What is Rubber Accelerator CBS CZ CAS 95-33-0?

Rubber Accelerator CBS, also called CZ, is N-cyclohexyl-2-benzothiazolesulfenamide. It is a delayed-action sulfenamide accelerator used to vulcanise sulphur-cured natural-rubber and synthetic-rubber compounds.

Are CBS and CZ the same rubber accelerator?

Yes. CBS and CZ are common names for N-cyclohexyl-2-benzothiazolesulfenamide, CAS 95-33-0. The chemical identity is the same, although powder, oiled-powder and granule forms may be selected differently for the compounding process.

Which CBS specifications should be checked before use?

Check the offered form and appearance, initial melting point, heat loss, ash and sieve residue for powder or granular material. Commercial rubber-accelerator grades commonly specify an initial melting point of at least 96-99 deg C, with the final acceptance based on the approved compound specification.

How should Rubber Accelerator CBS be stored?

Store CBS in a cool, dry, well-ventilated area in tightly closed containers, away from direct sunlight. Supplier-stated storage life is commonly 6 months to 1 year, so the selected grade should be used or retested within the stated period.

Is Rubber Accelerator CBS soluble in water?

No, CBS is essentially insoluble in water and has a density around 1.31-1.34 g/cm3. It is soluble in benzene and several organic solvents, with only slight solubility in gasoline, which is relevant for handling and cleaning operations.

Product Description

Rubber Accelerator CBS (CZ) CAS 95-33-0 is N-cyclohexyl-2-benzothiazolesulfenamide, with EC 202-411-2 and molecular formula C13H16N2S2.

Synonyms: CBS; CZ; N-Cyclohexyl-2-benzothiazolesulfenamide.

CAS: 95-33-0.

Molecular formula: C13H16N2S2.

It is supplied as a grey-white to light-yellow powder or granules.

It is positioned as a delayed-action sulfenamide accelerator for sulphur-vulcanised natural and synthetic rubber compounds.

It provides processing safety and resistance to premature scorch at ordinary processing temperatures.

Once curing starts, it gives a comparatively short vulcanisation time.

It is suitable as a primary accelerator in tires and technical rubber goods.

CBS and CZ are common names for the same chemical, CAS 95-33-0.

It is essentially insoluble in water and has a density around 1.31-1.34 g/cm3.

Commercial grades commonly specify an initial melting point of at least 96-99 C.

Confirm offered form and appearance, initial melting point, heat loss, ash, and sieve residue for powder or granular material.

Store in tightly closed containers in a cool, dry, well-ventilated area, away from direct sunlight.

Use suitable PPE when handling the material to prevent dust or granule exposure and skin or eye contact.

Confirm packaging suitable for the solid form and order quantity, and follow the current SDS.

Confirm grade, packaging, and specification as required.
