Polyethylene imafupikitsidwa kuti PE, yomwe ndi mtundu wa utomoni wa thermoplastic wopangidwa ndi polymerization ya ethylene. Mu mafakitale, imaphatikizaponso ma copolymer a ethylene ndi α-olefin pang'ono. Polyethylene ndi yopanda fungo, si poizoni, imamveka ngati sera, imakhala ndi kukana kutentha kochepa (kutentha kochepa komwe kungagwiritsidwe ntchito kumatha kufika -70 ~ 100 ℃), imakhala ndi kukhazikika kwabwino kwa mankhwala, ndipo imatha kupirira ma acid ndi alkali ambiri (osagonjetsedwa ndi okosijeni) Acid), yosasungunuka mu zosungunulira zonse kutentha kwa chipinda, imayamwa madzi ochepa, imateteza bwino magetsi; koma polyethylene imakhudzidwa kwambiri ndi kupsinjika kwa chilengedwe (mankhwala ndi zotsatira za makina), ndipo imakhala ndi kukana kofooka kwa kutentha. Makhalidwe a polyethylene amasiyana malinga ndi mitundu, makamaka kutengera kapangidwe ka mamolekyulu ndi kuchulukana. Njira zosiyanasiyana zopangira zingagwiritsidwe ntchito kupeza zinthu zokhala ndi makulidwe osiyanasiyana (0.91 ~ 0.96g / cm3). Polyethylene imatha kukonzedwa pogwiritsa ntchito njira zambiri zopangira thermoplastic (onani processing ya pulasitiki). Ili ndi ntchito zosiyanasiyana, makamaka popanga mafilimu, zotengera, mapaipi, monofilaments, mawaya ndi zingwe, zofunikira za tsiku ndi tsiku, ndi zina zotero, ndipo ingagwiritsidwe ntchito ngati zipangizo zotetezera kutentha kwambiri pa ma TV, ma radar, ndi zina zotero.
Mitundu ya PE:
(1) LDPE: polyethylene yotsika kwambiri, polyethylene yothamanga kwambiri
(2) LLDPE: polyethylene yotsika kwambiri
(3) MDPE: polyethylene yochuluka kwambiri, utomoni wa bimodal
(4) HDPE: polyethylene yochuluka kwambiri, polyethylene yotsika mphamvu
(5) UHMWPE: Polyethylene yolemera kwambiri ya molekyulu
(6) Polyethylene yosinthidwa: CPE, polyethylene yolumikizidwa (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (pulasitiki), EVA, ethylene-butene copolymer, ethylene-other olefin (monga octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer ( EAA, EMAA, EEA, EMA, EMMA, EMAH

Chitoliro chathuimapangidwa ndi zinthu za HDPE
