Use Characteristics Konson® ZnO-80 is a special grade of zinc oxide particularly suitable for the rubber industry. Due to its EPDM elastomer bound form, the absorption of humidity from the atmosphere during storage is prevented. In comparison to extrusion compounds containing powdered zinc oxide, those with Konson® ZnO-80 provide smoother profiles. This is due to the more homogeneous dispersion of Konson® ZnO-80. A slight increase in modulus and tensile strenghth usually occurs; elongation at break is also improved. Konson® ZnO-80 prevents the heat swell which normally occurs when powdered zinc oxide is used in CR mixes
Processing Advantages The thermoplastic, excellent compatible EPDM/EVA binder which is combined with active dispersing promoters allows much more easily and quickly incorporation and excellent dispersion in the rubber mixing. In this way, optimal activity of the effective ZnO is assured.
