Polyethylene amafupikitsidwa ngati PE, womwe ndi mtundu wa utomoni wa thermoplastic wopangidwa ndi polymerization wa ethylene.M'makampani, amaphatikizanso ma copolymers a ethylene ndi pang'ono α-olefin.Polyethylene ndi yopanda fungo, yopanda poizoni, imakhala ngati sera, imakhala ndi kutentha kochepa kwambiri (kutentha kocheperako kumatha kufika -70～-100 ℃), imakhala ndi kukhazikika kwamankhwala abwino, ndipo imatha kupirira ma acid ambiri ndi alkalis (osagonjetsedwa ndi oxidizing katundu). Acid), osasungunuka mu zosungunulira zonse kutentha kwa firiji, kuyamwa kwamadzi otsika, kutsekemera kwambiri kwamagetsi;koma polyethylene imakhudzidwa kwambiri ndi kupsinjika kwa chilengedwe (mankhwala ndi mawotchi), ndipo imakhala ndi kukana kutentha kwaukalamba.Makhalidwe a polyethylene amasiyana mitundu ndi mitundu, makamaka kutengera kapangidwe ka maselo ndi kachulukidwe.Njira zosiyanasiyana zopangira zitha kugwiritsidwa ntchito kupeza zinthu zokhala ndi makulidwe osiyanasiyana (0.91 ~ 0.96g/cm3).Polyethylene imatha kukonzedwa ndi njira zonse zopangira thermoplastic (onani mapulasitiki apulasitiki).Zili ndi ntchito zosiyanasiyana, zomwe zimagwiritsidwa ntchito popanga mafilimu, zotengera, mapaipi, monofilaments, mawaya ndi zingwe, zofunikira za tsiku ndi tsiku, ndi zina zotero, ndipo zingagwiritsidwe ntchito ngati zipangizo zotetezera ma TV, ma radar, etc.
Mitundu ya PE:
(1) LDPE: otsika osalimba polyethylene, kuthamanga kwambiri polyethylene
(2) LLDPE: polyethylene yotsika kwambiri
(3) MDPE: polyethylene yapakatikati, utomoni wa bimodal
(4) HDPE: polyethylene yapamwamba kwambiri, polyethylene yotsika kwambiri
(5) UHMWPE: Wokwera kwambiri molekyulu yolemera polyethylene
(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, EAA, EAA, EAA, EAA EMMA, EMA

Pipette yathuamapangidwa ndi zinthu za HDPE
