Ko te TPU he whakarāpopototanga mō tōna ingoa Pākehā (Thermoplastic polyurethanes), ā, ko tōna ingoa Hainamana ko te Thermoplastic polyurethane elastomer rubber. He momo matū pūhui polymer tēnei, ko te āhuatanga o te rauemi TPU he ātete ki te kakahu, he pai te ngāwari, he kaha miihini teitei, he pai te mahi tukatuka, he ātete pāmahana teitei, he pai te ātete wai. Ko te rauemi Polyurethane, e mōhiotia ana ko te polyurethane, he momo hou anō hoki o te rauemi pūhui polymer, he mea whakamahi noa i roto i te umanga tukatuka, e mōhiotia ana hoki ko te "kirihou tuarima", ko te whakarāpopototanga o te ingoa Pākehā ko PUR. I tēnei wā, he whānui te whakamahinga o te rauemi, inā koa ko ngā kaihanga taura. He maha ngā taura TPU e hangaia ana e Wenchang, ka whakaurua e mātou te tono o te taura polyurethane TPU i roto i te umanga.
Tuatahi, te pāmahana teitei
He ātete-mau te TPU, he ātete pāmahana teitei, he ātete waikura hoki: he ngāwari te waikura o ngā rauemi mata kirihou whānui i te taiao neke atu i te 70℃ mō te wā roa, he pai te ātete waikura o te TPU; i te nuinga o te wā, ka taea e te ātete pāmahana TPU te eke ki te 120℃. He ātete kakahu nui te PUR: neke atu i te 20 miriona ngā wā o te taura ngāwari teitei, neke atu i te 50 miriona ngā wā o te taura ngāwari teitei ka whakamahia te PUR, nā te mea he pai ake te ātete piko, te ātete kakahu.
Tuarua, te ātete ki te pāmahana iti
Ko te ātete pāmahana iti o te TPU me te PUR te whiringa tuatahi o ngā rauemi rongonui i te ao rererangi. He whānui te whakamahinga i roto i te ao rererangi, nā te mea he tino ātete ki te makariri te taura karetao TPU me te PUR, ā, he pai ake te pumau o te tuku i te pāmahana iti i ētahi atu rauemi.
Tuatoru, he ātete ki te hinu me te ngāwari ki te hiri i te wera
Ko ngā TPU me ngā PUR, kāore he kakara, kāore he paitini, he ātete hinu ki te wera, kāore he kakara, he rauemi kāore he paitini. He rongonui tēnei TPU me ngā PUR i te mākete, nā te mea he ātete hinu te rauemi, he ātete kakahu, he ātete pāmahana teitei, he ātete pāmahana iti pai, he ngāwari pai, ā, kāore he paitini, kāore hoki he kakara rerekē i roto i te hanga ahumahi me ngā kaupapa hanga he tino whānui, nō reira ko te nuinga o te wā ka whiriwhiria te umanga taura hei umanga hanga mīhini, he whānui te whakamahinga i roto i ngā ringa karetao me ētahi atu hononga nekeneke, he pai te mahi a tēnei taura.
