Title (EN) ABRASION RESISTANT FLEXIBLE COMPOSITES AND MULTILAYER PIPE LINERS FOR CURED-IN-PLACE PIPE
(FR) REVÊTEMENTS DE TUYAU MULTICOUCHES ET COMPOSITES SOUPLES RÉSISTANT À L'ABRASION POUR TUYAU DURCI EN PLACE
Abstract:
(EN) Embodiments of the present disclosure include composites and flexible multilayer pipe liners comprising a fibrous layer; and a polyolefin backing layer comprising a blend of: (a) an ultra-high molecular weight ethylene-based polymer having an intrinsic viscosity from 5 to 50 deciliters/gram, (b) a polyethylene resin comprising a first molecular weight ethylene-based polymer component and a second molecular weight ethylene-based polymer component, wherein the polyethylene resin has a density from 0.930 to 0.960 g/cc; (c) a thermoplastic polyolefin elastomer having a density of from 0.850 to 0.910 g/cc; and (d) optionally, a fluoropolymer.
(FR) Certains modes de réalisation de la présente invention concernent des composites et des revêtements de tuyau multicouches souples comprenant une couche fibreuse ; et une couche dorsale de polyoléfine comprenant un mélange des constituants suivants : (a) un polymère à base d'éthylène à ultra haut poids moléculaire présentant une viscosité intrinsèque de 5 à 50 décilitres/gramme ; (b) une résine de polyéthylène comprenant un constituant polymère à base d'éthylène d'un premier poids moléculaire et un constituant polymère à base d'éthylène d'un deuxième poids moléculaire, cette résine de polyéthylène présentant une densité de 0,930 à 0,960 g/cc ; (c) un élastomère polyoléfinique thermoplastique présentant une densité de 0,850 à 0,910 g/cc ; et (d), facultativement, un polymère fluoré.
