Polyethylene waxaa loo soo gaabiyaa PE, kaas oo ah nooc ka mid ah resin thermoplastic ah oo laga sameeyay polymerization of ethylene. Warshadaha, waxa kale oo ku jira copolymers of ethylene iyo xaddi yar oo α-olefin ah. Polyethylene waa mid aan ur lahayn, ma sun ah, waxay dareemeysaa sida shamac, waxay leedahay iska caabin heerkul hoose oo aad u fiican (heerkulka ugu yar ee isticmaalka wuxuu gaari karaa -70~-100℃), waxay leedahay xasillooni kiimiko oo wanaagsan, waxayna u adkeysan kartaa inta badan asiidhyada iyo alkalis (uma adkaysan sifooyinka oksaydhka) Aashitada, oo aan ku milmin dareerayaasha guud heerkulka qolka, nuugista biyaha oo hooseeya, dahaarka korontada oo aad u fiican; laakiin polyethylene aad ayuu ugu nugul yahay cadaadiska deegaanka (saamaynta kiimikada iyo farsamada), waxayna leedahay iska caabin gabowga kulaylka oo liita. Sifooyinka polyethylene way kala duwan yihiin noocyada ilaa noocyada, inta badan waxay ku xiran tahay qaab-dhismeedka molecular iyo cufnaanta. Hababka wax soo saarka ee kala duwan ayaa loo isticmaali karaa in lagu helo alaabada leh cufnaan kala duwan (0.91~0.96g/cm3). Polyethylene waxaa lagu farsameyn karaa hababka wax lagu sameeyo thermoplastic guud (fiiri habka wax lagu sameeyo balaastikada). Waxay leedahay adeegsiyo kala duwan, oo inta badan loo isticmaalo sameynta filimada, weelasha, tuubooyinka, monofilaments, fiilooyinka iyo fiilooyinka, waxyaabaha maalinlaha ah, iwm., waxaana loo isticmaali karaa agab dahaadh oo heer sare ah oo loogu talagalay TV-yada, radar-yada, iwm.
Noocyada PE:
(1) LDPE: polyetylen cufnaan hooseeya, polyetylen cadaadis sare leh
(2) LLDPE: polyethylene cufnaanta hoose ee toosan
(3) MDPE: polyethylene cufnaan dhexdhexaad ah, resin bimodal ah
(4) HDPE: polyethylene cufnaan sare leh, polyethylene cadaadis hooseeya
(5) UHMWPE: Polyethylene-ka miisaanka molecular-ka aadka u sarreeya
(6) Polyethylene wax laga beddelay: CPE, polyethylene isku xiran (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (balaastig), EVA, ethylene-butene copolymer, ethylene-other olefin (sida octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer ( EAA, EMAA, EEA, EMA, EMMA, EMAH
