Ang thiuram at dithiocarbamate accelerator .
Sa kasalukuyan, ang zinc dibutyl dithiophosphate ay pangunahing ginagamit sa ibang bansa upang gumawa ng para sa mga pagkukulang na ito . sa mga nagdaang taon, ang dayuhang bagong ligtas na thiura-type na accelerator, tetrakilyl sulfuram thiuram (tbztd) at tetrakis-(2- ethylhexyl) thioacetate (tot-n) introduced. Because TBZTD and TOT-N have large molecular weight, high melting point and difficult to decompose, nitrosamines will not be produced. In particular, TBZTD only has a slightly lower vulcanization rate than TMTD. Other physical properties are almost the same as TMTD, and it has become a promising potential.
