Several ingredients in rubber parts are an excellent carbon and energy source for  microorganisms. Additionally, rubber parts are commonly used in microbial rich environments, such as medical devises, food processing plants, or water lines, all of which are warm, moist and difficult to clean. These aspects present the ideal scenario for biofilm formation. Biofilm formation not only results in the premature degradation of the rubber parts, but can also have negative consequences for the end user. This paper contrasts and summarizes two applications in need for a solution against biofilm formation: silicone stoppers in intravenous (IV) connectors and door gaskets for washing machines. Microbial contamination of medical devices has been linked to nosocomial infections which can be tremendously detrimental to the patients’ recovery and cost millions of dollars to our health care system. On the other hand, biofilm formation on the door gasket of washing machines generates mal odor and stains the clothes. This has resulted in customer dissatisfaction and in millions of dollars in litigation for the appliance industry. We have developed a safe and durable technology, approved by US and EU regulatory agencies, with proven efficacy against fungi and bacteria both in the laboratory and in simulated use studies.
