Abstract

Tuyau et/ou raccord en matière thermoplastique extrudée ou injectée destiné aux canalisations transportant des fluides chauds ou froids, comprenant au moins trois couches dont la couche centrale est renforcée par des fibres minérales éventuellement combinées à d'autres charges, caractérisé en ce que la couche centrale comprend dans la matrice thermoplastique des additifs ou un mélange d'additifs antioxydants pouvant migrer dans les couches avoisinantes, dont la teneur est supérieure à celle des couches avoisinantes, et dont au moins 50%, de préférence 75% est constitué d'une molécule de poids moléculaire inférieur à 740g/mole, de manière à constituer un « réservoir » permettant de compenser les pertes d'additifs antioxydants enregistrées dans le temps.
