Polyudeshane (Pu), ka inoa piha o Pyuretthane, he pupule polymer. 1937 e Ottou Bayer a me nā hana'ē aʻe o kēiaʻatikala. ʻElua mauʻano nui o ka polyurethane, polyester type and polyether type. Hiki iā lākou ke hanaʻia i loko o nā plastichane polyurethane (nui loa), polyurethane fibers
ʻO ka polyxible polyupers ka mea nui i ka hana linear me ka thermoplastictity He mea hoʻoweliweli maikaʻi loa,ʻo ka hanaʻana i ka paleʻana, ka paleʻana i ka paleʻana, a me ka paleʻana o nā mea kanu anti-sticsity. No laila, hoʻohanaʻia ia e like me ke kauʻana, e pale aku ana i nā kumuwaiwai a me nā kānana. ʻO Rigid Polyurethane Firl ka mālamalama, kani leo, nā pale o keʻano o ka paleʻana, nā waiwai kūpono, maʻalahi ka wai. Ua hoʻohana nuiʻia ia ma keʻano he mea hana no ka kūkuluʻana, automomile, kaʻoihana a me ka hoʻoweliweliʻana a me keʻano o ke aniani. ʻO Pyuretonshane Elastomer ma waena o ka plastics a me ka'ōpala,ʻaila, ka paleʻana, kiʻekiʻe loa, kiʻekiʻe loa. Hoʻohana nui ia i kaʻoihana kāmaʻa a me kaʻoihana olakino. Hiki Hiki ke hoʻoikaikaʻiaʻo Polyurehale i loko o nā kikowaena, nā lole, synthetic, syc.

ʻO Polyurethanes kekahi o nā mea waiwai nui loa i ka honua i kēia lā. ʻO kā lākou mau hoʻohana he nui mai ka flaxible flax ma luna o nā meaʻala a me nā meaʻala a me nā mea kanu i hoʻohanaʻia ma luna o nā papa lāʻau a me nā mea hele wāwae a me nā meaʻala a me nā meaʻala i hoʻohanaʻia ma luna o nā papa lāʻau a me nā mea hele wāwae i ka papa Ua hoʻohana nuiʻiaʻo Plyuere He aha nā mea o nā mea e hana ai i nā polyurethannes no laila makemakeʻia? Hāʻawiʻo Polyurethane Durablity i ka lōʻihi o ke olaʻana o nā huahana he nui. ʻO nā hoʻonuiʻia o nā ola ola o ka huahana a me ka mālamaʻana i ka mālamaʻana i nā manaʻo no ka manaʻo maʻamau e like me ka kohoʻana i ke kohoʻana o Plyurethannes [19-21]. ʻO Pyurethanes
