Ulusi wolemera kwambiri wa polyethylene fiber (UHMWPE), womwe umadziwikanso kuti PE wapamwamba kwambiri, ndi umodzi mwazitsulo zitatu zamakono padziko lapansi masiku ano (carbon fiber, aramid fiber, ndi ultra-high molecular weight polyethylene fiber), ndi ndi ulusi wovuta kwambiri padziko lapansi.Ndi yopepuka ngati pepala komanso yolimba ngati chitsulo, yokhala ndi mphamvu 15 kuposa yachitsulo, komanso kuwirikiza kawiri ya carbon fiber ndi aramid 1414 (Kevlar fiber).Pakalipano ndizomwe zimagwiritsidwa ntchito popanga zovala za bulletproof.
Kulemera kwa mamolekyu ake kumayambira pa 1.5 miliyoni kufika pa 8 miliyoni, kuwirikiza kambirimbiri kuposa ulusi wamba, womwenso ndi kumene dzina lake linachokera, ndipo amachita bwino kwambiri.

1. Mapangidwewo ndi owundana ndipo ali ndi mphamvu zogwiritsira ntchito mankhwala, ndipo njira zogwiritsira ntchito asidi-base ndi zosungunulira za organic sizikhudza mphamvu zake.
2. Kachulukidwe kake ndi 0,97 magalamu pa kiyubiki centimita imodzi, ndipo imatha kuyandama pamadzi.
3. Mayamwidwe amadzi ndi otsika kwambiri, ndipo nthawi zambiri sikofunikira kuumitsa musanapange ndi kukonza.
4. Ili ndi nyengo yabwino yokana kukalamba komanso kukana kwa UV.Pambuyo pa maola 1500 akukhala padzuwa, mphamvu yosungira mphamvu ya fiber ikadali yokwera mpaka 80%.
5. Imakhala ndi chitetezo chabwino kwambiri pama radiation ndipo ingagwiritsidwe ntchito ngati mbale yotchinjiriza pazomera zamagetsi za nyukiliya.
6. Kutsika kwa kutentha kukana, kumakhalabe ndi ductility pa kutentha kwa madzi a helium (-269 ℃), pamene ulusi wa aramid umataya mphamvu zawo zoteteza zipolopolo pa -30 ℃;Itha kukhalanso ndi mphamvu zogwira mtima kwambiri mu nayitrogeni wamadzimadzi (-195 ℃), mawonekedwe omwe mapulasitiki ena alibe, motero amatha kugwiritsidwa ntchito ngati zigawo zosagwirizana ndi kutentha kochepa pamakampani anyukiliya.
7. Kukana kuvala, kukana kupindika, komanso kutopa kwamphamvu kwa ulusi wa polyethylene wochuluka kwambiri wa molekyulu ndi wamphamvu kwambiri pakati pa ulusi wochita bwino kwambiri, wokhala ndi kukana kwambiri komanso kulimba mtima.Ulusi wochuluka kwambiri wa molekyulu wolemera kwambiri wa polyethylene womwe ndi kotala la makulidwe a tsitsi ndizovuta kudula ndi lumo.Nsalu zokonzedwa ziyenera kudulidwa pogwiritsa ntchito makina apadera.
8. UHMWPE imakhalanso ndi ntchito yabwino kwambiri yotchinjiriza magetsi.
9. Zaukhondo komanso zopanda poizoni, zitha kugwiritsidwa ntchito pokhudzana ndi chakudya ndi mankhwala.Poyerekeza ndi mapulasitiki ena a uinjiniya, ulusi wa polyethylene wapamwamba kwambiri wa molekyulu amakhala ndi zofooka monga kukana kutentha pang'ono, kuuma, ndi kuuma, koma zimatha kupitilizidwa kudzera m'njira monga kudzaza ndi kulumikiza;Kutengera kukana kutentha, malo osungunuka a UHMWPE (136 ℃) nthawi zambiri amakhala ofanana ndi polyethylene wamba, koma chifukwa cha kulemera kwake kwa mamolekyulu komanso kukhuthala kwakukulu, zimakhala zovuta kukonza.
