O le Polyethylene ua faapuupuuina o le PE, o se ituaiga resin thermoplastic e faia e ala i le polymerization o le ethylene. I totonu o pisinisi, e aofia ai foi copolymers o le ethylene ma sina vaega itiiti o le α-olefin. E leai se manogi o le Polyethylene, e le oona, e pei o le wax, e matua tete'e atu i le vevela maualalo (o le vevela maualalo e mafai ona o'o atu i le -70～-100℃), e lelei le mautu o vaila'au, ma e mafai ona tete'e atu i le tele o acids ma alkalis (e le tete'e atu i meatotino oxidizing) Acid), e le solo i solvents lautele i le vevela o le potu, e itiiti le mitiia o le vai, e sili ona lelei le insulation eletise; ae o le polyethylene e matua maaleale lava i le siosiomaga (aafiaga o vaila'au ma masini), ma e le lelei le tete'e atu i le vevela o le matua. E eseese meatotino o le polyethylene mai lea ituaiga i lea ituaiga, e faalagolago tele lava i le fausaga o le molecular ma le mafiafia. E mafai ona fa'aogaina auala eseese o gaosiga e maua ai oloa e eseese mafiafia (0.91～0.96g/cm3). E mafai ona fa'agasolo le Polyethylene e ala i auala lautele o le fa'afoliga thermoplastic (tagai i le fa'agasologa o le palasitika). E tele ona faʻaaogāga, e masani ona faʻaaogā e fai ai ata tifaga, koneteina, paipa, monofilaments, uaea ma uaea, mea e manaʻomia i aso faisoo, ma isi mea, ma e mafai ona faʻaaogāina o ni mea e faʻavevela ai le ea i le tele o taimi mo TV, radar, ma isi mea.
Ituaiga o PE:
(1) LDPE: polyethylene maualalo le mafiafia, polyethylene maualuga le mamafa
(2) LLDPE: polyethylene maualalo le mafiafia laina
(3) MDPE: polyethylene mafiafia feololo, resin bimodal
(4) HDPE: polyethylene maualuga le mafiafia, polyethylene maualalo le mamafa
(5) UHMWPE: Polyethylene mamafa molekiula maualuga tele
(6) Polyethylene ua suia: CPE, polyethylene ua feso'ota'i fa'atasi (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (palasitika), EVA, ethylene-butene copolymer, ethylene-isi olefin (e pei o le octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer (EAA, EMAA, EEA, EMA, EMMA, EMAH
