POLYOLEFIN COMPOSITION FOR WATER PIPES WITH GOOD RESISTANCE TO CHLORINE DIOXIDE AND LOW MIGRATION

摘要

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.
