HDPE yog txhais los ntawm qhov ceev ntawm ntau dua lossis sib npaug rau 0.941 g / cm3. HDPE muaj qib qis ntawm kev sib ceg thiab yog li muaj zog dua intermolecular zog thiab lub zog tensile. HDPE tuaj yeem tsim los ntawm chromium / silica catalysts, Ziegler-Natta catalysts lossis metallocene catalysts. Qhov tsis muaj kev sib ceg yog ua kom ntseeg tau los ntawm kev xaiv cov catalyst tsim nyog (piv txwv li chromium catalysts lossis Ziegler-Natta catalysts) thiab cov xwm txheej tshuaj tiv thaiv.
HDPE siv rau hauv cov khoom thiab cov ntim khoom xws li cov khob mis nyuj, cov fwj tshuaj ntxuav tes, cov thoob margarine, cov thawv pov tseg thiab cov kav dej. HDPE kuj siv dav hauv kev tsim cov foob pob hluav taws. Hauv cov raj uas muaj ntau qhov ntev (nyob ntawm qhov loj ntawm cov riam phom), HDPE siv los hloov cov raj xa ntawv mortar uas muab los rau ob qho laj thawj tseem ceeb. Ib qho, nws muaj kev nyab xeeb dua li cov raj xa ntawv cardboard vim tias yog tias lub plhaub tsis ua haujlwm thiab tawg hauv ("lub lauj kaub paj") lub raj HDPE, lub raj yuav tsis tawg. Qhov laj thawj thib ob yog tias lawv siv tau dua uas tso cai rau cov neeg tsim qauv tsim ntau lub txee mortar. Cov kws kho phom tsis pom zoo siv cov raj PVC hauv cov raj xa ntawv mortar vim tias nws feem ntau tawg, xa cov yas me me rau cov neeg saib, thiab yuav tsis tshwm sim hauv X-rays.
