Sanitized® BC A 21-72

Technical Datasheet | Supplied by Sanitized
Sanitized® BC A 21-72 by Sanitized Antimicrobial is an antimicrobial based on a natural active ingredient in the form of silver encapsulated in a patented glass ceramic material. The pure active ingredient has a strong effect against a large number of microbes such as bacteria. The additive can be used in sheets as well as in extruded and molded parts made from polycarbonate and polystyrene. Due to the high temperature resistance the additive is compatible in polymers processed at temperatures far beyond what organic active ingredients can resist. Substrates protected with Sanitized® BC A 21-72 are noted for their excellent skin tolerance and are safe for man and environment. Sanitized® BC A 21-72 is supplied in powder form. It is EPA-registered & BPR-compliant. Approved for polymers with food contact (US FDA). Recommended dosage level is 0.1-0.6% to the total weight of the material to be protected.
