Carbon Black N660

Functional Fillers & Reinforcing Agents
Carbon Black N660.
BOAO N660 is the easiest processing grade among standard carbon blacks, with the lowest surface area and particle structure optimized for minimal mixing energy requirements. It provides good dispersion characteristics and adequate reinforcement for general-purpose applications. N660 is ideal for high-volume production where processing efficiency and cost optimization are critical factors without compromising basic performance requirements. Primary Applications: Commercial tyres, conveyor belts, industrial rubber products, commodity rubber goods Secondary Applications: Shoe soles, weatherstripping, industrial hoses, general-purpose rubber compounds
