Polyethylene imakhala ndi kukhazikika kwamankhwala ndipo imatha kukana kuchepetsedwa kwa nitric acid, kutsitsa sulfuric acid ndi hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, acetic acid, ammonia, amine, hydrogen peroxide, sodium hydroxide, potaziyamu hydroxide ndi mayankho ena kutentha kwa chipinda.Koma sikugonjetsedwa ndi dzimbiri zamphamvu za okosijeni, monga fuming sulfuric acid, concentrated nitric acid, chromic acid ndi sulfuric acid mix.Pa kutentha kwa chipinda, zosungunulira zimatulutsa pang'onopang'ono kukokoloka kwa polyethylene, ndipo pa 90 ~ 100 ℃, anaikira sulfuric acid ndi anaikira nitric asidi mwamsanga kukokera polyethylene, kupangitsa kuonongeka kapena decomposed.Polyethylene n'zosavuta chithunzi makutidwe ndi okosijeni, matenthedwe makutidwe ndi okosijeni, ozoni kuwonongeka, zosavuta kunyonyotsoka pansi zochita za ultraviolet kuwala, mpweya wakuda ali kwambiri kuwala zotchinga zotsatira pa polyethylene.Zochita monga kuwoloka, kuthyola unyolo ndi kupanga magulu osakanizidwa amatha kuchitika pambuyo pa ma radiation.

Polyethylene chingwe ndi alkane inert polima ndipo ali wabwino mankhwala stability.At firiji kutentha, asidi, zamchere, mchere amadzimadzi njira dzimbiri kukana, koma osati amphamvu oxidant monga fuming sulfuric acid, anaikira nitric asidi ndi chromic acid.Polyethylene insoluble mu ambiri solvents pansipa. 60 ℃, koma ndi aliphatic hydrocarbon, mafuta onunkhira a hydrocarbon, halogenated hydrocarbon ndi kukhudzana kwanthawi yayitali kumatupa kapena kusweka.

Chingwe cha polyethylene chimapangidwa ndi polyethylene, polyethylene chifukwa cha kupsinjika kwa chilengedwe (mankhwala ndi mawotchi) ndizovuta kwambiri, ukalamba wa kutentha ndi woipa kuposa kapangidwe ka mankhwala a polima ndi strip. kupanga filimu, ma CD zipangizo, muli, mapaipi, monofilament, waya ndi chingwe, zofunika tsiku ndi tsiku, etc., ndipo angagwiritsidwe ntchito monga mkulu pafupipafupi kutchinjiriza zipangizo kwa TV, radar, etc.Ndi chitukuko cha makampani petrochemical, kupanga wa polyethylene wakhala mofulumira kukula, mlandu pafupifupi 1/4 wa okwana kupanga mapulasitiki.Mu 1983, okwana dziko mphamvu yopanga polyethylene anali 24.65 mT, ndi mphamvu ya zomera akumanga anali 3.16 mT.Zotsatira zaposachedwa zowerengera mu 2011, mphamvu yopanga padziko lonse lapansi idafika 96 MT, njira yachitukuko yopanga polyethylene ikuwonetsa kuti kupanga ndi kugwiritsa ntchito pang'onopang'ono kukupita ku Asia, ndipo China ikukhala msika wofunikira kwambiri wogula.
