Polyethylene ua faapuupuuina pei PE, o se ituaiga o resini thermoplastic faia e polymerization o le ethylene.I totonu o alamanuia, e aofia ai foʻi copolymers o le ethylene ma sina vaega itiiti ole α-olefin.O le polyethylene e leai se manogi, e le o'ona, e pei o le ga'o, e matua'i maualalo le vevela o le vevela (o le la'ititi o le fa'aogaina o le vevela e mafai ona o'o i le -70-100 ℃), e lelei le mautu o vaila'au, ma e mafai ona tatalia le tele o acids ma alkalis (e le fa'asaoina i mea fa'ama'i. ) Acid), e le mafai ona faʻafefeteina i soʻo masani i le vevela o le potu, maualalo le faʻaogaina o le vai, sili ona lelei le faʻaogaina o le eletise;ae o le polyethylene e matua'i ma'ale'ale i le fa'amamafa o le si'osi'omaga (kemikolo ma le fa'ainisinia), ma e le lelei le vevela o le matua.O mea totino o le polyethylene e eseese mai lea ituaiga i lea ituaiga, aemaise lava i le fausaga mole mole ma le mamafa.E mafai ona fa'aogaina auala eseese e maua mai ai oloa e eseese densities (0.91～0.96g/cm3).O le polyethylene e mafai ona fa'agaoioia i auala masani fa'ameamea (silasila i le gaosiga o palasitika).O loʻo i ai le tele o faʻaoga, e masani ona faʻaaogaina e fai ai ata tifaga, koneteina, paipa, monofilaments, uaea ma uaea, mea e manaʻomia i aso uma, ma isi mea, ma e mafai ona faʻaaogaina e avea ma mea faʻapipiʻi maualuga mo TV, radar, ma isi.
Ituaiga PE:
(1) LDPE: polyethylene maualalo maualalo, polyethylene mamafa maualuga
(2) LLDPE: laina laina maualalo polyethylene
(3) MDPE: polyethylene medium density, resini bimodal
(4) HDPE: polyethylene maualuga maualuga, polyethylene maualalo maualalo
(5) UHMWPE: Polyethylene mamafa mole maualuga maualuga
(6) Suia polyethylene: CPE, polyethylene feso'ota'i (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (plastic), 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
