Polyethylene yakapfupikiswa sePE, inova rudzi rwe thermoplastic resin inogadzirwa ne polymerization ye ethylene. Muindasitiri, inosanganisirawo copolymers ye ethylene uye huwandu hushoma hwe α-olefin. Polyethylene haina hwema, haina chepfu, inonzwa sewakisi, ine resistance yakanaka kwazvo yekupisa yakaderera (tembiricha shoma inoshandiswa inogona kusvika -70 ~ 100 ℃), ine kugadzikana kwakanaka kwemakemikari, uye inogona kutsungirira akawanda maacids uye alkalis (haigoni kuoxidizing properties) Acid), isinganyungudike mu solvents yakawanda patembiricha yemumba, inonyungudika mvura shoma, inonyungudutsa zvakanaka mumagetsi; asi polyethylene inonzwa zvakanyanya kushushikana kwezvakatipoteredza (makemikari uye mhedzisiro yemakanika), uye haina resistance yakanaka yekukwegura kwekupisa. Hunhu hwe polyethylene hunosiyana kubva kumarudzi kusvika kumarudzi, kunyanya zvichienderana nechimiro chemamorekuru uye density. Nzira dzakasiyana dzekugadzira dzinogona kushandiswa kuwana zvigadzirwa zvine densities dzakasiyana (0.91 ~ 0.96g / cm3). Polyethylene inogona kugadziriswa nenzira dzakawanda dze thermoplastic molding (ona plastic processing). Inoshandiswa zvakasiyana-siyana, inonyanya kushandiswa kugadzira mafirimu, magaba, mapaipi, monofilaments, waya netambo, zvinodiwa zuva nezuva, nezvimwewo, uye inogona kushandiswa sezvinhu zvinodzivirira kupisa maTV, ma radar, nezvimwewo.
Mhando dzePE:
(1) LDPE: polyethylene yakaderera, polyethylene ine pressure yakakwira
(2) LLDPE: polyethylene ine huwandu hwakaderera
(3) MDPE: polyethylene ine huwandu hwepakati, resin ye bimodal
(4) HDPE: polyethylene ine huwandu hwakawanda, polyethylene ine pressure yakaderera
(5) UHMWPE: Polyethylene ine huremu hwakawanda kwazvo
(6) Polyethylene yakagadziridzwa: CPE, polyethylene yakabatana (PEX)
(7) Ethylene copolymer: ethylene-propylene copolymer (purasitiki), EVA, ethylene-butene copolymer, ethylene-other olefin (yakadai se octene POE, cyclic olefin) copolymer, ethylene-unsaturated ester copolymer ( EAA, EMAA, EEA, EMA, EMMA, EMAH
