Al2O3 • 2SiO2 • 2H2O Nanoparticle /Nanopowder CAS Number : 1332-58-7




The most innovative aspect of the O2Block® additive is that purified and modified layered clay is used as a performance-enhancing carrier of the oxygen-scavenging iron. This creates strong synergies between the two materials, especially in terms of versatility and efficiency. Versatility The foundation of the O2Block® technology comes from our original expertise with surface modification and dispersion engineered clay additives in a wide range of polymer systems. The unique chemical and physical treatment of the engineered O2Block® range allows us to design an additive that can be dispersed directly in almost any polymer system. The material is immediately active after being added to the packaging system. These characteristics present significant advantages over systems where sachet solutions or additional activation equipment is required. Efficiency and speed During the proprietary production process, active iron is linked to the clay surface, obtaining a uniform distribution of the active element within the additive. In addition, the iron deposited on the clay prevents platelet agglomeration, which combined with unique surface modification ensures global additive dispersion. Compared to other commercial systems, the effective dispersion maximizes the access to the active iron, which ensures minimum reaction time and a uniform protection of the packaged goods.

Versatility Oxygen Barrier

Manufacturer's Description

O2Block® by NanoBioMatters is an oxygen scavenging additive for polymer-based materials. The proprietary and patent-pending O2Block® technology is based on surface-modified phyllosilicate clay that is functionalized with active iron to create a naturally sourced and highly efficient oxygen scavenging product for maximum shelf life in barrier packaging.
