What is Zinc mercaptobenzothiazole?
Zinc mercaptobenzothiazole (CAS 155-04-4), abbreviated ZMBT and also marketed as Bantex, is an organozinc compound used as a primary accelerator and stabilizer in rubber vulcanization.
Where is Zinc mercaptobenzothiazole used?
- Rubber compounding: accelerates sulfur vulcanization in natural and synthetic rubbers, including NR, SBR, and NBR
- Tires: incorporated into tread and sidewall compounds
- Plastics processing: stabilizer that inhibits thermal degradation during extrusion and molding
- Latex systems: secondary accelerator
- It improves crosslink density in dipped goods and coated fabrics.
Commercial specifications
- Purity typically 95% or above
- Bulk bags and smaller packaged units
