When designing a medical device, selecting a material that will last and perform well under harsh conditions has never been tougher. Currently, concerns over healthcare-associated infections (HAIs) have led many medical facilities to respond by disinfecting equipment surfaces more frequently using harsher disinfectants. Versaflex™ HC thermoplastic elastomers can enhance ergonomics in medical devices by adding a soft touch and improved grip.
