Polyurethane (PU), lebitso le felletseng la polyurethane, ke mofuta oa motsoako oa macromolecular.E entsoe ke Otto Bayer ka 1937. Polyurethane e arotsoe ka mofuta oa polyester le mofuta oa polyether.Li ka etsoa ka polasetiki ea polyurethane (haholo-holo polasetiki ea foam), fiber ea polyurethane (e bitsoang spandex Chaena), rabara ea polyurethane le elastomer.Polyurethane e bonolo haholo ke sebopeho sa mela ea thermoplastic, se nang le botsitso bo betere, ho hanyetsa lik'hemik'hale, ho tiea le thepa ea mochini ho feta thepa ea foam ea PVC, 'me e na le deformation e fokolang ea compression.Mocheso o motle, ho thibela molumo, ho hanyetsa ts'oaetso le ts'ebetso ea anti-virus.Ka hona, e sebelisoa e le ho paka, ho kenya molumo le lisebelisoa tsa ho sefa.Plastiki e thata ea polyurethane e bobebe ka boima ba 'mele, e sebetsa hantle ka ho kenya molumo le ho kenya mocheso, ho hanyetsa lik'hemik'hale, ho sebetsa hantle ka motlakase, ho bonolo ho sebetsa, le ho monya metsi ka tlase.E sebelisoa haholo indastering ea kaho, likoloi, indastering ea lifofane le lisebelisoa tsa sebopeho sa mogote.Ts'ebetso ea polyurethane elastomer e pakeng tsa polasetiki le rabara, e hanyetsanang le oli, abrasion, mocheso o tlase, botsofali, boima bo phahameng le elasticity.E sebelisoa haholo indastering ea lieta le indastering ea bongaka.Polyurethane e ka boela ea sebelisoa ho etsa li-adhesives, li-coat, letlalo la maiketsetso, joalo-joalo
