New Additive Technology to Improve the Chlorine Resistance of Potable HDPE Pipe
A new high performance stabilizer solution has been developed for use in HDPE, especially for pipe where exposure to chlorine is anticipated. Chlorine-based disinfectants are known to be extremely effective in eliminating waterborne pathogens in potable water systems but can also contribute to pipe deterioration. Chlorine disinfectants also interfere with stabilizer additive packages which provide pipe longevity. This new plastic additive technology enables HDPE pipes to be used in contact with chlorinated water estimated to have service life-time of more than 50 years. The new technology meets current drinking water regulations and reduces the migration of non-intentionally added substances, NIAS, including Arvin substances.
