Hei kirihou hangarau wera me ngā āhuatanga whānui kaha i ngā tau tata nei, e whakamahia whānuitia ana te papa POM i roto i te umanga hanga me te umanga hanga. E whakaaro ana ētahi ka taea e te papa POM te whakakapi i ngā rauemi whakarewa pēnei i te maitai, te konutea, te parahi me te konumohe. Nā te mea he kirihou hangarau thermoplastic te papa POM me te ira rewa teitei me te tioata teitei, me whakarerekē me te whakapai ake ina whakamahia i roto i ngā horopaki tono rerekē.
Ko ngā āhuatanga o te rauemi POM he pakeke teitei, he ātete ki te kakahu, he ātete ki te makuku, he ātete ki ngā matū, me ētahi atu. He kaha tōna ātete ki te wahie, he ātete ki te ngenge, he kaha te pānga, he pakari teitei, he ātete ki te ngoki, he pai te pumau o ngā āhuatanga, he whakahinuhinu-ā-ia anō. He nui te herekoretanga hoahoa, ā, ka taea te whakamahi mō te wā roa i te -40 ki te 100 °C. Heoi, nā te nui o te mātotoru whanaunga, he iti te kaha pānga kua tapahia, he ngoikore te ātete ki te wera, kāore e pai mō te aukati mura, kāore e pai mō te tā, ā, he nui te tere whakaheke hanga, nō reira he kōwhiringa kore e taea te karo i te whakarerekētanga POM. He tino ngāwari te whakatio i te POM i te wā o te tukanga hanga, ā, ka puta he porowhita nui ake. Ina pāngia te rauemi, ka ngāwari ēnei porowhita nui ki te hanga i ngā pūwāhi kukū ahotea, ka kino hoki te rauemi.
He tino aro nui te POM ki ngā koki, he iti te kaha o te pānga ki ngā koki, ā, he tere whakaheke te hanga. He ngāwari te hua ki te ahotea o roto, ā, he uaua ki te hanga kia piri. Ka whakawhāitihia e tēnei te whānuitanga o te whakamahinga o te POM, ā, kāore e taea te whakatutuki i ngā whakaritenga ahumahi i ētahi āhuatanga. Nō reira, kia pai ake ai te urutau ki ngā taiao mahi uaua pēnei i te tere tere, te pēhanga teitei, te pāmahana teitei, me te kawenga teitei, me te whakawhānui ake i te whānuitanga o te whakamahinga o te POM, me whakapai ake te pakari o te pānga, te ātete wera me te ātete waku o te POM.
Ko te mea nui ki te whakarerekētanga o te POM ko te hototahitanga i waenga i ngā wāhanga o te pūnaha hiato, ā, me whakanui ake te whanaketanga me te rangahau i ngā hototahi maha-mahi. Mā te pūnaha tiēre hou kua whakawhanakehia me te whakapakari i te ionomer polymerized in-situ ka hangaia e te pūnaha hiato he whatunga honohono pumau, he huarahi rangahau hou hei whakaoti i te hototahitanga interphase. Ko te mea nui ki te whakarerekētanga matū kei roto i te whakaurunga o ngā rōpū maha-mahi ki roto i te mekameka ngota mā te tīpako i ngā comonomer i te wā o te tukanga hanga hei whakarato i ngā āhuatanga mō te whakarerekētanga atu; te whakatikatika i te maha o ngā comonomer, te arotau i te hoahoa o te hanganga ngota, me te hanga raupapatanga me te mahi me te POM mahi-teitei.
