Are CBS and CZ the same rubber accelerator?

CBS and CZ are common names for N-Cyclohexyl-2-benzothiazolesulfenamide, CAS 95-33-0. Confirm the offered grade, physical form and batch release values because powder and granule forms may be selected differently for the compounding process.

Should CBS powder and CBS granules be treated as interchangeable?

Not without checking the processing requirement. Both forms can have the same chemical identity, but dust control, feeding behaviour and sieve specification can differ. Select the physical form that matches the existing compounding and handling equipment.

Which CBS release values should be confirmed before use?

Confirm the agreed initial melting point, heating loss and ash first. For powder or granular grades, applicable sieve-residue and particle-size limits should also be matched to the specified formulation and processing conditions.

Rubber Accelerator CBS (CZ) CAS 95-33-0

Rubber Accelerator CBS (CZ) CAS 95-33-0, also known as CBS, CZ or N-Cyclohexyl-2-benzothiazolesulfenamide, is a delayed-action rubber accelerator for sulphur-vulcanised natural and synthetic rubber compounds. MBTS is a related thiazole accelerator selected for different cure-rate and scorch-safety requirements.

Powder and granule grades are supplied in PE-lined 25 kg bags; COA, TDS and SDS are available for the offered grade.

Product Introduction

Rubber Accelerator CBS (CZ) (CAS 95-33-0), N-cyclohexyl-2-benzothiazole sulfenamide, is supplied as a delayed-action sulfenamide accelerator for sulphur-vulcanised rubber compounds. We offer CBS for approved tire and technical-rubber formulations requiring a primary accelerator with the required processing and cure profile.

Applications

Tire compounds, including passenger, truck and selected technical-rubber formulations.
Rubber hoses, belts, cable compounds, seals and moulded goods using a CBS/CZ cure system.
Natural-rubber and synthetic-rubber compounds specifying a sulfenamide accelerator.
Rubber masterbatch and compound manufacture using powder, oiled-powder or granule CBS grades.

Grade and Supply Details

We confirm the required product form, assay, initial melting point, heating loss, ash, sieve residue, free-amine limit and stated test method against the compound specification. CBS is normally offered as grey-white to light-yellow powder or granules in 25 kg lined bags. A batch COA, with the applicable TDS and SDS, is available for the offered material.

FAQ - Technical & Supply Chain

Q:
Are CBS and CZ the same rubber accelerator?

A: CBS and CZ are common names for N-Cyclohexyl-2-benzothiazolesulfenamide, CAS 95-33-0. Confirm the offered grade, physical form and batch release values because powder and granule forms may be selected differently for the compounding process.
Q:
Should CBS powder and CBS granules be treated as interchangeable?

A: Not without checking the processing requirement. Both forms can have the same chemical identity, but dust control, feeding behaviour and sieve specification can differ. Select the physical form that matches the existing compounding and handling equipment.
Q:
Which CBS release values should be confirmed before use?

A: Confirm the agreed initial melting point, heating loss and ash first. For powder or granular grades, applicable sieve-residue and particle-size limits should also be matched to the specified formulation and processing conditions.
