HDPE muaj qhov kub thiab txias tsis kam, tshuaj lom neeg ruaj khov, siab rigidity thiab toughness, thiab zoo mechanical zog. Cov cuab yeej dielectric thiab ib puag ncig kev ntxhov siab tawg kuj zoo. Lub hardness, tensile zog thiab creep khoom yog zoo dua li cov uas tsis muaj ntom polyethylene; Hnav tsis kam, hluav taws xob rwb thaiv tsev, toughness thiab txias tsis kam yog zoo, tab sis lawv yog me ntsis phem dua li tsawg ntom rwb thaiv tsev.
Zoo tshuaj stability, insoluble nyob rau hauv tej organic hnyav ntawm chav tsev kub, thiab resistant rau acid, alkali thiab ntau yam ntsev; Lub membrane muaj tsawg permeability rau dej vapor thiab huab cua thiab tsis tshua muaj dej nqus; Kev laus ua haujlwm tsis zoo, thiab ib puag ncig kev sib tsoo tsis zoo yog qhov tsis zoo ntawm cov polyethylene tsawg, tshwj xeeb tshaj yog cov thermal oxidation yuav txo nws cov kev ua tau zoo.
Yog li ntawd, cov tshuaj antioxidants thiab ultraviolet absorbers yuav tsum tau ntxiv rau cov resin los txhim kho qhov no. Lub tshav kub deformation kub ntawm HDPE zaj duab xis nyob rau hauv kev ntxhov siab yog tsawg, uas yuav tsum tau muab sau tseg nyob rau hauv daim ntawv thov.
