Kubomi bethu, i-CPE kunye ne-PVC zisetyenziswa kakhulu. I-polyethylene ekhlorini yi-polymer ezele yi-polyethylene enembonakalo yomgubo omhlophe, ayinatyhefu kwaye ayinancasa, kwaye inokumelana okuhle kwemozulu, ukumelana ne-ozone, ukumelana neekhemikhali kunye nokumelana nokwaluphala. Ukusebenza kakuhle, ukumelana neoyile elungileyo, ukubambezeleka komlilo kunye neempawu zombala. Ukuqina okuhle (kusaguquguquka kwi--30°C), ukuhambelana okuhle nezinye izinto ze-polymer, kunye nobushushu obuphezulu bokubola. I-polyethylene ekhlorini yi-polymer eyenziwe nge-polyethylene ephezulu (HDPE) ngokusebenzisa i-chlorination substitution reaction. Ngokwezakhiwo ezahlukeneyo kunye nokusetyenziswa, i-polyethylene ekhlorini inokwahlulwa ibe ziindidi ezimbini: i-resin-type chlorinated polyethylene (CPE) kunye ne-elastomer-type chlorinated polyethylene (CM). Ukongeza ekusetyenzisweni yodwa, ii-thermoplastic resins zinokudityaniswa ne-polyvinyl chloride (PVC), i-polyethylene (PE), i-polypropylene (PP), i-polystyrene (PS), i-ABS kunye ne-polyurethane (PU). Kwishishini lerabha, i-CPE ingasetyenziswa njengerabha ekhethekileyo esebenza kakuhle, ekumgangatho ophezulu, kwaye ingasetyenziswa nerabha ye-ethylene-propylene (EPR), irabha ye-butyl (IIR), irabha ye-nitrile (NBR), i-polyethylene ye-chlorosulfonated (CSM), njl. Kusetyenziswa ezinye iintlobo zerabha.
Kwiminyaka yoo-1960, inkampani yaseJamani iHoechst yaqala ukuphuhlisa ngempumelelo imveliso yemizi-mveliso. Ilizwe lam laqala ukuphuhlisa i-polyethylene ene-chlorine ngasekupheleni kweminyaka yoo-1970. I-"Aqueous Phase Suspension Synthesis of CPE Technology" yaphuhliswa ngempumelelo yi-Anhui Chemical Industry Research Institute, kwaye izixhobo zemveliso ze-500-1000t/a ezinezikali ezahlukeneyo zakhiwe eWuhu, eAnhui, eTaicang, eJiangsu, naseWeifang, eShandong.
Ukumelana neoyile ye-CPE kuphakathi, apho ukumelana neoyile ye-ASTM No. 1 kunye neoyile ye-ASTM No. 2 kugqwesileyo, okulingana ne-NBR; ukumelana neoyile ye-ASTM No. 3 kugqwesileyo, kungcono kune-CR, okulingana ne-CSM.
I-CPE ine-chlorine, eneempawu ezibalaseleyo zokungatshisi ilangatye kwaye ineempawu zokutsha kunye nokungatyibiliki. Ingadityaniswa ne-antimony-based flame retardant, i-chlorinated paraffin, kunye ne-Al(OH)3 ngomlinganiselo ofanelekileyo ukuze kufunyanwe izinto ezithintela ilangatye ezinentsebenzo egqwesileyo yokungatshisi ilangatye kunye nexabiso eliphantsi.
I-CPE ayinabungozi, ayinazo iintsimbi ezinzima kunye ne-PAHS, kwaye ihlangabezana ngokupheleleyo neemfuno zokhuseleko lokusingqongileyo.
I-CPE inomgangatho ophezulu wokuzalisa kwaye inokwenziwa ibe ziimveliso ezihlangabezana neemfuno ezahlukeneyo zokusebenza. I-CPE inokusebenza kakuhle, i-Mooney viscosity (ML121 1+4) iphakathi kwama-50-100, kwaye kukho amanqanaba amaninzi onokukhetha kuwo.
