Polyethylene ea boima bo phahameng ba limolek'hule (UHMWPE, UHMW) ke karoloana ea thermoplastic polyethylene.
E boetse e tsejoa e le high-modulus polyethylene, (HMPE), e na le liketane tse telele ka ho fetisisa, tse nang le boima ba molek'hule hangata li pakeng tsa 3.5 le 7.5 limilione tse amu.The ketane e telele e sebeletsa ho fetisetsa mojaro ka katleho ho mokokotlo oa polymer ka ho matlafatsa likamano tsa intermolecular.Sena se fella ka thepa e thata haholo, e nang le tšusumetso e matla ho feta leha e le efe ea thermoplastic e entsoeng hajoale.
UHMWPE ha e nkhe, ha e latsoehe, ebile ha e chefo.E na le litšoaneleho tsohle tsa polyethylene ea boleng bo phahameng (HDPE) e nang le litšobotsi tse ekelitsoeng tsa ho hanana le li-acid tse ngata le alkalis, hammoho le litlhare tse ngata tsa manyolo.E hanyetsana haholo le lik'hemik'hale tse senyang ntle le li-oxidising acid;e na le ho monya mongobo o tlase haholo le coefficient e tlase haholo ea likhohlano;ke ho itlotsa ka bouena (sheba ho tlotsa moeli);'me e hanyetsana haholo le abrasion, ka mefuta e meng e hanyetsana le ho tsuba ka makhetlo a 15 ho feta carbon steel.Motsoako oa eona oa ho ferekanngoa o tlase haholo ho feta oa nylon le acetal 'me o bapisoa le oa polytetrafluoroethylene (PTFE, polymer), empa UHMWPE e na le khanyetso e ntle ea abrasion ho feta PTFE.
