Tellurium diethyldithiocarbamate

Tellurium diethyldithiocarbamate (CAS 20941-65-5) is an organometallic accelerator used in rubber vulcanization and polymer processing. It delivers exceptionally fast cure rates at low temperatures. This chemical is a preferred choice where conventional sulfur accelerators fall short. In rubber compounding, it functions as an ultra-accelerator for natural and synthetic rubber types.

It enables low-temperature vulcanization in products such as latex goods, sponge rubber, and extruded profiles. Cable insulation manufacturers use it where rapid, controlled crosslinking is required. In polymer systems, it acts as a polymerization initiator and catalyst. This supports the production of specialty elastomers with defined molecular weight targets for industrial use.

Tire and industrial rubber goods producers select it when cure speed and scorch safety must be balanced. It is effective against demanding performance specifications in modern manufacturing. The product is supplied as a grey to yellow powder or as pre-dispersed rubber masterbatch forms. These formats allow for easier incorporation into various compound recipes and batches.

Technical grade is the standard market offering for this material. Purity specifications are typically confirmed by active ingredient content and metal assay to ensure consistency. Packaging is available in multi-kilogram quantities suited to industrial compounding operations. This ensures a reliable supply chain for large-scale rubber and polymer production facilities.
