Ua wehewehe ʻia ʻo HDPE e kahi density o ʻoi aku a like paha me 0.941 g/cm3. He haʻahaʻa ke kekelē o ka lālā ʻana o HDPE a no laila ʻoi aku ka ikaika o nā ikaika intermolecular a me ka ikaika tensile. Hiki ke hana ʻia ʻo HDPE e nā mea hoʻoulu chromium/silica, nā mea hoʻoulu Ziegler-Natta a i ʻole nā mea hoʻoulu metallocene. ʻO ka nele o ka lālā ʻana e hōʻoia ʻia e kahi koho kūpono o ka mea hoʻoulu (e like me nā mea hoʻoulu chromium a i ʻole nā mea hoʻoulu Ziegler-Natta) a me nā kūlana hopena.
Hoʻohana ʻia ʻo HDPE i nā huahana a me nā ʻōpala e like me nā ʻōmole waiū, nā ʻōmole detergent, nā ʻōmole margarine, nā ipu ʻōpala a me nā paipu wai. Hoʻohana nui ʻia ʻo HDPE i ka hana ʻana i nā mea puhi ahi. I loko o nā paipu o ka lōʻihi like ʻole (ma muli o ka nui o ka ordnance), hoʻohana ʻia ʻo HDPE ma ke ʻano he pani no nā paipu mortar pepa i hāʻawi ʻia no nā kumu nui ʻelua. ʻO ka mea mua, ʻoi aku ka palekana ma mua o nā paipu pepa i hāʻawi ʻia no ka mea inā hana hewa kahi pūpū a pahū i loko ("ipu pua") kahi paipu HDPE, ʻaʻole e haki ka paipu. ʻO ke kumu ʻelua, hiki ke hoʻohana hou ʻia e hiki ai i nā mea hoʻolālā ke hana i nā ʻūlū mortar pana he nui. Hoʻopale nā kānaka Pyrotechnicians i ka hoʻohana ʻana i nā paipu PVC i loko o nā paipu mortar no ka mea e haki pinepine ia, e hoʻouna ana i nā ʻāpana plastik i nā mea nānā, a ʻaʻole e ʻike ʻia i nā kukuna X.
