I-Polyethylene isifushanisiwe njenge-PE, okuwuhlobo lwe-thermoplastic resin eyenziwe nge-polymerization ye-ethylene.Embonini, kuhlanganisa nama-copolymers e-ethylene kanye nenani elincane le-α-olefin.I-Polyethylene ayinaphunga, ayinabo ubuthi, izwakala njengengcina, inokumelana nezinga lokushisa eliphansi kakhulu (izinga lokushisa elincane lokusetshenziswa lingafinyelela -70～-100℃), inokuqina okuhle kwamakhemikhali, futhi ingamelana nama-asidi amaningi nama-alkali (ayikwazi ukumelana nezakhiwo ze-oxidizing. I-Acid), engancibiliki kuma-solvents ejwayelekile ekamelweni lokushisa, ukumuncwa kwamanzi aphansi, ukufakwa kukagesi okuhle kakhulu;kodwa i-polyethylene izwela kakhulu ekucindezelekeni kwemvelo (imiphumela yamakhemikhali nemishini), futhi inokumelana nokuguga okumpofu kokushisa.Izakhiwo ze-polyethylene ziyahlukahluka ezinhlotsheni kuya kwezinhlobo, ikakhulukazi kuye ngesakhiwo samangqamuzana nokuminyana.Izindlela ezihlukene zokukhiqiza zingasetshenziswa ukuze kutholwe imikhiqizo enokuminyana okuhlukile (0.91～0.96g/cm3).I-polyethylene ingacutshungulwa ngezindlela ezijwayelekile zokubumba ze-thermoplastic (bheka ukucubungula kwepulasitiki).Inezinhlobonhlobo zokusetshenziswa, ikakhulukazi ezisetshenziselwa ukwenza amafilimu, iziqukathi, amapayipi, ama-monofilaments, izintambo nezintambo, izidingo zansuku zonke, njll., futhi ingasetshenziswa njengezinto zokuvikela eziphakeme kakhulu zama-TV, ama-radar, njll.
Izinhlobo ze-PE:
(1) I-LDPE: i-polyethylene ene-low density, i-polyethylene yokucindezela okuphezulu
(2) I-LLDPE: i-linear low density polyethylene
(3) I-MDPE: i-polyethylene ephakathi nendawo, i-bimodal resin
(4) HDPE: high density polyethylene, low pressure polyethylene
(5) I-UHMWPE: I-polyethylene yesisindo samangqamuzana ephezulu kakhulu
(6) I-polyethylene eguquliwe: I-CPE, i-polyethylene exhunywe ngokuphambene (PEX)
(7) I-Ethylene copolymer: i-ethylene-propylene copolymer (ipulasitiki), i-EVA, i-ethylene-butene copolymer, i-ethylene-enye i-olefin (njenge-octene POE, i-cyclic olefin) i-copolymer, i-ethylene-unsaturated ester copolymer, EAA, EAA, EAA, EMMA, EMAH
