Disclosed is a high density multimodal polyethylene composition that has a density of 0.935 g/cc or more, and that includes a blend of a first polyethylene component and a second polyethylene component, in which: the first polyethylene component includes a bimodal polyethylene; and the second polyethylene component includes a metallocene produced unimodal polyethylene, the composition characterized in having a low level of polyethylene having a molecular weight of less than 1,000 amu and a low level of polyethylene having a molecular weight greater than 500,000 amu.
La présente invention concerne une composition de polyéthylène multimodale à haute densité qui présente une densité supérieure ou égale à 0,935 g/cc et qui comprend un mélange d'un premier composant de polyéthylène et d'un second composant de polyéthylène. Le premier composant de polyéthylène comprend un polyéthylène bimodal et le second composant de polyéthylène comprend un polyéthylène unimodal métallocène. La composition selon cette invention est caractérisée en ce qu'elle présente une faible teneur en polyéthylène présentant un poids moléculaire inférieur à 1000 uma et une faible teneur en polyéthylène présentant un poids moléculaire supérieur à 500000 uma.
