M'moyo wathu, CPE ndi PVC zimagwiritsidwa ntchito kwambiri. Chlorinated polyethylene ndi zinthu zodzaza ndi polima zokhala ndi mawonekedwe oyera a ufa, zopanda poizoni komanso zopanda kukoma, ndipo zimakhala ndi kukana kwanyengo, kukana kwa ozoni, kukana mankhwala komanso kukana kukalamba. Magwiridwe, ndi kukana mafuta abwino, retardancy lawi ndi mitundu mitundu. Kulimba kwabwino (kumasinthasinthabe pa -30 ° C), kumagwirizana bwino ndi zida zina za polima, komanso kutentha kwakukulu kowola. Chlorinated polyethylene ndi polima wopangidwa kuchokera ku high-density polyethylene (HDPE) kudzera m'malo mwa chlorination. Malinga ndi mapangidwe ndi ntchito zosiyanasiyana, chlorinated polyethylene ikhoza kugawidwa m'magulu awiri: resin-mtundu wa chlorinated polyethylene (CPE) ndi elastomer-mtundu wa chlorinated polyethylene (CM). Kuphatikiza pa kugwiritsidwa ntchito kokha, ma resins a thermoplastic amathanso kusakanikirana ndi polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS komanso polyurethane (PU). M'makampani a mphira, CPE ingagwiritsidwe ntchito ngati mphira wapamwamba kwambiri, wapamwamba kwambiri, ndipo ingagwiritsidwe ntchito ndi mphira wa ethylene-propylene (EPR), mphira wa butyl (IIR), mphira wa nitrile (NBR), chlorosulfonated polyethylene ( CSM), etc. Zosakaniza zina za mphira zimagwiritsidwa ntchito.
M'zaka za m'ma 1960, kampani yaku Germany Hoechst idayamba kupanga bwino ndikuzindikira kupanga mafakitale. dziko langa linayamba kupanga chlorine polyethylene kumapeto kwa zaka za m'ma 1970. "Aqueous Phase Suspension Synthesis of CPE Technology" idapangidwa bwino ndi Anhui Chemical Viwanda Research Institute, ndipo zida zopanga 500-1000t/a ndi masikelo osiyanasiyana zamangidwa ku Wuhu, Anhui, Taicang, Jiangsu, ndi Weifang, Shandong. .
Kukana kwa mafuta a CPE ndi pafupifupi, pakati pa kukana kwa ASTM No. 1 mafuta ndi ASTM No. 2 mafuta ndi abwino kwambiri, omwe ali ofanana ndi NBR; kukana kwa ASTM No. 3 mafuta ndi abwino kwambiri, kuposa CR, omwe ali ofanana ndi CSM.
CPE ili ndi chlorine, yomwe ili ndi zinthu zabwino kwambiri zoletsa moto ndipo imakhala ndi mawonekedwe oyaka komanso odana ndi kudontha. Ikhoza kuphatikizidwa ndi antimoni-based flame retardant, chlorinated paraffin, ndi Al(OH)3 mu chiŵerengero choyenera kuti apeze zinthu zosagwira moto ndi ntchito yabwino kwambiri yoletsa moto komanso mtengo wotsika.
CPE si poizoni, ilibe zitsulo zolemera ndi PAHS, ndipo imakwaniritsa zofunikira zachitetezo cha chilengedwe.
CPE ili ndi ntchito yodzaza kwambiri ndipo imatha kupangidwa kukhala zinthu zomwe zimakwaniritsa zofunikira zosiyanasiyana. CPE ali processability wabwino, Mooney mamasukidwe akayendedwe (ML121 1+4) ndi pakati 50-100, ndipo pali sukulu zambiri zoti tisankhepo.
