Preferred Rubber Compounding Corp. has announced five new EPDM compounds for potable water applications. The new rubber compounds were recently classified by Underwriters' Laboratories to the National Sanitation Foundation (NSF) Standard 61, Drinking Water System Components--Health Effects. Designed for minimal extraction of ingredients in potable water applications, the compounds will not leach out when used in the manufacture of seals and gaskets for pipes and other conveyors of water. "The testing by Underwriters' Laboratories to the Standard was rigorous and took some time, but we're very pleased with the results," said Bruce Corson, Director of Business Development at Preferred Rubber Compounding. "The development process to produce these compounds took considerable time and investment. Few rubber compounders have attained this classification to ANSI/NSF Standard 61. We're proud and eager to offer these new compounds to manufacturers."
