STERLING® SO-1

STERLING® SO-1 by Cabot is a semi-reinforcing carbon black, the material of the class previously known as Fast Extrusion Furnace-Low Structure (“FEF-LS”). It conforms to ASTM N539 carbon black target values. It exhibits similar surface area and aggregate size to ASTM N550 type carbon black, with a lower degree of particle aggregation structure. It offers lower hardness, modulus and slightly greater die swell. It provides good dispersion, higher loading capacity, resilience and lower levels of reinforcement. It is designed for industrial rubber products like extruded profiles, hoses, seals and moldings. STERLING® SO-1 is also applicable in tires and carcass.
