EPDM rubber compounds.

Five EPDM compounds for potable water applications have been developed by the company. The 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 said to be rigorous and took some time, according to the company. The development process to produce these compounds is said to have taken considerable time and investment. Few rubber compounders are said to have attained this classification to ANSI/NSF Standard 61, according to the company. This classification is said to save customers a great deal of time and expense, saving manufacturers who must also be certified time and money due to the simplified approval process from using these compounds. The company also offers four polyisoprene compounds suitable for use requiring exposure to cold potable water in pipes and related products. (Preferred Rubber Compounding)
