The most innovative aspect of the BactiBlock® additive is that purified and modified phyllosilicate clay is used as performance-enhancing carrier of the silver antimicrobial agent. This creates strong synergies between the two materials, especially in terms of efficiency and durability. Efficiency – Do more with less During the proprietary production process, ionic silver is linked to the clay surface, obtaining a uniform distribution of the active species within the additive. In addition, the silver deposited on the clay prevents platelet agglomeration, which ensures global additive dispersion. The combination of these dispersion mechanisms maximizes antimicrobial efficiency and homogenous protection of the polymer material. Durability – The longer lasting solution The silver species linked to the clay platelets are released to the surface of the protected material at a controlled rate. This ensures a more uniform and long term antimicrobial effect, compared to additives with the active species readily available in the polymer. BactiBlock® is therefore ideally suited for long term applications and although durability in most cases depends on wear and environmental conditions (temperature and humidity), the antimicrobial performance can be expected to endure for several years.

Manufacturer's Description

BactiBlock® is an antimicrobial additive for polymer-based raw materials. The proprietary and patent-pending BactiBlock® technology is based on silver-functionalized clay that creates a naturally sourced and highly efficient antimicrobial product. The additive prevents the growth of bacteria, mold, fungus and other microorganisms, which also makes BactiBlock® a powerful tool against odors and stains.
