ʻO ka polyethylene haʻahaʻa haʻahaʻa (LDPE) he resin synthetic me ka hoʻohana ʻana i ke kaʻina hana kiʻekiʻe ma o ka polymerization radical manuahi o ka ethylene a no laila ua kapa ʻia ʻo ia ʻo "high-pressure polyethylene".No ka mea he nui nā lālā lōʻihi a pōkole o kāna kaulahao molekala, ʻoi aku ka liʻiliʻi o ka LDPE ma mua o ka polyethylene kiʻekiʻe (HDPE) a ʻoi aku ka haʻahaʻa.Hōʻike ia i ka māmā, hiki ke maʻalahi, maikaʻi ke kūpaʻa hau a me ka hopena.Paʻa kemika ʻo LDPE.He kūpaʻa maikaʻi kona i nā waikawa (koe naʻe nā waikawa oxidizing ikaika), alkali, paʻakai, nā waiwai insulation uila maikaʻi loa.He haʻahaʻa kona komo ʻana i ka mahu.Loaʻa i ka LDPE ka wai kiʻekiʻe a me ka hana maikaʻi.He kūpono ia no ka hoʻohana ʻana i nā ʻano hana hana thermoplastic a pau, e like me ka hoʻoheheʻe ʻana, ka hoʻoheheʻe extrusion, ka hoʻoheheʻe ʻana, ka rotomolding, ka uhi ʻana, ka puaʻa, ka thermoforming, ka welding hot-jet a me ka welding thermal.
