Title
(EN) BIAXIALLY ORIENTED PIPE
(FR) TUYAU À ORIENTATION BIAXIALE
Abstract
(EN)
The invention relates to a biaxially oriented pipe made of a polymer composition comprising a propylene- based polymer, wherein the propylene- based polymer comprises a random copolymer of propylene and a comonomer which is ethylene and/or an a-olefin having 4 to 10 carbon atoms, wherein the propylene-based polymer has a comonomer content of 0.5 to 3.8 wt% based on the propylene-based polymer.
(FR)
L'invention concerne un tuyau à orientation biaxiale constitué d'une composition polymère comprenant un polymère à base de propylène, le polymère à base de propylène comprenant un copolymère aléatoire de propylène et un comonomère qui est de l'éthylène et/ou une a-oléfine ayant 4 à 10 atomes de carbone, le polymère à base de propylène ayant une teneur en comonomère de 0,5 à 3,8 % en poids sur la base du polymère à base de propylène.
