ABSTRACT:
This invention relates to certain non-silicone vulcanized rubber articles that are made from at least a majority by weight of vulcanized styrene butadiene rubber that include silver-based compounds to provide highly desirable long-term antimicrobial characteristics within the cured rubber articles. Such articles are in either solid or blown (foam or sponge) state (or combinations of both in multilayered forms) and can be utilized in a variety of different applications. This invention encompasses the presence of non-sulfur-based curing systems and agents, such as peroxide curing, that permit vulcanization and do not irreversibly bind silver ions thereto, thereby resulting in long-term antimicrobial performance of the ultimate rubber article itself. This invention also encompasses certain non-silicone pre-vulcanized raw rubber formulations made from at least a majority by weight of styrene butadiene rubber that include silver-based components to provide highly desirable long-term antimicrobial characteristics within the ultimate cured rubber articles made therefrom.
