Hidispersion zno-80/product description
Use characteristics hidispersion 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 hidispersion zno-80 provide smoother profiles. This is due to the more homogeneous dispersion of hidispersion zno-80. A slight increase in modulus and tensile strenghth usually occurs; elongation at break is also improved. Hidispersion zno-80 prevents the heat swell which normally occurs when powdered zinc oxide is used in cr mixes.
