The UHMWPE mbale utenga Ziegler mtundu mkulu-mwachangu chothandizira otsika-anzanu kaphatikizidwe njira ndipo amalamulidwa pamwamba 1.5 kwa 3 miliyoni monga pakufunika.Poganizira kuwonongeka kwa matenthedwe a mamolekyu pa processing, mkulu-kachulukidwe polyethylene ndi mamasukidwe akayendedwe pafupifupi maselo oposa 1.7 miliyoni akhoza kukonzedwa mu mankhwala osiyanasiyana kuti ntchito kwambiri apamwamba.

1. Kukana kuvala kwakukulu: mbale ya UHMWPE ili ndi kukana kovala bwino pakati pa mapulasitiki onse a uinjiniya wamakono ndipo ndi yochititsa chidwi kwambiri.Mamolekyu akakhala okwera, m'pamenenso zinthuzo sizimva kuvala, kuposa zinthu zambiri zachitsulo (monga chitsulo cha carbon, chitsulo chosapanga dzimbiri, mkuwa, ndi zina zotero).Mwachitsanzo, mapaipi a UHMW-PE amakhala ndi moyo wautumiki wa nthawi 4-6 kuposa mipope yachitsulo pansi pa dzimbiri lamphamvu komanso kuvala kwambiri, ndikuwonjezera kufalikira kwa 20%.Ikuwonetseratu kukula kwa "kupulumutsa mphamvu, kuteteza chilengedwe, chuma ndi kuchita bwino kwambiri".
2. Kulimbana ndi dzimbiri: Sizidzimbirira mu sopo ndipo zitha kugwiritsidwa ntchito mu hydrochloric acid yokhazikika pa 80°C.Imakhala ndi ntchito yokhazikika mu 75% yokhazikika ya sulfuric acid ndi 20% nitric acid.Ndiwokhazikika kumadzi am'nyanja ndi zotsukira zamadzimadzi.
3. Coefficient yotsika kwambiri ya kukangana: Coefficient of static friction ndi 0.07, ndipo imakhala ndi zinthu zabwino zodzipangira zokha.Ndibwino kunyamula, bushing, sliding block ndi lining material.Kugwiritsa ntchito mbale ya UHMWPE ngati gawo losagwirizana la zida sikungowonjezera moyo wosamva, komanso kulandira mphamvu zopulumutsa mphamvu.
4. Kukana kwamphamvu: Kukana kwamphamvu kumakhala koyamba pakati pa mapulasitiki.Kaya ndi mphamvu yakunja yamphamvu kapena kusinthasintha kwapakati, kumakhala kovuta kusweka.Mphamvu yake imaposa 10 kuposa ya nayiloni 66, nthawi 20 ya polyvinyl chloride, ndi kuchulukitsa ka 8 kuposa polytetrafluoroethylene.Makamaka m'malo otsika kutentha, mphamvu zake zimafika pamtengo wapamwamba, ndipo kusinthasintha kwake kungapereke machitidwe otetezeka kwambiri oyendetsa, chitsimikizo chodalirika.
