| Microorganisms such as fungi and bacteria are present in all environments, although they are invisible to the naked eye. The reproduction and growth of bacteria, fungi, mildew and molds happen rapidly on plastic surfaces. CESA-antimicro masterbatches inhibit the growth of these microorganisms, helping to prevent unpleasant odors, discoloration, and surface degradation of plastic parts. |

Typical applications for antimicrobials include fibers and textiles used in athletic gear and household furnishings, kitchenware and bathroom products, automotive steering wheels and interior parts, pharmaceutical and medical products, and a spectrum of other plastic applications requiring a high standard of hygiene.
There are two major types of antimicrobials, both of which are represented in the CESA-antimicro product line. Organic antimicrobials consist of substances that migrate within the polymer matrix, spreading over the surface of the materials where their antimicrobial action has effect. Organic antimicrobials are effective at low concentrations, offering a favorable cost/performance ratio in polymers that are processed at temperatures not exceeding 250°C (482°F).
Inorganic antimicrobials incorporate substances containing silver in ionic form, bound to inorganic compounds that regulate the diffusion of ions within the polymer mass. The silver ion is the active ingredient that interacts with bacteria. nontoxic, non-corrosive and flameproof, inorganic antimicrobials have no negative impact on plastics processing. They are highly recommended for objects requiring long-lasting antimicrobial action and for engineering polymers that are processed at high temperatures. |
