Ko te whakarāpopototanga o te Polyethylene ko te PE, he momo kapia thermoplastic i hangaia mā te polymerization o te ethylene. I roto i te ahumahi, kei roto hoki ngā copolymers o te ethylene me te iti o te α-olefin. Kāore he kakara o te Polyethylene, kāore he paitini, he rite te ahua ki te ware pi, he ātete pai ki te pāmahana iti (ka taea e te pāmahana iti rawa te tae ki te -70～-100℃), he pai te pumau matū, ā, ka taea te tu atu ki te nuinga o ngā waikawa me ngā kawakore (kāore e ātete ki ngā āhuatanga waikura) waikawa), kāore e rewa i roto i ngā whakarewa whānui i te pāmahana rūma, he iti te mimiti wai, he pai te whakamarumaru hiko; engari he tino tairongo te polyethylene ki te ahotea taiao (ngā pānga matū me te miihini), ā, he iti te ātete ki te koroheketanga wera. He rerekē ngā āhuatanga o te polyethylene i ia momo, i runga i te hanganga ngota me te mātotoru. Ka taea te whakamahi i ngā tikanga whakaputa rerekē hei whiwhi hua me ngā mātotoru rerekē (0.91～0.96g/cm3). Ka taea te tukatuka i te Polyethylene mā ngā tikanga whakahāngai thermoplastic whānui (tirohia te tukatuka kirihou). He whānuitia ōna whakamahinga, ko te nuinga he hanga kiriata, he ipu, he paipa, he monofilaments, he waea me ngā taura, he mea e hiahiatia ana i ia rā, me ētahi atu, ā, ka taea te whakamahi hei rauemi ārai auau-teitei mō ngā pouaka whakaata, ngā radar, me ētahi atu.
Ngā momo PE:
(1) LDPE: polyethylene iti te matotoru, polyethylene pēhanga teitei
(2) LLDPE: polyethylene iti-kiato raina
(3) MDPE: polyethylene kiato-waenga, kapia bimodal
(4) HDPE: polyethylene kiato teitei, polyethylene pēhanga iti
(5) UHMWPE: Polyethylene taumaha-tino teitei
(6) Polyethylene kua whakarerekētia: CPE, polyethylene kua honoa-whiti (PEX)
(7) Kopaira Ethylene: kopaira ethylene-propylene (kirihou), EVA, kopaira ethylene-butene, kopaira ethylene-ētahi atu olefin (pērā i te octene POE, cyclic olefin), kopaira ethylene-unsaturated ester (EAA, EMAA, EEA, EMA, EMMA, EMAH
