Nitrosamine free sulfur donor

The Vultac® polymer does not contain nitrogen: it cannot generate carcinogenic nitrosamines during cure.
A case study demonstrates that Vultac® is highly efficient to replace Thiurams in combination with Thiazoles or Sulfenamides in Bromobutyl (BIIR) based car and trucks innerliner compounds.


The following table demonstrates that Vultac® is the right compromise to get a nitrosamine free and cost effective solution.

Sulfur donor NA Status Efficiency Price General conclusion
DTDM - ++ ++ very cost effective, but NA generating
TMTD - ++ ++ very cost effective, but NA generating
TBzTD +/- + +/- reasonably cost-effective, but only NA-safe
CLD + +/- - NA free, but expensive
SDT + +/- - NA free, but expensive
Vultac + ++ + NA free, cost effective
