Ko te HDPE e tautuhia ana e te mātotoru nui atu, e ōrite rānei ki te 0.941 g/cm3. He iti te peka o te HDPE, nō reira he kaha ake ngā kaha i waenga i ngā ngota me te kaha kume. Ka taea te whakaputa i te HDPE mā ngā whakakorikori chromium/silica, ngā whakakorikori Ziegler-Natta, ngā whakakorikori metallocene rānei. Ko te kore peka ka whakaritea mā te whiriwhiri tika i te whakakorikori (hei tauira, ngā whakakorikori chromium, ngā whakakorikori Ziegler-Natta rānei) me ngā tikanga tauhohenga.
E whakamahia ana te HDPE i roto i ngā hua me ngā takai pēnei i ngā ipu miraka, ngā pounamu hopi horoi, ngā ipu pata, ngā ipu para me ngā paipa wai. E whakamahia whānuitia ana hoki te HDPE i roto i te hanga ahi ahi. I roto i ngā ngongo rerekē te roa (i runga i te rahi o te pū), e whakamahia ana te HDPE hei whakakapi mō ngā ngongo moata kātene kua tukuna mō ngā take matua e rua. Tuatahi, he nui ake te haumaru i ngā ngongo kātene kua tukuna nā te mea mēnā ka hē te anga ka pahū i roto i te ("ipu putiputi") o te ngongo HDPE, e kore te ngongo e pakaru. Ko te take tuarua he mea ka taea te whakamahi anō, ā, ka taea e ngā kaihoahoa te hanga i ngā whata moata pupuhi maha. Kāore ngā tohunga ahi ahi e whakahē i te whakamahinga o ngā ngongo PVC i roto i ngā ngongo moata nā te mea ka pakaru pea, ka tukuna he maramara kirihou ki ngā kaimātakitaki pea, ā, e kore e puta i roto i ngā hihi-X.
