What Is Dibenzothiazole Disulfide (MBTS)?
MBTS is dibenzothiazole disulfide, a thiazole-family rubber accelerator identified by CAS 120-78-5. It is used in selected sulfur-vulcanization packages for natural rubber and synthetic elastomers. The disulfide differs from mercaptobenzothiazole, often abbreviated MBT.
The TDS sets initial melting point ≥166°C, heating loss ≤0.40%, ash ≤0.50% and residue on a 150 µm sieve ≤0.10%. The melting-point value is a temperature, correcting the percentage unit shown in the old web table. Powder and granule handling should be matched to the mixer and feeding system.
For NR, SBR and related elastomer compounds, evaluate MBTS with sulfur, activators and the complete accelerator system. Compare scorch time, cure rate, crosslink development and processing safety using rheometer and application trials. Determine addition levels from the actual recipe rather than a universal dosage.
Tires, molded rubber and industrial elastomer articles require evaluation of mechanical properties and service ageing after cure. Protect powder from moisture and contamination. For sea and air shipment the matched reference identifies Class 9, UN 3077; prevent skin exposure and environmental release.
