  • Carbon Black-Containing Crosslinked Polyethylene Pipe Having Resistance To Chlorine And Hypochlorous Acid
    Publication number: 20080017268
    Abstract: Pipe or tubing of crosslinked polyethylene (“PEX”) containing less than 2% by wt. carbon black provides improved resistance to oxidizing agents such as chlorine and hypochlorous acid in water. The pipe may be further protected with a thin tubular core (inner layer) of high density polyethylene or chlorinated polyethylene. The pipe may optionally have an oxygen barrier layer, such as poly(ethylene-co-vinyl alcohol) (“EVOH”), contiguously disposed radially outward from the carbon-containing PEX layer. The pipe is suitable for potable water applications and for hot water radiant heating systems.
