Applications
Uses: Delayed-action sulfenamide accelerator. TBBS has the ability to provide fast efficient mixing of difficult, highly loaded carbon black reinforced compounds without sacrificing scorch safety or physical properties. Its vulcanizates have good reversion and aging resistance.

Polymers: Natural rubber and most synthetic elastomers. Especially good with SBR.

Synergism: TBBS cure performance can be boosted with thiuram or guanidine accelerators.

Cure Effect: Promotes a fast cure rate with good scorch safety. Can use 10% less TBBS than CBS.

Crosslink Type: TBBS promotes a balance of mono-, di- and poly-sulfidic crosslinks resulting in vulcanizates with a good balance between heat aging resistance and tear resistance.
