Ultra-high-molecular-weight polyethylene (UHMWPE, UHMW) is a subset of the thermoplastic polyethylene. Also known as high-modulus polyethylene, (HMPE), it has extremely long chains, with a molecular mass usually between 3.5 and 7.5 million amu. The longer chain serves to transfer load more effectively to the polymer backbone by strengthening intermolecular interactions. This results in a very tough material, with the highest impact strength of any thermoplastic presently made.

  • El polietileno de ultra alto peso molecular es un polímero de la familia de los polímeros olefínicos conformado por unidades repetitivas de etileno. Se le suele designar como UHMWPE (por sus siglas en inglés, Ultra-high-molecular-weight polyethylene) o HMPE (high-modulus polyethylene).​ El HMPE tiene cadenas extremadamente largas, que cuentan con una masa molecular que ronda entre 3.5 y 7.5 millones de dalton.​ Lo que hace que el HMPE sea un material muy resistente, teniendo la mayor resistencia al impacto de cualquier termoplástico fabricado.​ (es)
  • Le polyéthylène de masse molaire très élevée (UHMPE) est un polyéthylène haute densité (PE-HD) caractérisé par une excellente tenue à l'abrasion. En raison de sa très forte masse molaire, ce polyéthylène linéaire présente un indice de fluidité très faible, sa mise en forme est donc difficile. Des fibres de module très élevé peuvent être obtenues après étirage. (fr)
  • 超高分子量ポリエチレン(ちょうこうぶんしりょうぽりえちれん、Ultra High Molecular Weight Polyethylene-UHPEまたはUHMWPE)は、通常2~30万の分子量を100~700万まで高めたポリエチレン。熱可塑性樹脂に分類される合成樹脂であり、スーパーエンジニアリングプラスチックのひとつとみなされている。 ダイニーマ(Dyneema、コーニンクレッカDSM、東洋紡がライセンス生産)、スペクトラ(Spectra、ハネウェル)などの商品名でも呼ばれる。 (ja)
  • 초고분자량 폴리에틸렌(ultrahigh molecular weight polyethylene, UHMWPE)은 열가소성 폴리에틸렌의 일종이다. (ko)
  • UHMW (Ultra high molecular weight polyethylene) é a sigla em inglês para Polietileno de Ultra Alto Peso Molecular. O peso molecular extremamente elevado proporciona a esse plástico de engenharia, além de excelentes propriedades mecânicas, uma viscosidade tão alta no estado fundido que o índice de fluidez (190oC / 21,6kg) aproxima-se de zero. Destacam-se como principais qualidades a alta resistência ao desgaste por abrasão, a alta resistência ao impacto e o baixo coeficiente de atrito. (pt)
  • Сверхвысокомолекуля́рный полиэтилéн (СВМПЭ, англ. Ultra-high molecular weight polyethylene, UHMW PE) — термопластичный полимер, конструкционный материал, пригодный для работы в экстремальных условиях эксплуатации. Синонимы: * полиэтилен с высоким модулем упругости (англ. High modulus polyethylene, HM PE); * полиэтилен с высокими эксплуатационными характеристиками (англ. High performance polyethylene, HP PE). Сверхвысокая масса молекул определяет уникальные свойства СВМПЭ, отличные от других разновидностей полиэтилена. (ru)

  • Il polietilene ad altissimo peso molecolare (in inglese Ultra High Molecular Weight Poly-Ethylene) è un polimero specialistico, non fluido, lavorato con tecniche simili a quelle dei metalli; ha una massa atomica di 3-6 MDa.Filato al 5% in naftalina o decalina dà una fibra, chiamata Dyneema con una cristallinità dell'85% e densità di 0,97 g/cm3. Questa "super-fibra" è utilizzata per applicazioni speciali quali indumenti anti-proiettile, vele, cordami; risulta essere 2 volte più resistente del kevlar e 15 volte più dell'acciaio a parità di peso. Rappresenta il materiale più leggero e resistente in commercio.Seppur sia un polimero lineare, il suo grado di cristallinità non è elevato (45-60%), e può essere anche inferiore a quello dell'LDPE (50-60%). Il motivo sta nel fatto che l'UHMWPE allo s (it)
