ʻO ka fiber polyethylene kaumaha kiʻekiʻe kiʻekiʻe (UHMWPE), i ʻike ʻia ʻo ka fiber PE ikaika kiʻekiʻe, ʻo ia kekahi o nā fibers ʻenehana kiʻekiʻe ʻekolu o ka honua i kēia lā (carbon fiber, aramid fiber, a me ultra-high molecular weight polyethylene fiber), a ʻo ia hoʻi ka fiber paʻakikī loa ma ka honua.He māmā ia e like me ka pepa a ʻoi aku ka paʻakikī e like me ke kila, me ka ikaika he 15 mau manawa ma mua o ke kila, a ʻelua hoʻi ko ka fiber carbon a me ka aramid 1414 (Kevlar fiber).ʻO ia ka mea nui no ka hana ʻana i nā lole pale pale.
ʻO kona kaumaha molekala mai ka 1.5 miliona a hiki i ka 8 miliona, ʻo ia ka nui o nā manawa o nā fibers maʻamau, ʻo ia hoʻi ke kumu o kona inoa, a he hana maikaʻi loa ia.

1. ʻOi aku ka paʻa a me ka inertness kemika ikaika, a ʻaʻohe hopena o ka ʻakika-base ikaika a me nā solvents organik i kona ikaika.
2. He 0.97 grama wale nō ka mānoanoa o kēlā me kēia kenimika cubic, a hiki iā ia ke lana ma luna o ka wai.
3. He haʻahaʻa loa ka nui o ka wai, a ʻaʻole pono e maloʻo ma mua o ka hana ʻana a me ka hana ʻana.
4. Loaʻa iā ia ka maikaʻi o ka wā kahiko a me ka pale UV.Ma hope o 1500 mau hola o ka ʻike ʻana i ka lā, ʻoi aku ka kiʻekiʻe o ka ikaika o ka fiber e like me 80%.
5. He hopena pale maikaʻi loa ia i ka radiation a hiki ke hoʻohana ʻia ma ke ʻano he pale pale no nā mea kanu nuklea.
6. Haʻahaʻa wela kū'ē, ka mea mau ductility i ka wai helium wela (-269 ℃), oiai aramid fibers nalowale ko lakou bulletproof pono ma -30 ℃;Hiki iā ia ke mālama i ka ikaika hopena maikaʻi loa i loko o ka nitrogen wai (-195 ℃), kahi ʻano i loaʻa ʻole i nā plastics ʻē aʻe, a no laila hiki ke hoʻohana ʻia e like me nā ʻāpana haʻahaʻa haʻahaʻa i ka ʻoihana nuklea.
7. ʻO ke kūpaʻa ʻaʻahu, ke kūlou ʻana, a me ka hana luhi ʻana o nā fibers polyethylene kaumaha ultra-high molecular weights ʻoi aku ka ikaika ma waena o nā fibers hana kiʻekiʻe e kū nei, me ke kūpaʻa hopena maikaʻi a me ka ʻoki ʻoki.ʻO kahi polyethylene fiber ultra-high molecular weight he hapaha wale nō ka mānoanoa o ka lauoho paʻakikī ke ʻoki ʻia me ka ʻoki.Pono e ʻoki ʻia ka textile i hana ʻia me ka mīkini kūikawā.
8. UHMWPE loaʻa i ka maikaʻi o ka hana hoʻokaʻawale uila.
9. ʻO ka maʻemaʻe a me ka meaʻawaʻawaʻole, hiki ke hoʻohanaʻia no ka pilina me ka meaʻai a me nā lāʻau lapaʻau.Ke hoʻohālikelike ʻia me nā plastics ʻenekinia ʻē aʻe, he nui nā hemahema o nā fibers polyethylene kaumaha ultra-kiʻekiʻe e like me ka haʻahaʻa haʻahaʻa wela, ʻoʻoleʻa, a me ka paʻakikī, akā hiki ke hoʻomaikaʻi ʻia ma o nā ʻano e like me ka hoʻopiha a me ka hoʻopili ʻana;Mai ka hiʻohiʻona o ke kūpaʻa wela, ʻo ka helu heheʻe o UHMWPE (136 ℃) maʻamau e like me ka polyethylene maʻamau, akā ma muli o kona kaumaha nui mole a me ka viscosity hoʻoheheʻe kiʻekiʻe, paʻakikī ke hana.
