Polyethylene yolemera kwambiri ya molekyulu (UHMW-PE) imatanthauza polyethylene yolunjika yokhala ndi kulemera kwapakati kwa molekyulu yoposa 1.5 miliyoni. Chifukwa cha kulemera kwake kwakukulu kwa molekyulu (polyethylene wamba ndi 20,000 mpaka 300,000, UHMW-PE ili ndi magwiridwe antchito osayerekezeka poyerekeza ndi polyethylene wamba ndi mapulasitiki ena auinjiniya:

1) Kukana kwambiri kutopa, kokwera kasanu kuposa nayiloni 66 ndi PTFE, kokwera kasanu ndi kamodzi kuposa chitsulo cha carbon, ndipo ndi bwino kwambiri pakati pa ma resini onse opangidwa pakadali pano.

2) Mphamvu ya kugwedezeka ndi yayikulu kwambiri, yomwe ndi yowirikiza kawiri kuposa polycarbonate ndi yowirikiza kasanu kuposa ABS, ndipo imatha kukhalabe yolimba kwambiri kutentha kwa nayitrogeni yamadzimadzi (-196 ℃).

3) Katundu wabwino wodzipaka mafuta, katundu wake wodzipaka mafuta ndi wofanana ndi wa PTFE, ndipo chiŵerengero cha kukangana ndi 0.07-0.11 chokha; ndi 1/4-1/3 yokha ya chiŵerengero cha kukangana kwa chitsulo.

4) Mphamvu yoyamwa ya shock energy ndiyo yapamwamba kwambiri kuposa mapulasitiki onse, ndipo mphamvu yochepetsera phokoso ndi yabwino kwambiri.

5) Ili ndi kukhazikika kwa mankhwala ambiri ndipo imatha kukana zinthu zosiyanasiyana zowononga komanso zinthu zachilengedwe mkati mwa kutentha kwina ndi kuchuluka kwake.

6) Mphamvu yolimbana ndi kumatira mwamphamvu, yachiwiri kwa "Plastic King" PTFE.

7) Ndi yaukhondo komanso yopanda poizoni, ingagwiritsidwe ntchito ikakhudzana ndi chakudya ndi mankhwala.

8) Kuchuluka kwake ndi kochepa kwambiri pakati pa mapulasitiki onse opanga uinjiniya, 56% yopepuka kuposa PTFE ndi 22% yopepuka kuposa polycarbonate; kuchulukira kwake ndi 1/8 ya chitsulo, ndi zina zotero.

Chifukwa cha ntchito yabwino kwambiri yomwe yatchulidwa pamwambapa, UHMW-PE imatchedwa "pulasitiki yodabwitsa" ndi mayiko aku Europe ndi America ndipo yakhala ikuyamikiridwa komanso kugwiritsidwa ntchito kwambiri m'mafakitale ambiri.
