O2Block barrier

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.

Surface-modified organoclay additives based on a selection of layered minerals (phillosilicates) and food contact approved surface modification systems. These products are specifically designed to create a barrier for migrants, such as oxygen, water vapour, oils.
