ʻO ka Polyurethane Elastomer kahi ʻano mea polymer.ʻO ka Polyurethane kahi ʻano mea hou o ka polymer organik, i kapa ʻia ʻo "ka ʻelima nui o ka plastic", no kāna hana maikaʻi loa i hoʻohana nui ʻia i nā ʻano ʻoihana ʻāina.Hoʻokaʻawale ʻia ia i castable polyurethane elastomer (CPU), thermoplastic polyurethane elastomer (TPU), mixed polyurethane elastomer (MPU).

ʻO ka CPU, cast polyurethane elastomer (CPU) he mea hou polymer synthetic ma waena o ka lāʻau a me ka plastic.I ka hoʻohana pono ʻana, hoʻohana pinepine ʻia e like me ke pani o nā huahana rubber.Ma muli o ka maikaʻi o ka ʻaʻahu ʻana o ka CPU (ʻoi aku ka maikaʻi ma waena o ka elastomer), Cast polyurethane elastomer (CPU no ka pōkole), i kapa ʻia hoʻi ka thermosetting elastomer, lilo i wai ma ka lumi wela a lilo i paʻa ma hope o ka hana ʻana, no laila hoʻohana pinepine ʻia ka CPU no ka hoʻolei ʻana, e like me nā casters , mining, aila hoʻomaʻemaʻe, textile, paʻi paʻi wili, kāna mau huahana i hoʻopau ʻia he kūpaʻa ikaika.

ʻO Type TPU thermoplastic polyurethane elastomer (TPU) he ʻano ia ma waena o ka ʻōpala a me nā plastics he ʻano hou o ka polymer composite material, i ka hoʻomaʻamaʻa ʻana, e like me ka hoʻonui ʻana i ka hana ʻana o nā huahana lāʻau lapaʻau, me ka CPU hoʻokahi he kūpaʻa abrasion maikaʻi loa. elastomer, lumi wela i loko o kahi paʻa, nā ʻano hoʻomehana e hana ai i loko o ka wai a i ʻole ka hopena, ma hope o ka hana ʻana a hoʻopau i ka hoʻolālā, He mea polyurethane paʻa hou.
