Structural type
Characteristics and uses: TBBS is suitable for NR, SBR, Br and their mixtures, with fast curing speed and high modulus of vulcanizate. The MBTS / DPG system can be effectively replaced by a small amount of overspeed accelerator alone or in combination in the formulation of tire or rubber industrial products. When the dosage is lower than 10%, the same modulus as CBS or MBS can be obtained.
