ʻO ke olonā polyethylene kaumaha molekala kiʻekiʻe loa (UHMWPE), i ʻike ʻia hoʻi ʻo ke olonā PE ikaika kiʻekiʻe, ʻo ia kekahi o nā olonā ʻenehana kiʻekiʻe ʻekolu ma ka honua i kēia lā (fiber kalapona, fiber aramid, a me ke olonā polyethylene kaumaha molekala kiʻekiʻe loa), a ʻo ia hoʻi ke olonā paʻakikī loa ma ka honua. He māmā ia e like me ka pepa a paʻakikī e like me ke kila, me ka ikaika he 15 manawa o ke kila, a ʻelua manawa o ke olonā kalapona a me ka aramid 1414 (fiber Kevlar). ʻO ia ka mea nui i kēia manawa no ka hana ʻana i nā ʻaʻahu pale pōkā.
ʻO ke kaumaha o kona molekala mai 1.5 miliona a 8 miliona, ʻo ia hoʻi nā ʻumi o nā manawa o nā olonā maʻamau, ʻo ia hoʻi ke kumu o kona inoa, a he hana maikaʻi loa kāna.

1. He paʻa ka ʻano a he ikaika ka inertness kemika, a ʻaʻohe hopena o nā hopena acid-base ikaika a me nā mea hoʻoheheʻe organik i kona ikaika.
2. ʻO ka nui o ke kinoea he 0.97 grams wale nō no ke kenimika cubic, a hiki iā ia ke lana ma luna o ka ʻili wai.
3. Haʻahaʻa loa ka nui o ka omo ʻana o ka wai, a ʻaʻole pono e hoʻomaloʻo ma mua o ka hoʻokumu ʻana a me ka hana ʻana.
4. Loaʻa iā ia ke kūpaʻa maikaʻi loa i ka wā ʻelemakule a me ke kūpaʻa UV. Ma hope o 1500 mau hola o ka hōʻike ʻana i ka lā, ʻoi aku ka kiʻekiʻe o ka paʻa ʻana o ka ikaika o ka fiber i ka 80%.
5. He hopena pale maikaʻi loa ia ma ka radiation a hiki ke hoʻohana ʻia ma ke ʻano he pā pale no nā mea kanu mana nukelea.
6. Ke kūpaʻa haʻahaʻa o ka mahana, loaʻa nō iā ia ka ductility i ka mahana helium wai (-269 ℃), ʻoiai nā olonā aramid e nalowale ana i ko lākou pono pale kaua ma -30 ℃; Hiki iā ia ke mālama i ka ikaika hopena maikaʻi loa i ka naikokene wai (-195 ℃), kahi ʻano i loaʻa ʻole i nā plastics ʻē aʻe, a no laila hiki ke hoʻohana ʻia ma ke ʻano he mau ʻāpana kūpaʻa haʻahaʻa i ka ʻoihana nukelea.
7. ʻO ke kūpaʻa ʻana i ke komo ʻana, ke kūpaʻa kūlou ʻana, a me ka hana luhi tensile o nā olonā polyethylene kaumaha molekala kiʻekiʻe loa ka mea ikaika loa i waena o nā olonā hana kiʻekiʻe e kū nei, me ke kūpaʻa hopena koʻikoʻi a me ka paʻakikī ʻoki. He paʻakikī ke ʻoki me ka ʻokiʻoki kahi olonā polyethylene kaumaha molekala kiʻekiʻe loa he hapaha wale nō ka mānoanoa o ka lauoho. Pono e ʻoki ʻia ka lole i hana ʻia me ka hoʻohana ʻana i kahi mīkini kūikawā.
8. Loaʻa iā UHMWPE ka hana insulation uila maikaʻi loa.
9. He maʻemaʻe a ʻaʻohe ʻawahia, hiki ke hoʻohana ʻia no ka hoʻopili ʻana me ka meaʻai a me nā lāʻau lapaʻau. Ke hoʻohālikelike ʻia me nā plastics ʻenekinia ʻē aʻe, ʻo nā fibers polyethylene kaumaha molekala kiʻekiʻe loa he mau hemahema e like me ke kūpaʻa wela haʻahaʻa, ka paʻakikī, a me ka paʻakikī, akā hiki ke hoʻomaikaʻi ʻia ma o nā ʻano hana e like me ka hoʻopiha a me ke keʻa ʻana; Mai ka manaʻo o ke kūpaʻa wela, ʻo ke kiko heheʻe o UHMWPE (136 ℃) ua like ia me ka polyethylene maʻamau, akā ma muli o kona kaumaha molekala nui a me ka viscosity heheʻe kiʻekiʻe, he paʻakikī ke hana.
