Carbon Black N660 is recommended to be used in cord layer of tires, inner tubes, bicycle tires, rubber tubes, rubber tapes, cable ropes, shoes kind, and patterns.
N660 fits for all kinds of rubber, it has more complicated structure, smaller particles, and higher dispersion than half-reinforcing carbon black. The tensile strength, the tear resistance, and the tensile stress at a given elongation of vulcanized rubber are very high.
