Abstract

La présente invention concerne un tube multicouche en matière plastique. Dans ce tube, au moins une couche, de préférence la couche centrale (3), se compose d'une polyoléfine renforcée avec une matière minérale ou un mélange de matières minérales, la proportion de la polyoléfine dans cette couche (3) étant de 25 à 70% en poids, et cette couche est expansée jusqu'à obtention d'une densité inférieure d'au moins 10% à celle d'une couche renforcée avec une matière minérale et non expansée présentant une composition identique.
