I-Polyethylene ifushaniswe ngokuthi i-PE, okuwuhlobo lwe-thermoplastic resin eyenziwe yi-polymerization ye-ethylene. Embonini, ihlanganisa nama-copolymer e-ethylene kanye nenani elincane le-α-olefin. I-Polyethylene ayinaphunga, ayinabo ubuthi, izwakala njenge-wax, inokumelana okuhle kakhulu nokushisa okuphansi (izinga lokushisa eliphansi lokusetshenziswa lingafinyelela ku--70 ~ 100 ℃), inokuqina okuhle kwamakhemikhali, futhi ingamelana nama-acid amaningi nama-alkali (ayimelani nezakhiwo ze-oxidizing) I-Acid), ayincibiliki ezinyibilikisini ezijwayelekile ekushiseni kwegumbi, ukumuncwa kwamanzi okuphansi, ukufakelwa kukagesi okuhle kakhulu; kodwa i-polyethylene iyazwela kakhulu ekucindezelekeni kwemvelo (imiphumela yamakhemikhali neyemishini), futhi inokumelana okuncane nokuguga kokushisa. Izakhiwo ze-polyethylene ziyahlukahluka kusuka ezinhlotsheni kuya ezinhlotsheni, ikakhulukazi kuye ngesakhiwo sama-molecule kanye nobuningi. Izindlela ezahlukene zokukhiqiza zingasetshenziswa ukuthola imikhiqizo enobukhulu obuhlukene (0.91 ~ 0.96g/cm3). I-Polyethylene ingacutshungulwa ngezindlela zokubumba ze-thermoplastic ezijwayelekile (bheka ukucutshungulwa kwepulasitiki). Inezindlela eziningi zokusebenzisa, ikakhulukazi ezisetshenziselwa ukwenza amafilimu, izitsha, amapayipi, ama-monofilaments, izintambo kanye nezintambo, izidingo zansuku zonke, njll., futhi ingasetshenziswa njengezinto zokuvikela ezivame kakhulu kuma-TV, ama-radar, njll.
Izinhlobo ze-PE:
(1) I-LDPE: i-polyethylene ephansi, i-polyethylene enomfutho ophezulu
(2) I-LLDPE: i-polyethylene eqondile ephansi
(3) i-MDPE: i-polyethylene enobukhulu obuphakathi, i-resin ye-bimodal
(4) I-HDPE: i-polyethylene enobuningi obuphezulu, i-polyethylene enomfutho ophansi
(5) UHMWPE: I-polyethylene enesisindo sama-molecule esiphezulu kakhulu
(6) I-polyethylene eguquliwe: i-CPE, i-polyethylene exhumene (i-PEX)
(7) I-ethylene copolymer: i-ethylene-propylene copolymer (ipulasitiki), i-EVA, i-ethylene-butene copolymer, i-ethylene-other olefin (njenge-octene POE, i-cyclic olefin) copolymer, i-ethylene-unsaturated ester copolymer (i-EAA, i-EMAA, i-EEA, i-EMA, i-EMMA, i-EMAH

Ipayipi lethuyenziwe ngezinto ze-HDPE
