Polyurethane (PU), magaca buuxa waa poliurethane, waa iskudar polymer ah.Waxaa sameeyay Otto Bayer 1937. Polyurethane wuxuu u qaybsan yahay laba qaybood: nooca polyester-ka iyo nooca polyeter-ka.Waxa laga samayn karaa balaastikada poliurethane (badanaa balaastig xumbo leh), fiilooyinka poliurethane (oo loo yaqaan spandex ee Shiinaha), caag polyurethane iyo elastomers.
Polyurethane jilicsan inta badan waa qaab-dhismeed toosan oo heerkulbeeg ah, kaas oo leh xasillooni ka wanaagsan, caabbinta kiimikaad, adkeysi iyo sifooyin farsamaysan marka loo eego walxaha xumbo ee PVC, oo leh cillad yar oo ciriiri ah.Waxay leedahay dahaarka kulaylka wanaagsan, dahaarka dhawaaqa, iska caabin shoogga iyo waxqabadka anti-virus.Sidaa darteed, waxaa loo isticmaalaa sida baakadaha, dahaarka dhawaaqa, walxaha shaandhada.
Caag adag oo polyurethane ah ayaa miisaankeedu fudud yahay, aad ugu fiican dahaarka dhawaaqa iyo kuleylka kuleylka, caabbinta kiimikada, sifooyinka korantada ee wanaagsan, habaynta sahlan, iyo nuugista biyaha hooseeya.Waxaa inta badan loo isticmaalaa dhismaha, baabuurta, warshadaha duulista, qalabka dahaaridda kulaylka.
Waxqabadka elastomer polyurethane wuxuu u dhexeeyaa caag iyo caag, caabbinta saliidda, caabbinta xirashada, iska caabinta heerkulka hooseeya, caabbinta gabowga, adkaanta sare iyo barti.Inta badan loo isticmaalo warshadaha kabaha iyo warshadaha caafimaadka.Polyurethane waxa kale oo loo isticmaali karaa in lagu sameeyo xabag, dahaar, maqaar synthetic, iwm.
Polyurethane wuxuu soo muuqday 1930-yadii.Ka dib ku dhawaad 80 sano oo horumarinta tignoolajiyada, maaddadan ayaa si weyn loogu isticmaalay goobta alaabta guriga, dhismaha, baahiyaha maalinlaha ah, gaadiidka, iyo qalabka guriga.
