HDPE yog siv nyob rau hauv ntau yam kev siv thiab kev lag luam uas zoo heev cuam tshuam tsis kam, siab tensile zog, tsis tshua muaj noo noo nqus thiab tshuaj thiab corrosion kuj zog. Thiab PE muaj cov khoom rwb thaiv tsev zoo thiab yooj yim rau vuam.
HDPE dub ntawv yog ua los ntawm HDPE nrog cov xim tshwj xeeb. HDPE raw khoom yog dawb, dub yog ntxiv carbon dub. Lub luag haujlwm tseem ceeb ntawm carbon dub yog tiv thaiv ultraviolet, carbon dub tuaj yeem tiv thaiv ultraviolet kev puas tsuaj rau cov saw hlau molecular ntawm polyethylene. HDPE dub daim ntawv muab kev yooj yim rau kev siv cua qhib, tab sis kuj tuaj yeem muab faus rau siv, thaum ua tau raws li qhov yuav tsum tau ua ntawm kev noj qab haus huv.
