya ihungabana no gukora anti-virusi.Kubwibyo, ikoreshwa nko gupakira, kubika amajwi no kuyungurura ibikoresho.Plastike ya polyurethane yoroheje nuburemere, nziza cyane mukuzuza amajwi no kubika ubushyuhe, kurwanya imiti, gukora neza mumashanyarazi, kuyitunganya byoroshye, no gufata amazi make.Ikoreshwa cyane mubwubatsi, ibinyabiziga, inganda zindege nibikoresho byubaka ubushyuhe.Imikorere ya polyurethane elastomer iri hagati ya plastiki na reberi, irwanya amavuta, abrasion, ubushyuhe buke, gusaza, ubukana bwinshi na elastique.Ikoreshwa cyane cyane mu nganda zinkweto ninganda zubuvuzi.Polyurethane irashobora kandi gukoreshwa mugukora ibifatika, gutwikira, uruhu rwubukorikori, nibindi
