Nolosheenna, CPE iyo PVC si weyn ayaa loo isticmaalaa. Polyethylene-ka koloriinaysan waa walax polymer ah oo buuxa oo leh muuqaal budo cad, aan sun ahayn oo aan dhadhan lahayn, waxayna leedahay iska caabin cimilo oo aad u fiican, iska caabin ozone ah, iska caabin kiimiko iyo iska caabin gabowga. Waxqabad, oo leh iska caabin saliid oo wanaagsan, dib u dhac olol iyo sifooyin midabayn. Adkayn wanaagsan (wali dabacsan -30°C), iswaafajin wanaagsan oo lala yeesho agabka kale ee polymer-ka, iyo heerkul sare oo kala daadanaya. Polyethylene-ka koloriinaysan waa walax polymer ah oo laga sameeyay polyethylene-ka cufnaanta sare leh (HDPE) iyada oo loo marayo falcelin beddelka koloriinaysan. Sida laga soo xigtay qaab-dhismeedka iyo isticmaalka kala duwan, polyethylene-ka koloriinaysan waxaa loo qaybin karaa laba qaybood: polyethylene-ka koloriinaysan nooca resin-ka ah (CPE) iyo polyethylene-ka koloriinaysan nooca elastomer-ka ah (CM). Marka laga soo tago in keligiis la isticmaalo, resins-ka thermoplastic-ka waxaa sidoo kale lagu dari karaa polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), polystyrene (PS), ABS iyo xitaa polyurethane (PU). Warshadaha caagga, CPE waxaa loo isticmaali karaa caag gaar ah oo tayo sare leh, waxaana sidoo kale loo isticmaali karaa caagga ethylene-propylene (EPR), caagga butyl (IIR), caagga nitrile (NBR), polyethylene chlorosulfonated (CSM), iwm. Isku-darka caagga kale ayaa la isticmaalaa.
Sannadihii 1960-meeyadii, shirkadda Jarmalka ee Hoechst ayaa markii ugu horreysay si guul leh u horumarisay oo hirgelisay wax soo saarka warshadaha. Dalkaygu wuxuu bilaabay inuu horumariyo polyethylene-ka koloriinaysan dabayaaqadii 1970-meeyadii. "Isku-darka Joojinta Wajiga Biyaha ee Tiknoolajiyadda CPE" waxaa markii ugu horreysay si guul leh u horumariyay Machadka Cilmi-baarista Warshadaha Kiimikada ee Anhui, aaladaha wax soo saarka ee 500-1000t/a oo leh miisaanno kala duwan ayaa laga dhisay Wuhu, Anhui, Taicang, Jiangsu, iyo Weifang, Shandong.
Iska caabbinta saliidda ee CPE waa mid dhexdhexaad ah, kuwaas oo ay ka mid yihiin iska caabbinta saliidda ASTM No. 1 iyo saliidda ASTM No. 2 ay aad u fiican tahay, taas oo u dhiganta NBR; iska caabbinta saliidda ASTM No. 3 waa mid aad u fiican, ka fiican CR, taas oo u dhiganta CSM.
CPE waxay ka kooban tahay koloriin, oo leh sifooyin aad u fiican oo ka hortagga dabka waxayna leedahay astaamaha gubashada iyo ka hortagga daadinta. Waxaa lagu dari karaa ka hortagga dabka ku salaysan antimony, paraffin chlorine ku jira, iyo Al(OH)3 oo ku habboon saamiga si loo helo walxo ka hortagga dabka oo leh waxqabad aad u fiican oo ka hortagga dabka iyo kharash yar.
CPE ma aha sun, kama koobna biraha culus iyo PAHS, waxayna si buuxda u buuxisaa shuruudaha ilaalinta deegaanka.
CPE waxay leedahay waxqabad buuxa oo heer sare ah waxaana laga dhigi karaa alaab buuxisa shuruudaha waxqabadka kala duwan. CPE waxay leedahay awood farsamo oo wanaagsan, dheellitirka Mooney (ML121 1+4) wuxuu u dhexeeyaa 50-100, waxaana jira darajooyin badan oo laga dooran karo.
