He maha ngā āhuatanga pai o te PVC, ā, e whakamahia whānuitia ana, engari kāore i te tino tika tōna kaha pānga, tōna kaha pānga pāmahana iti, me ētahi atu āhuatanga pānga. Nō reira, me tāpiri ngā whakarerekētanga pānga hei whakarerekē i tēnei ngoikoretanga. Ko ngā whakarerekētanga pānga noa ko te CPE, ABS, MBS, EVA, SBS, me ētahi atu. Ka whakanui ake ngā matū whakapakeke i te pakari o ngā kirihou, ā, ko ōna āhuatanga miihini e tohuhia ana e ngā āhuatanga piko me te kume, kaua e te ātete pānga.
Ko ngā āhuatanga o te CPE e pā ana ki te nui o te chlorine. I ngā wā o mua, ko te CPE kei roto ko te 35% chlorine nā te mea he pai ake te ngāwari o te rapa me te hototahitanga pai. Hei tāpiri, ka taea hoki te whakamahi i ngā whakaū wera PVC noa mō te CPE me te kore e hiahiatia he tāpiri atu i ētahi atu whakaū motuhake. He rite te MBS ki te ABS, he hototahitanga pai ki te PVC, ā, ka taea te whakamahi hei whakarerekē pānga mō te PVC. Heoi, i roto i ngā whakatakotoranga ABS me te MBS, nā te kore e ātete ki te huarere, ko te nuinga o ēnei e whakamahia ana mō ngā hua o roto, ā, ka taea te whakamahi i te MBS mō ngā hua āhua mārama ki te mārama.
Ko tā mātou kamupene e arotahi ana ki te rangahau me te whanaketanga, te whakaputa, me te hoko i ngā hua whakarerekētanga kirihou PVC. Ko ngā hua e whakaputaina ana e te kamupene ko te whakarerekētanga tukatuka pānga ACR, te whakarerekētanga pānga MBS, me te polyethylene chlorine, e whakamahia ana hei whakapai ake i te mahi tukatuka, te kaha pānga, me te pakari pāmahana-iti o te tukatuka kirihou PVC. He whānuitia te whakamahinga o ngā hua a te kamupene i roto i ngā mara pēnei i ngā paipa, ngā rauemi hanga, te whakahāngai werohanga, ngā hua pupuhi, me ētahi atu.
I ngā tau tata nei, kua piki haere te haumitanga a te kamupene ki te rangahau me te whanaketanga o ngā tāpiringa rapa me te ABS me te hangarau i ia tau. Ahakoa te tipu rua o te haumitanga rangahau me te whanaketanga katoa me te kaha, kua arotauhia te hanganga o te haumitanga rangahau me te whanaketanga. Mō ngā taputapu, kua hokona e te kamupene ngā raina whakaputa aunoa matatau o te ao me ngā taputapu whakamātautau, me te whakapau kaha ki te whakawhanake i ngā hua me ngā taumata matatau o te ao. Ko ngā rauemi mata e hiahiatia ana mō te whakaputa ka hokona mai i ngā kaihanga hangarau o te ao, me te kounga pumau me te pono. I tēnei wā, e rima ngā kaimahi R&D matua o te kamupene, neke atu i te 20 ngā kaimahi R&D waenga, me te neke atu i te 20 ngā rōpū mahi tahi. Kua whakawhanakehia tahi e te kamupene tētahi hua hou me ngā umanga rongonui o tāwāhi, ka taea te whakaoti rapanga o ngā kai kirihou tuku iho me ngā utu nui, ā, kua tutuki ngā hua nui.
