O le polyethylene e lelei le mautu o kemikolo ma e mafai ona tetee atu i le faʻafefeteina o le nitric acid, faʻafefete sulfuric acid ma soʻo se faʻatonuga o le hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amine, hydrogen peroxide, sodium hydroxide, potassium hydroxide ma isi fofo ile vevela potu.Ae e le mafai ona tetee atu i le corrosion oxidation malosi, e pei o le fuming sulfuric acid, concentrated nitric acid, chromic acid ma le sulfuric acid mixture.I le vevela o le potu, o le solvents o le a maua ai le solo malie o le polyethylene, ma i le 90 ~ 100℃, concentrated sulfuric acid ma concentrated nitric acid o le a vave ona faʻaumatia polyethylene, faʻaleagaina pe decomposed.Polyethylene e faigofie ona ata oxidation, vevela oxidation, ozone decomposition, faigofie ona faʻaleagaina i lalo o le gaioiga o le malamalama ultraviolet, carbon black o loʻo i ai se aafiaga lelei talipupuni malamalama i luga. polyethylene.Ta'i e pei ole feso'ota'iga, motusia filifili ma le fa'atupuina o vaega e le'i tumu e mafai ona tupu pe a uma le fa'avevela.

Polyethylene maea o le alkane inert polymer ma e lelei stability kemikolo.At vevela potu, acid, alkali, masima vai fofo corrosion tetee, ae le malosi oxidant e pei o le fuming sulfuric acid, concentrated nitric acid ma chromic acid.Polyethylene insoluble i soli lautele i lalo. 60 ℃, ae faʻatasi ai ma aliphatic hydrocarbon, hydrocarbon aromatic, halogenated hydrocarbon ma isi fesoʻotaʻiga umi o le a fula pe taʻe.

O le maea polyethylene o loʻo i ai le gaosiga o le polyethylene, o le polyethylene mo le faʻalavelave o le siosiomaga (kemisi ma le masini faʻainisinia) e matua maʻaleʻale, vevela vevela e sili atu le leaga nai lo le faʻaogaina o vailaʻau polymer ma le faʻaogaina o le fasi pepa. i le gaosiga o ata tifaga, mea faʻapipiʻi, pusa, paipa, monofilament, uaea ma uaea, mea e manaʻomia i aso uma, ma isi mea, ma e mafai ona faʻaaogaina e avea ma mea faʻapipiʻi maualuga mo TV, radar, ma isi. o le polyethylene ua vave ona atiae, e tusa ma le 1/4 o le aofaʻi o le gaosiga o palasitika. I le 1983, o le aofaʻi o le gaosiga o le polyethylene i le lalolagi o le 24.65 mT, ma le gafatia o le fale i lalo o le fausiaina o le 3.16 mT.O faʻamaumauga lata mai i le 2011, o le gaosiga o le lalolagi atoa na oʻo i le 96 MT, o le atinaʻeina o le gaosiga o le polyethylene o loʻo faʻaalia ai o le gaosiga ma le taumafaina o loʻo faasolosolo malie atu i Asia, ma o Saina ua avea ma maketi sili ona taua.
