Title (EN) PREMIUM PIPE RESINS
(FR) RESINES POUR TUYAUX DE QUALITE SUPERIEURE
Abstract:
(EN) The invention relates to the production of high performance conduits. The invention includes the high performance conduits, the polyethylene resin used to make them, and the process for producing the resin which produces a resin with properties which are required, in accordance with the invention to yield the performance characteristics of the resin in conduits. The resin used in accordance with the invention exhibits a bimodal molecular weight distribution or broad molecular weight distribution and is of high molecular weight.
(FR) L'invention concerne la production de conduits à haute performance. L'invention se rapporte à des conduits à haute performance, à la résine polyéthylène utilisée pour les fabriquer et au procédé de production de résine, qui consiste à produire une résine présentant les propriétés requises, en fonction de l'invention, de sorte que les caractéristiques fonctionnelles de la résine dans les conduits soit obtenues. La résine utilisée selon le procédé de l'invention présente une répartition des poids moléculaires bimodale ou large et présente un poids moléculaire élevé.
