I whakaputa te Tari Matū Pākehā (“ECHA”) i tētahi kōnae whānui e pā ana ki te aukati i te 10,000 ngā matū ia- me ngā matū polyfluoroalkyl (“PFAS”). E whakamahia ana te PFAS i roto i te maha o ngā ahumahi, ā, kei roto hoki i te maha o ngā taonga kaihoko. Ko te whāinga o te tono here he aukati i te hanga, te whakanoho ki te mākete me te whakamahi i ngā matū e kino ana ki te hauora tangata me te taiao, me te whakawhāiti i ngā mōrearea e pā ana ki a rātou.
I roto i tā mātou umanga, ka whakamahia te PFAS hei whakamarumaru o waho mō te waea LItz, ko ngā rauemi e tika ana ko te Polytetrafluoroethylene (PTFE), te ethylene-tetrafluoroethylene (ETFE), inā koa ko te ETFE he rauemi tino pai ki te ātete ki te UV, te ozone, te hinu, ngā waikawa, ngā kawakore me te ātete wai.
I te mea ka aukatia e ngā ture Pākehā ngā PFAS katoa, ka noho hei hītori ēnei rauemi i roto i ngā wā tata nei, kua rapua e ngā kaimahi katoa o te Ahumahi he rauemi rerekē pono, he waimarie i kitea e mātou mai i tā mātou kaiwhakarato rauemi ko te TPEE te mea tika.
Ko te TPEE Thermoplastic Polyester Elastomer he rauemi mahi teitei, pāmahana teitei, he maha ngā āhuatanga o te rapa thermoset me te kaha o ngā kirihou hangarau.
He poraka copolymer tēnei kei roto he wāhanga mārō o te polyester me te wāhanga ngohengohe o te polyether. He rite ngā āhuatanga tukatuka o te wāhanga mārō ki te kirihou, engari he ngāwari te wāhanga ngohengohe. He maha ngā āhuatanga pai o tēnei, ā, he mea whakamahi noa i roto i ngā taputapu hiko, hangarau mōhiohio, me ngā ahumahi motuka.
Te akomanga wera o ngā rauemi: -100℃～+180℃，awhe pakeke: 26～75D，
Ko ngā āhuatanga matua o te TPEE ko
He ātete tino pai ki te ngenge
He manawanui pai
Te ātete wera teitei rawa
Pakari, ātete ki te kakahu
He kaha kume pai
Ātete hinu/matū
Te ātete pānga teitei
Ngā āhuatanga miihini pai
Ka whakapau kaha mātou ki te whakauru atu i ētahi atu rauemi hei whakatutuki i ō hiahia. Ā, nau mai hoki ki te tuku mai i ētahi atu rauemi e tika ana.
