Polyurethane (PU), zita rakazara re polyurethane, imhando ye macromolecular compound.Yakagadzirwa naOtto Bayer muna 1937. Polyurethane yakakamurwa kuva polyester mhando uye polyether mhando.Iwo anogona kugadzirwa polyurethane plastiki (kunyanya furo plastiki), polyurethane faibha (inonzi spandex kuChina), polyurethane rabha uye elastomer.Yakapfava polyurethane inonyanya kuve thermoplastic linear chimiro, iyo ine kugadzikana kuri nani, makemikari kuramba, kusimba uye michina zvivakwa kupfuura PVC furo zvinhu, uye ine kushoma kudzvanya deformation.Yakanaka kupisa kupisa, kuvharwa kwenzwi, kushomeka kuramba uye anti-virus kuita.Naizvozvo, inoshandiswa sekurongedza, kuvharidzira ruzha uye kusefa zvinhu.Rigid polyurethane plastiki ine huremu huremu, yakanakisa mukudzivirira inzwi uye kupisa kupisa, makemikari kuramba, yakanaka mukushanda kwemagetsi, nyore kugadzira, uye kuderera mumvura kunyura.Inonyanya kushandiswa mukuvaka, mota, indasitiri yendege uye thermal insulation zvimiro zvemukati.Kuita kwepolyurethane elastomer kuri pakati pepurasitiki nerabha, iyo isingaenderane nemafuta, abrasion, yakaderera tembiricha, kuchembera, kuoma kwakanyanya uye elasticity.Inonyanya kushandiswa muindasitiri yeshangu uye indasitiri yezvokurapa.Polyurethane inogona zvakare kushandiswa kugadzira anonamira, machira, synthetic dehwe, nezvimwe
