Ko te polyethylene he mea poto hei PE, he momo kapia thermoplastic i hangaia e te polymerization o te ethylene.I roto i te ahumahi, kei roto ano nga copolymers o te ethylene me te iti o te α-olefin.Ko te polyethylene he hongi, he kore-paitini, he rite ki te wax, he tino pai te atete ki te pāmahana iti (ko te iti rawa o te paanga o te whakamahinga ka eke ki te -70～-100 ℃), he pai te pumau matū, ka taea te tu ki te nuinga o nga waikawa me te kawakore (kaore e parea ki nga taonga whakahaora. ) Waikawa), karekau i roto i nga whakarewa whanui i te mahana o te rūma, he iti te whakauru wai, he pai te whakamaarama hiko;engari he tino tairongo te polyethylene ki te taumahatanga o te taiao (te matū me te mahi miihini), me te ngoikore o te wera wera.He rereke nga ahuatanga o te polyethylene i ia momo ki ia momo, i te nuinga o te waa i runga i te hanganga ngota me te kiato.Ka taea te whakamahi i nga tikanga whakaputa rereke hei tiki i nga hua he rereke te kiato (0.91～0.96g/cm3).Ka taea te tukatuka i te polyethylene e nga tikanga whakakikorua i te werawera (tirohia te tukatuka kirihou).He maha nga momo whakamahinga, ko te nuinga o te waa ki te hanga kiriata, ipu, paipa, monofilaments, waea me nga taura, nga mea e hiahiatia ana i ia ra, me etahi atu, ka taea te whakamahi hei taputapu whakamarumaru teitei mo nga pouaka whakaata, radar, aha atu.
Momo PE:
(1) LDPE: polyethylene iti kiato, polyethylene pēhanga teitei
(2) LLDPE: polyethylene iti kiato raina
(3) MDPE: polyethylene kiato reo, kapia bimodal
(4) HDPE: polyethylene kiato tiketike, polyethylene pēhanga iti
(5) UHMWPE: Te polyethylene te taumaha o te irapoi teitei
(6) polyethylene whakarerekē: CPE, polyethylene hono-whiti (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (kirihou), EVA, ethylene-butene copolymer, ethylene-other olefin (pērā i te octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer ( EAA, EMAA, EEA, EMA, EMMA, EMAH
