  • What is Westco TBBS accelerator for rubber?
  • Technical Data: TBBS accelerator for rubber is a delayed action accelerator for use in natural rubber and synthetic rubbers such as SBR, BR, NBR and EPDM. It has lower scorch than CBS and can be more safely processed. It has slightly faster scorch than OBTS.
  • How does dibenzyldithocarbamate improve SBR vulcanization efficiency?
  • Dibenzyldithocarbamate derivative applied with other accelerators (especially CBS) effectively enhances the efficiency of SBR vulcanization by reducing the optimal vulcanization time and increasing the crosslink density of the vulcanizates despite the lower amount of ZnO.
  • Is eptd/CBS better than TMTD in vulcanization of rubber?
  • The results indicated that EPTD/CBS has better scorch safety, cure rate index and mechanical properties compared to that of the unsafe TMTD during the vulcanization of rubber. Moreover, alkyl, instead of aryl substitution, on piperazine can enhance the reactivity of the synthesized thiuram disulfide.
