This group of masterbatches with trade name NovinCide® is supplied in three different categories: anti-bacterial, anti-fungal and anti-algae. They contain novel biocide additives based on metal oxide nanoparticles, and produced using a specific technique that allows full dispersion with no agglomeration and change in particle size. Thus, they are fully incorporated in the masterbatch, providing excellent anti-microbial properties. These masterbatches are completely natural in color and do not add any color effect to the product, thus preserving the natural color as well as mechanical properties of the product. Bacteria elimination in incorporated antimicrobial masterbatch products is done via various methods which lead to give them the ability to perform well in different environmental conditions such as dark, dry, and high humidity.
