Title (EN) POLYOLEFIN COMPOSITION FOR WATER PIPES WITH GOOD RESISTANCE TO CHLORINE DIOXIDE AND LOW MIGRATION
(FR) COMPOSITION DE POLYOLÉFINE POUR DES CONDUITES D'EAU AYANT UNE BONNE RÉSISTANCE AU DIOXYDE DE CHLORE ET UNE FAIBLE MIGRATION
Abstract:
(EN) The present invention relates to a polyolefin composition with good resistance to degradation caused by chlorine dioxide-containing water and at the same time showing low migration of the used additives and its decomposition products, especially phenols, out of the composition. The present invention is also directed to a pipe made of such a polyolefin composition. The present invention further relates to the use of the polyolefin composition for the production of a pipe and to the use of a combination of particular types of antioxidants for increasing the resistance of a polyolefin composition against degradation caused by contact with chlorine dioxide-containing water and for maintaining at the same time a low migration of the used additives and its decomposition products, especially phenols, out of the polyolefin composition.
(FR) La présente invention concerne une composition de polyoléfine ayant une bonne résistance à la dégradation causée par de l'eau contenant du dioxyde de chlore et présentant concomitamment une faible migration des additifs utilisés et de leurs produits de décomposition, en particulier des phénols, depuis la composition. La présente invention concerne en outre une conduite constituée d'une telle composition de polyoléfine. La présente invention concerne en outre l'utilisation de la composition de polyoléfine pour la production d'une conduite et l'utilisation d'une combinaison de types particuliers d'antioxydants pour augmenter la résistance d'une composition de polyoléfine à la dégradation causée par le contact avec de l'eau contenant du dioxyde de chlore et pour maintenir simultanément une faible migration des additifs utilisés et de leurs produits de décomposition, en particulier des phénols, depuis la composition de polyoléfine.
