Polyethylene waxaa loo soo gaabiyaa sida PE, oo ah nooc ka mid ah resin thermoplastic oo lagu sameeyay polymerization of ethylene.Warshadaha, waxa kale oo ka mid ah copolymer-yaasha ethylene iyo xaddi yar oo α-olefin ah.Polyethylene waa mid aan ur lahayn, aan sun ahayn, waxay dareemeysaa sidii dhuxul, waxay leedahay iska caabin heerkul hooseeya oo aad u fiican (heerkulka isticmaalka ugu yar wuxuu gaari karaa -70 ℃ - 100 ℃), wuxuu leeyahay xasillooni kiimiko oo wanaagsan, wuxuuna u adkeysan karaa inta badan asiidhyada iyo alkaliska ) Acid), oo aan milmin guud ahaan dareeraha heerkulka qolka, nuugista biyaha hooseeya, korantada korantada ee ugu fiican;laakiin polyetylenku aad ayuu ugu nugul yahay diiqada deegaanka (saamaynta kiimikaad iyo farsamada), waxayna leedahay iska caabin gabowga oo liita.Astaamaha polyetylenku way ku kala duwan yihiin noocyada, inta badan waxay ku xidhan tahay qaabka molecular iyo cufnaanta.Hababka wax soo saarka kala duwan ayaa loo isticmaali karaa si loo helo badeecooyin cufnaan kala duwan leh (0.91-0.96g/cm3).Polyethylene waxaa lagu farsamayn karaa hababka qaabaynta heerkulbeegga guud (eeg habaynta balaastikada).Waxa ay leedahay adeegsiyo kala duwan oo inta badan loo isticmaalo samaynta filimada, weelasha, tuubooyinka, monofilaments, fiilooyinka iyo fiilooyinka, baahiyaha maalinlaha ah, iwm.
Noocyada PE:
(1) LDPE: polyetylen cufnaanta hoose, polyetylen cadaadis sare
(2) LLDPE: polyetylen cufnaanta hoose ee toosan
(3) MDPE: cufnaanta dhexdhexaadka ah ee polyetylen, bimodal resin
(4) HDPE: polyetylen cufnaanta sare, polyetylen cadaadis hooseeya
(5) UHMWPE: polyetylen culeyskiisu aad u sareeyo
(6) Polyetylen la beddelay: CPE, polyetylen iskutallaab ah (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (caag), EVA, ethylene-butene kopolymer, ethylene-olefin kale (sida octene POE, cyclic olefin) EMMA, EMAH
