HDPEpaub txog nws qhov siab zog-rau-qhov sib piv.Qhov ceev ntawm HDPE tuaj yeem nyob ntawm 930 txog 970 kg / m3.Txawm hais tias qhov ntom ntawm HDPE tsuas yog marginally siab dua li ntawm cov polyethylene low-density, HDPE muaj me ntsis branching, muab nws muaj zog intermolecular rog thiab tensile zog tshaj LDPE.Qhov sib txawv ntawm lub zog ntau dua qhov sib txawv ntawm qhov ntom ntom, muab HDPE muaj zog dua qhov tshwj xeeb.Nws kuj yog qhov nyuaj thiab ntau dua opaque thiab tuaj yeem tiv taus qhov kub thiab txias (120 ° C / 248 ° F rau lub sijhawm luv).High-density polyethylene, tsis zoo li polypropylene, tsis tuaj yeem tiv taus ib txwm xav tau autoclaving tej yam kev mob.Qhov tsis muaj ceg yog ua kom ntseeg tau los ntawm kev xaiv tsim nyog ntawm cov catalyst (xws li Ziegler-Natta catalysts) thiab cov xwm txheej tshwm sim.
