In high-stakes rubber manufacturing—whether for high-performance tires or heavy-duty industrial belts—precision is everything. The margin for error during the processing phase is slim. To maintain high throughput without risking premature vulcanization, manufacturers require an accelerator that offers exceptional control.
This is where N-tert-butyl-2-benzothiazolesulfenamide, commonly known as TBBS or NS, excels.
At Qingdao Chengda Huili Import and Export Co., Ltd., we specialize in supplying top-tier rubber additives that empower manufacturers to push the limits of their production capabilities.
What is Accelerator TBBS (NS)?
TBBS (NS) is a delayed-action sulfenamide accelerator. While it shares the benzothiazole lineage with other common accelerators like CBS (CZ), it is chemically distinct due to its bulky tert-butyl group.
This specific molecular structure is what grants TBBS its defining characteristic: extended scorch safety.
The Technical Edge: TBBS (NS) vs. CBS (CZ)
While both are industry staples, TBBS (NS) is the preferred choice when processing conditions are more demanding.
- Superior Scorch Delay: TBBS provides a longer delay period before the onset of cure compared to CBS. This extra time is crucial when processing large, thick rubber compounds or when operating at higher processing temperatures. It effectively prevents “scorching” (premature curing) in the extruder or mold.
- High Modulus: Once curing begins, TBBS promotes a fast and strong vulcanization rate, resulting in vulcanizates with high modulus and excellent resilience.
- Performance Stability: It offers robust physical properties and good aging resistance, making it suitable for products that face harsh operating environments.
Key Applications
Because of its balance between processing safety and final product strength, our TBBS (NS) is essential for:
- Radial Tires: Used extensively in tire treads and carcasses where heat buildup during processing is a concern.
- Industrial Belting: Ideal for conveyor belts that require thick rubber layers and uniform curing.
- Shock Absorbers & Hoses: Perfect for technical goods requiring high elasticity and durability.
