Some research works have shown that the primary factors of carbon black (CB) influencing elastomer reinforcement include three parts: (1) the primary particle size or specific surface area; (2) The structure or the degree of irregularity and (3) the surface activity (with regard to filler-filler and filler-polymer interaction) [1, 2]. It was discovered [3] that high-structure CB ( e.g. DZ13) has better reinforcement effect in bound rubber than common CB ( e.g. N330 and N660) due to its high degree of structuration and high surface activity.
