Advanced Silane-based Biosafe Antimicrobial Compounds
Biosafe Inc.'s polymeric solid antimicrobial Biosafe HM-4100 is a nontoxic, environmentally sustainable silane-based cationic quaternary ammonium salt not previously used in plastics as its liquid form made it difficult to incorporate. The crystalline powder based on patented polymer technology is suitable for a wide range of thermoplastics. HM-4100 protects plastic products from staining/damage caused by bacteria, mildew, and fungi. It is thermally stable in injection molding and extrusion, will not discolor, or migrate out of the plastic and can be used with optically clear resins without compromising their optical properties. The antimicrobial functions by puncturing and rupturing cell walls, eliminating the possibility to mutate and become resistant to the antimicrobial. Biosafe Inc. has partnered with compounder RTP Co. to make the antimicrobial available in masterbatch form. Biosafe's chemistry is listed by FDA as a modifier for medical devices.
