On request, OKW Gehäusesysteme GmbH can also offer its standard cases in antimicrobial plastic. Unlike antibacterial media, OKW use an antimicrobial batch which acts not only against bacteria but also against other harmful agents. These include viruses (e.g. HIV, influenza), fungi (e.g. Aspergillus Niger) and various algae.
The compound used for this consists of a standard ABS material and a sufficient admixture of the ROWACARE SAN X 10 AM batch. This additive contains so-called sterions, in which the active substance is permanently anchored in an inert carrier material and allows the controlled release of high-activity ions. These ions attack the metabolic systems of the microbes that they can no longer breed, and then die out. The material-specific properties remain practically unchanged. This means that the product surface of the new material mixture has a permanent antimicrobial effect. The standard JIS Z 2801 serves as a test for antimicrobial activity and effectiveness. The identified germs and in particular their quantity must be reduced by >2 log10 levels within a defined time frame. Depending on requirements, the concentration of the additives can be increased. Good results can be achieved with an admixture of approx. 2% of the ROWACARE batch, i.e. there is a reduction of germs >99.9% realized after 5 – 6 hours.
Besides use in the medical sector, the antimicrobial materials and products are also ideal for equipment and cases that are touched and used by different persons. This serves as a natural prophylaxis, as protection against bacteria, viruses and fungi, and is good for our most important asset, our health.
