Hoʻolauna UHMWPE:
ʻO ka polyethylene kaumaha molekala kiʻekiʻe loa (UHMW-PE) e pili ana i ka polyethylene linear me ka awelika o ke kaumaha molekala ma mua o 1.5 miliona. Ma muli o kona kaumaha molekala kiʻekiʻe loa (ʻo ka polyethylene maʻamau he 20,000 a 300,000, loaʻa iā UHMW-PE ka hana piha i hoʻohālikelike ʻia me ka polyethylene maʻamau a me nā plastics ʻenekinia ʻē aʻe:
1) Ke kūpaʻa ʻana i ke kapa komo kiʻekiʻe loa, 4 mau manawa ʻoi aku ka kiʻekiʻe ma mua o ka nylon 66 a me ka PTFE, 6 mau manawa ʻoi aku ka kiʻekiʻe ma mua o ke kila kalapona, ʻo ia ka mea maikaʻi loa ma waena o nā resins synthetic āpau i kēia manawa.
2) He kiʻekiʻe loa ka ikaika o ka hopena, ʻo ia hoʻi he 2 manawa o ka polycarbonate a me 5 manawa o ka ABS, a hiki ke mālama i ka paʻakikī kiʻekiʻe ma ka mahana o ka naikokene wai (-196 ℃).
3) ʻO ka waiwai lubrication ponoʻī maikaʻi, ʻo kona waiwai lubrication ponoʻī ua like ia me ko PTFE, a ʻo ke koina friction he 0.07-0.11 wale nō; he 1/4-1/3 wale nō ia o ke koina friction o ke kila.
4) ʻO ke kumukūʻai omo ikehu haʻalulu ka mea kiʻekiʻe loa ma waena o nā plastics āpau, a maikaʻi loa ka hopena hōʻemi walaʻau.
5) Loaʻa iā ia ke kūpaʻa kemika kiʻekiʻe a hiki ke kū'ē i nā ʻano media corrosive like ʻole a me nā media organik i loko o kahi mahana a me ka pae hoʻohuihui.
6) Ka hiki ke pale aku i ka hoʻopili ʻana, ʻo ka lua wale nō i ka "Plastic King" PTFE.
7) Hoʻomaʻemaʻe loa a ʻaʻohe mea ʻawahia, hiki ke hoʻohana ʻia i ka launa pū ʻana me ka meaʻai a me nā lāʻau lapaʻau.
8) ʻO ka nui ka mea liʻiliʻi loa ma waena o nā plastics ʻenekinia āpau, 56% māmā ma mua o ka PTFE a me 22% māmā ma mua o ka polycarbonate; ʻo ka nui he 1/8 o ke kila, a pēlā aku.
Ma muli o ka hana piha maikaʻi loa i luna nei, ua kapa ʻia ʻo UHMW-PE ʻo "plastic kupaianaha" e nā ʻāina ʻEulopa a me ʻAmelika a ua waiwai nui ʻia a hoʻohana nui ʻia i nā ʻoihana he nui.
