18| PLASTICS ENGINEERING | OCTOBER 2011| www.4spe.orgChlorine chemistry iscomplex. Under cer-tain common condi-tions, chlorinatedcompounds can react with poly-ethylene pipes, causing prematurefailures (bursts/leaks). It is impor-tant to understand this degrada-tion mechanism in order to pre-vent premature pipe failure.Recently, a specific additive sys-tem, when incorporated into poly-ethylene pipe resin, was demon-strated to significantly improve thepipe's resistance to degradationcaused by chlorine exposure.Jerry Eng,* Thomas Sassi,* Thomas Steele,* and Giacomo Vitarelli***Cytec Industries, Stamford, Connecticut, USA**Cytec Industries, Milano, ItalyPhoto by Nicole-Koehler
