HDPE yog txhais los ntawm qhov ceev ntawm ntau dua los yog sib npaug rau 0.941 g / cm3. HDPE muaj ib tug tsawg degree ntawm branching thiab yog li muaj zog intermolecular rog thiab tensile zog. HDPE tuaj yeem tsim los ntawm chromium / silica catalysts, Ziegler-Natta catalysts lossis metallocene catalysts. Qhov tsis muaj ceg yog ua kom ntseeg tau los ntawm kev xaiv tsim nyog ntawm cov khoom siv hluav taws xob (xws li chromium catalysts lossis Ziegler-Natta catalysts) thiab cov kev mob tshwm sim.
HDPE yog siv nyob rau hauv cov khoom thiab ntim xws li mis nyuj jugs, detergent fwj, margarine tubs, khib nyiab ntim thiab kav dej. HDPE kuj tseem siv dav hauv kev tsim cov foob pob hluav taws. Hauv cov raj ntawm qhov ntev sib txawv (nyob ntawm qhov loj ntawm cov khoom tawg), HDPE yog siv los hloov cov khoom siv los ntawm cov khoom siv rau ob qho laj thawj. Ib qho, nws muaj kev nyab xeeb ntau dua li cov khoom siv los ntawm cov hlab ntsha vim tias yog lub plhaub ua haujlwm tsis zoo thiab tawg hauv ("paj lauj kaub") lub raj HDPE, lub raj yuav tsis tawg. Qhov thib ob yog vim li cas yog tias lawv rov siv tau dua tso cai rau cov neeg tsim qauv tsim ntau yam tshuaj tua kab racks. Pyrotechnicians txwv tsis pub siv PVC tubing nyob rau hauv mortar raj vim hais tias nws nyiam tawg, xa shards ntawm yas ntawm cov neeg tuaj saib, thiab yuav tsis tshwm sim hauv X-rays.
