Influence of accelerator type on properties of NR
The results clearly than MBTS. reveal that the storage moduli (E0 ) of TMTD-cured As regards the effect of accelerator type on and TBBS-cured blends are relatively high com- crosslink density of the EPDM phase, it is found pared to those of MBTS-cured and MBT-cured that the greatest crosslink density (or the lowest blends.
WESTCO™ MBTS Accelerator. Benzothiazole disulfide. CAS# 120-78-5. WESTCO™ MBTS accelerator for rubber is a general purpose accelerator for sulfur cures. It is very active above 142°C (287°F). Unlike thiuram disulfides, WESTCO™ MBTS does not split off active sulfur during vulcanization. For use in natural and synthetic rubber processing.

The later reacts with another MBT molecule in the presence of zinc to form another MBTS-zinc complex. Assuming a radical mechanism 6, the cross-link precursor cleaves homolytically into a rubber-polysulfide and polysulfidic benzothiazole radical. The later reacts with rubber to form a new cross-link precursor whereas the polymeric persulfenyl
