Title (EN) POLYOLEFIN COMPOSITION FOR WATER PIPES WITH INCREASED RESISTANCE TO CHLORINE DIOXIDE
(FR) COMPOSITION DE POLYOLÉFINE POUR CANALISATIONS D'EAU AYANT UNE RÉSISTANCE ACCRUE AU DIOXYDE DE CHLORE
Abstract:
(EN) The present invention relates to a polyolefin composition with increased resistance to degradation caused by ClO2-containing water and 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 the polyolefin composition against degradation caused by contact with ClO2-containing water.
(FR) La présente invention porte sur une composition de polyoléfine ayant une résistance accrue à la dégradation provoquée par de l'eau contenant ClO2 et sur une canalisation constituée d'une telle composition de polyoléfine. La présente invention porte en outre sur l'utilisation de la composition de polyoléfine pour la production d'une canalisation et sur l'utilisation d'une association de types particuliers d'antioxydants pour l'augmentation de la résistance de la composition de polyoléfine vis-à-vis de la dégradation provoquée par le contact avec de l'eau contenant ClO2.
