What is 2-(tert-butylaminothio)benzothiazole?
2-(tert-Butylaminothio)benzothiazole (CAS 95-31-8), commercially known as TBBS, is a delayed-action sulfenamide accelerator for rubber vulcanization.
Where is 2-(tert-butylaminothio)benzothiazole used?
- Tire manufacturing: tread compounds, sidewalls, carcass plies
- Industrial rubber goods: conveyor belts, seals, hoses, gaskets
- Footwear and technical molded components: dimensional accuracy and surface quality
- It performs in natural rubber, SBR, and blended systems, often with DPG or TMTD.
Good to know: It controls the rate and onset of crosslinking, providing a processing safety window before cure begins. Granular form is preferred in automated dosing and mixing to reduce dust exposure.
Commercial specifications
- Purity benchmarks typically 95% minimum active content
- Standard commercial grades meet major rubber industry quality frameworks
