Polycarbonate Resin Poised to Provide Weapon Against Hospital Infection
Two grades of antimicrobial polycarbonate resin have been developed for use in the production of medical devices. Advances in antimicrobial technology now permit the use of silver-based inorganic antimicrobials in engineering thermoplastics to control the growth of gram-positive and gram-negative bacteria on the surface of medical devices. Two different grades of polycarbonate have different levels of efficacy, yet with both grades the antimicrobial additive is a component of the polycarbonate formulation. Stain testing shows that bacteria on untreated polycarbonate grow unabated while bacteria growth on the antimicrobial polycarbonate is virtually nonexistent.
