Mu buzima bwacu, CPE na PVC birushaho gukoreshwa cyane. Polyethylene ifite chlorine ni polymer yuzuye ifite ifu yera, idahumanya kandi ntiryoha, kandi ifite ubushobozi bwo kurwanya ikirere, kurwanya ozone, kurwanya imiti no kurwanya gusaza. Ikora neza, ifite ubushobozi bwo kurwanya amavuta, idashobora gutwika umuriro no kugira ibara ryiza. Ifite ubushobozi bwo gukomera (iracyari yoroshye kuri -30°C), ihura neza n'ibindi bikoresho bya polymer, kandi irangirika cyane. Polyethylene ifite chlorine ni polymer ikozwe muri polyethylene ifite ubucucike bwinshi (HDPE) binyuze mu buryo bwo gusimbuza chlorine. Dukurikije imiterere n'imikoreshereze itandukanye, polyethylene ifite chlorine ishobora kugabanywamo ibyiciro bibiri: polyethylene ifite chlorine yo mu bwoko bwa resin (CPE) na polyethylene ifite chlorine yo mu bwoko bwa elastomer (CM). Uretse gukoreshwa byonyine, resins za thermoplastic zishobora kandi kuvangwa na polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS ndetse na polyurethane (PU). Mu nganda zikora kabutura, CPE ishobora gukoreshwa nk'umupira wihariye ukora neza kandi w'ubuziranenge, kandi ishobora no gukoreshwa na ethylene-propylene rubber (EPR), butyl rubber (IIR), nitrile rubber (NBR), chlorosulfonated polyethylene (CSM), n'ibindi. Hari izindi mvange za kabutura zikoreshwa.
Mu myaka ya 1960, isosiyete y’Abadage ya Hoechst yateje imbere umusaruro w’inganda ikanawugeraho. Igihugu cyanjye cyatangiye gukora polyethylene ifite chlorine mu mpera za 1970. "Aqueous Phase Suspension Synthesis of CPE Technology" yatejwe imbere bwa mbere n’Ikigo cy’Ubushakashatsi ku Nganda z’Ubutasi cya Anhui, kandi ibikoresho bitanga umusaruro bifite toni 500-1000/a bifite ibipimo bitandukanye byubatswe muri Wuhu, Anhui, Taicang, Jiangsu, na Weifang, muri Shandong.
Ubudahangarwa bw'amavuta bwa CPE buri hagati, muri bwo harimo ubudahangarwa bw'amavuta ya ASTM No. 1 na ASTM No. 2, bingana na NBR; ubudahangarwa bw'amavuta ya ASTM No. 3 ni bwiza cyane, kurusha CR, bingana na CSM.
CPE irimo chlorine, ifite ubushobozi bwiza bwo kudatwika no kudatonyanga. Ishobora guhuzwa n'ikoreshwa rya antimoni mu gutwika, parafini irimo chlorine, na Al (OH)3 mu gipimo gikwiye kugira ngo haboneke ibikoresho bigabanya umuriro bifite ubushobozi bwiza bwo kudatwika no kugabanuka kw'ibiciro.
CPE ntabwo ari uburozi, ntabwo irimo ibyuma biremereye na PAHS, kandi yujuje ibisabwa byose ku kurengera ibidukikije.
CPE ifite ubushobozi bwo kuzuza ibintu byinshi kandi ishobora gukorwamo ibicuruzwa byujuje ibisabwa bitandukanye. CPE ifite ubushobozi bwo gutunganya neza, ubushyuhe bwa Mooney (ML121 1+4) buri hagati ya 50-100, kandi hari amanota menshi yo guhitamo.
