Polyethylene muaj qhov qis zoo tshaj plaws - qhov kub ua haujlwm (tsawg kawg ntawm kev ua haujlwm kub, thiab kev tawm tsam zoo tshaj plaws), thiab cov pa hluav taws xob feem ntau (tsis oxidizing acids). Nws yog insoluble nyob rau hauv cov kuab cua sov nyob ntawm chav tsev kub, muaj cov dej nqus dej tsawg, thiab muaj hluav taws xob rwb thaiv tsev. Txawm li cas los xij, Polyethylene yog rhiab heev rau kev ntxhov siab ib puag ncig (tshuaj lom neeg thiab tshuab) thiab muaj kev txom nyem thermal tsis kam. Cov yam ntxwv ntawm polyethylene sib txawv los ntawm ntau yam, feem ntau nyob ntawm nws cov qauv molecular thiab ntom. Cov txheej txheem sib txawv tuaj yeem tsim cov khoom lag luam nrog sib txawv (0.91 txog 0.96 g / cm³). Polyethylene tuaj yeem ua tiav siv cov qauv thermoplastic moulding txoj kev (saib plastics ua).
