Chroma Color Corporation offers two types of antimicrobial master batches, MicroBlok®Z and MicroBlok®S. These master batches are comprised of either Zinc Pyrithione or Silver Ion technology.
Both active ingredients are registered with the EPA and have strict guidelines on use applications.
It is important to understand the customer’s end use application to make sure it complies with EPA application guidelines for either of our MicroBlok® products.
MicroBlok® master batches can be customized in many different polymer resin systems to meet customer requirements.
MicroBlok® master batches can be produced as a natural additive master batch or incorporated into color master batches and pre-colored compounds.
MicroBlok® products are intended to impede the growth of microbes and bacteria on the product’s surface and are not intended to be a substitute for good hygiene or to prevent foodborne or infectious illnesses.
MicroBlok® products in some cases meet FDA requirement but with restrictions and specific guidelines.
Chroma Color Corporation makes no specific claims of efficacy and testing should fall to the customer to test and verify on their end product.
In the US, as well as other countries, before a material can be sold as an anti-microbial, it must be registered with the appropriate governmental authorities. The registration number must be posted on the product label.
It is the responsibility of the product producers (processors, converters, or OEMs) to investigate the regulations before manufacturing items for distribution or use in any country.
It is a federal offense to use an antimicrobial in an unapproved manner.
