STERLING® NS

STERLING® NS carbon black is a pelleted carbon black-based rubber compound. It shows low viscosity and generates relatively little heat in processing. It possesses higher die swell and extrusion shrinkage than other ASTM furnace grades at equal carbon black loadings, except for ASTM N772 and N762 type carbon blacks, in rubber compounds containing STERLING NS carbon black. it shows dispersion, higher modulus, viscosity and lower die swell. It exhibits very low surface area as ASTM N772 and N762 type carbon blacks, but with a higher structure reflected by the higher OAN and C-OAN. In this additive, low surface area and low structure allow high loading to be used in many rubber compounds, by reducing permeability, compound cost and swelling in adverse environments. STERLING® NS finds application in tires (tube and inner-liner compounds), industrial rubber products like seals and gaskets, windscreen wiper blades, anti-vibration and engine mountings, hose linings and other extruded articles.
