What is Zinc dibenzyldithiocarbamate?
Zinc dibenzyldithiocarbamate (CAS 14726-36-4), commercially known as ZBEC, is a zinc dithiocarbamate accelerator used in rubber vulcanization.
Where is Zinc dibenzyldithiocarbamate used?
- Rubber compounding: primary or secondary accelerator in sulfur-cured natural rubber, SBR and EPDM systems for seals and gaskets
- Automotive components
- Latex: room-temperature or low-temperature vulcanization where thiuram accelerators raise regulatory concerns
- Tires and technical rubber goods: cleaner toxicological profile without sacrificing cure rate
- It also acts as a secondary accelerator alongside sulfenamides to boost crosslink density in mechanical rubber goods.
Good to know: It drives efficient sulfur crosslinking at processing temperatures while offering low nitrosamine generation, a factor increasingly driving purchasing decisions in rubber compounding.
Commercial specifications
- Purity confirmed by active content assay and melting point
- Pre-dispersed masterbatch forms from some suppliers improve handling and dispersion
