Polyurethane (PU), izina ryuzuye rya polyurethane, ni polymer polymer.Yakozwe na Otto Bayer mu 1937. Polyurethane igabanijwemo ibyiciro bibiri: ubwoko bwa polyester n'ubwoko bwa polyether.Birashobora gukorwa muri plastiki ya polyurethane (cyane cyane plastiki ifuro ifuro), fibre polyurethane (bita spandex mubushinwa), reberi ya polyurethane na elastomers.
Polyurethane yoroshye cyane ni imiterere yumurongo wa termoplastique, ifite ituze ryiza, irwanya imiti, imbaraga hamwe nubukanishi kuruta ibikoresho bya PVC, kandi bifite ihindagurika rito.Ifite ubushyuhe bwiza, kubika amajwi, kurwanya ihungabana no gukora anti-virusi.Kubwibyo, ikoreshwa nko gupakira, kubika amajwi, gushungura ibikoresho.
Plastike ya polyurethane yoroheje nuburemere, nziza cyane mukuzuza amajwi no kubika ubushyuhe, kurwanya imiti, ibikoresho byiza byamashanyarazi, gutunganya byoroshye, no kwinjiza amazi make.Ikoreshwa cyane mubwubatsi, ibinyabiziga, inganda zindege, ibikoresho byubaka ubushyuhe.Imiterere ya elastomers ya polyurethane iri hagati ya plastiki na reberi, kurwanya amavuta, kurwanya kwambara, 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 80 yiterambere ryikoranabuhanga, ibi bikoresho byakoreshejwe cyane mubijyanye nibikoresho byo munzu, ubwubatsi, ibikenerwa bya buri munsi, ubwikorezi, nibikoresho byo murugo.
Itangazo : Bimwe mubikubiye kuri interineti, kandi inkomoko yagaragaye.Byakoreshejwe gusa kwerekana ukuri cyangwa ibitekerezo bivugwa muriyi ngingo.Zigenewe gusa itumanaho no kwiga, kandi ntabwo ari izindi mpamvu zubucuruzi.Niba hari ihohoterwa, nyamuneka twandikire kugirango dusibe ako kanya.
