Abstract
The present invention relates to the use of a polyolefin composition for water pipes or fittings with increased resistance to degradation caused by chlorine dioxide-containing water, particularly 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.
