IKei roto ko te hanga paninga, arai me ngā hua e ātete ana ki te waikura me te ātete wera, e whakamahia ana hei whakarerekētanga mō te PVC, ABS me ētahi atu polyolefins, te hanga rauemi papa kore e mura me te ātete matū, te hiako horihori, te kirihou pahuka, ngā kiriata, ngā pereti, ngā rauemi whakakikoruatia, ngā paninga taura me te waea, me ētahi atu, me te whakapai ake i te pakari me te ātete mura o ngā piripiri.
He rauemi pūmua kua whakakīia ki te hauota (CPE) he rite ki te paura mā te āhua, kāore he paitini, kāore hoki he kakara. He tino pai tōna ātete ki te huarere, te ātete ki te ozone, te ātete ki ngā matū, me te ātete ki te koroheketanga, tae atu ki te ātete hinu, te ātete mura, me ngā āhuatanga tae. He pakari pai (he ngāwari tonu i te -30℃), he pai te hototahitanga ki ētahi atu rauemi polymer, me te pāmahana pirau teitei. Ko te tikanga wai o te polyethylene chlorinated te mea e whakamahia whānuitia ana, he iti ngā utu whakaputa me te iti o te parahanga. Ko tētahi atu tikanga ko te tikanga whakatārewatanga, he mea kua pakeke ake, ā, ka taea te whakawhanake me te whakamahi i roto i te whare. He tere te tere whakamaroke. He mea whakamahi whānuitia i roto i ngā tāke rokiroki me ngā hanganga maitai hei whakapai ake i te haumaru hanga. Ko ngā tauira whare o te polyethylene chlorinated (CPE) ka tautuhia whānuitia mā ngā tau pēnei i te 135A, 140B, 239C, me ētahi atu, ko te mati tuatahi 1 me te 2 e tohu ana i te tioata toenga (uara TAC), ko te 1 e tohu ana i te uara TAC i waenga i te 0-10%, ko te 2 e tohu ana i te uara TAC o te 10%, ko te mati tuarua me te tuatoru e tohu ana i te ihirangi chlorine, pēnei i te 35 e tohu ana i te ihirangi chlorine o te 35%, ā, ko te mati whakamutunga ko te reta ABC, e whakamahia ana hei tohu i te taumaha ngota o te rauemi mata PE, ko A te mea nui rawa atu, ko C te mea iti rawa. Ko te rauemi polyethylene chlorine (CPE) momo A te taumaha ngota teitei rawa atu me te matotoru rewa teitei, ā, ko tōna matotoru te mea tino hototahi ki te PVC. Ko tōna pānga marara pai rawa atu i roto i te PVC, ā, ka taea te hanga i tētahi āhua marara rite ki te whatunga tino pai. Nō reira, ko te rauemi momo CPE A te nuinga o te wā ka tīpakohia hei whakarerekētanga mō te PVC. Waea me te taura (ngā taura maina waro, ngā waea kua tohua i roto i ngā paerewa UL me VDE), ngā ngongo rapa waipēhi, ngā ngongo rapa motuka, te rīpene, ngā pereti rapa, te whakarerekētanga paipa kōtaha PVC, ngā rauemi aukume, te whakarerekētanga ABS, me ētahi atu. Ina koa ko te whanaketanga o te umanga waea me te taura, me te umanga hanga wāhanga motuka, kua akiaki i te hiahia kai mō te polyethylene chlorine i ahu mai i te rapa. Ko te polyethylene chlorine momo rapa he rapa hanga motuhake me te mahi whānui tino pai, te ātete ki te wera me te hāora ozone tawhito, me te ātete mura pai.
