I roto i tō tātou ao, ka nui haere te whakamahinga o te CPE me te PVC. Ko te polyethylene chlorinated he rauemi polymer kua kī, he āhua paura mā, kāore he paitini, kāore hoki he reka, ā, he tino pai te ātete ki te huarere, te ātete ki te ozone, te ātete ki ngā matū me te ātete ki te koroheketanga. He pai te mahi, he pai te ātete ki te hinu, te ātete ki te mura me ngā āhuatanga tae. He pakari pai (he ngāwari tonu i te -30°C), he pai te hototahi ki ētahi atu rauemi polymer, me te pāmahana pirau teitei. Ko te polyethylene chlorinated he rauemi polymer i hangaia mai i te polyethylene kiato teitei (HDPE) mā te tauhohenga whakakapinga chlorination. E ai ki ngā hanganga me ngā whakamahinga rerekē, ka taea te wehewehe i te polyethylene chlorinated ki ngā wāhanga e rua: te polyethylene chlorinated momo-reini (CPE) me te polyethylene chlorinated momo-elastomer (CM). Haunga te whakamahinga takitahi, ka taea hoki te whakaranu i ngā kapia thermoplastic ki te polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS me te polyurethane (PU). I roto i te umanga rapa, ka taea te whakamahi i te CPE hei rapa motuhake kounga teitei, ā, ka taea hoki te whakamahi me te rapa ethylene-propylene (EPR), te rapa butyl (IIR), te rapa nitrile (NBR), te polyethylene chlorosulfonated (CSM), me ētahi atu. Ka whakamahia ētahi atu ranunga rapa.
I ngā tau 1960, i angitu te whakawhanake me te whakatinana i te hanga ahumahi a te kamupene Tiamana Hoechst. I tīmata tōku whenua ki te whakawhanake i te polyethylene chlorinated i te mutunga o ngā tau 1970. I angitu te whakawhanake i te "Aqueous Phase Suspension Synthesis of CPE Technology" e te Anhui Chemical Industry Research Institute, ā, kua hangaia ngā taputapu whakaputa o te 500-1000t/a me ngā tauine rerekē ki Wuhu, Anhui, Taicang, Jiangsu, me Weifang, Shandong.
He toharite te ātete hinu o te CPE, ā, he tino pai te ātete ki te hinu ASTM Nama 1 me te hinu ASTM Nama 2, he rite ki te NBR; he tino pai te ātete ki te hinu ASTM Nama 3, he pai ake i te CR, he rite ki te CSM.
Kei roto i te CPE te chlorine, he āhuatanga pai rawa atu mō te ārai i te mura, ā, he āhuatanga anō hoki mō te mura me te ārai i te maturuturu. Ka taea te whakakotahi me te chlorine e hangai ana ki te ārai mura, te paraffin chlorine, me te Al(OH)3 i te ōwehenga tika hei whiwhi i tētahi rauemi ārai mura me te mahi ārai mura pai rawa atu, me te utu iti.
Kāore he paitini o te CPE, kāore he konganuku taumaha me ngā PAHS i roto, ā, e tutuki katoa ana i ngā whakaritenga tiaki taiao.
He tino pai te mahi whakakī a te CPE, ā, ka taea te hanga hei hua e tutuki ana i ngā whakaritenga mahi maha. He pai te tukatuka a te CPE, kei waenga i te 50-100 te matotoru o Mooney (ML121 1+4), ā, he maha ngā momo hei whiriwhiri māu.
