Abstract

This disclosure relates generally to molded rubber articles such as the type used in water contact applications. More particularly, this disclosure is directed to molded rubber articles containing antimicrobial agents that control biofilm growth on the surface of the molded article. The molded rubber article is comprised of curable rubber compounds and a combination of both inorganic silver-containing antimicrobial agents and organic antimicrobial agents. An exemplary molded rubber article comprises ethylene propylene diene monomer rubber, silver-containing ion exchange antimicrobial agent, and an organic antifungal agent such as zinc pyrithione.
