HDPE feem ntau yog hais txog high-density polyethylene. High-density polyethylene (HDPE) yog cov hmoov dawb los yog granular khoom. degree; hardness, tensile zog thiab creep yog superior rau tsawg-density polyethylene; hnav tsis kam, hluav taws xob rwb thaiv tsev, toughness thiab txias kuj zoo dua; tshuaj stability yog zoo, insoluble nyob rau hauv tej organic hnyav ntawm chav tsev kub, acid-resistant, alkali thiab ntau yam ntsev; zaj duab xis muaj tsawg permeability rau dej vapor thiab huab cua, tsis tshua muaj dej nqus; kev laus tsis zoo, ib puag ncig kev nyuaj siab tawg kuj tsis zoo li qhov tsawg-density polyethylene, tshwj xeeb tshaj yog thermal oxidation yuav ua rau nws cov kev ua haujlwm poob qis, yog li cov resin yuav tsum tau ntxiv cov antioxidants thiab UV absorbers los txhim kho qhov tsis txaus. High-density polyethylene zaj duab xis muaj qhov kub thiab txias distortion kub nyob rau hauv kev ntxhov siab, yog li yuav tsum tau saib xyuas thaum siv nws.
