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. Composition 80% finely selected zinc oxide, 20% epdm/eva binder and dispersing agents Appearance White or bronzing granule Density Approx. ~ 2.2 g / cm3 (20¡ãc) Raw material characteristics of zno Melting point ~ 195-200 ¡ãc Loss on ignition ¡ü 0.1% Zno content ¡ý 99.8% Sieve residue 63µm ¡ü 0.1% 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. Dosage Levels 3 - 8 phr Applications curing activator, particulary in the presence of fatty acids for almost kinds of rubbers. Storage Storage stability in original closed containers under cool and dry conditions max. 2 years. 25kg/bag
