CBS (CZ) is a delayed-action rubber vulcanization accelerator used to balance curing speed, scorch safety, and final compound performance in natural rubber and synthetic rubber systems. For B2B buyers, its main value is in helping match the accelerator to the rubber type, processing window, and end-use requirements.
CBS (CZ), chemically known as N-cyclohexyl-2-benzothiazolesulfenamide, is a widely used rubber accelerator with the CAS number 95-33-0. It is commonly supplied as a gray-white to light-yellow powder or granule and is used in rubber compounding to improve vulcanization efficiency.
Henan GO Biotech provides CBS (CZ) for industrial rubber applications, including formulations for natural rubber, reclaimed rubber, and ethylene-based synthetic rubber systems, with especially notable use in SBR compounds.
| Item | CBS (CZ) Characteristics | Practical Meaning |
|---|---|---|
| Chemical name | N-cyclohexyl-2-benzothiazolesulfenamide | Standard technical identification for industrial procurement |
| Action type | Delayed accelerator | Supports safer processing before full cure develops |
| Scorch safety | Good anti-scorch performance | Helps reduce premature vulcanization risk during mixing and shaping |
| Curing behavior | Short curing time after activation | Supports efficient production cycles |
| Odor and stability | Low odor, stable performance | Useful for general industrial rubber formulations |
| Compatibility | Natural rubber, reclaimed rubber, synthetic rubber, especially SBR | Suitable for a wide range of compounding systems |
Because CBS (CZ) is a technical rubber additive, the final selection should always consider the compound recipe, processing temperature, curing target, and downstream application.
CBS (CZ) works by providing a controlled vulcanization response in rubber compounds. Its delayed-action profile allows the compound to remain processable during mixing, extrusion, or molding, while still supporting efficient curing when the vulcanization stage begins.
In practical terms, this means the accelerator helps balance two goals: processing safety before cure and curing efficiency during vulcanization.
This mechanism is one reason CBS (CZ) is often considered in formulations where scorch safety and stable production behavior are important.
| Rubber system | Typical role of CBS (CZ) | Selection focus |
|---|---|---|
| Natural rubber (NR) | Used to support controlled curing and good scorch safety | Useful when the compound needs a balanced processing window and stable cure response |
| SBR | One of the more common application systems for CBS (CZ) | Often selected for efficient curing behavior and practical manufacturing stability |
| BR | Can be used in synthetic rubber compounding where the recipe supports it | Selection depends on the full accelerator package and performance target |
CBS (CZ) is not a one-size-fits-all choice. The best result depends on the rubber type, the rest of the formulation, and the manufacturing process.
For procurement and formulation teams, the key question is not whether CBS (CZ) is “better” in every case, but whether it fits the curing profile required by the compound.
| Comparison point | CBS (CZ) | General comparison view |
|---|---|---|
| Scorch safety | Generally favorable | Often preferred when processing stability matters |
| Curing speed | Efficient after activation | May be selected when a balanced cure profile is needed |
| Compound fit | Strong in NR, SBR, and selected synthetic rubber systems | Comparable options may be chosen when a faster or different cure curve is required |
| Formulation logic | Can be used alone or in combination with other accelerators such as D, DT, TT, or TS | Blends are often evaluated for the target cure system rather than a single additive decision |
In short, CBS (CZ) is often a practical choice when buyers want a balance of safety, cure efficiency, and broad applicability, while other accelerators may be considered when a different curing curve is required.
CBS (CZ) is used in a wide range of rubber products where consistent vulcanization performance is important.
Because CBS (CZ) has a bitter taste, it is not suitable for food-related products.
Henan GO Biotech supports B2B buyers with CBS (CZ) supply for industrial compounding needs, including OEM-oriented procurement options when required.
CBS (CZ) is a versatile rubber vulcanization accelerator whose value lies in its balanced curing profile, good scorch safety, and broad use across natural rubber and synthetic rubber systems. For B2B buyers, the most reliable selection method is to match the accelerator to the compound recipe and the processing requirements. Henan GO Biotech supplies CBS (CZ) with a focus on technical consistency, industrial suitability, and practical application support.
