Use of TBzTD as Noncarcinogenic Accelerator for ENR/SiO2
The resulting ENR 40 was melt mixed with three loadings of nSiO 2 (1, 2, and 3 phr) and then vulcanized as usual in a sulfur curing system using TBzTD as a noncarcinogenic accelerator, which resulted into nitrosamine free cure.

Accelerator TBzTD has been developed to replace thiurams such as TMTD in cases where the presence of harmful nitrosoamines is of concern. The dibenzylnitrosoamine is not carcinogenic, according to published literature. TBzTD is a fast curing primary or secondary accelerator and sulfur donor in NR, SBR and NBR applications.

TBzTD and CBBS - alternative accelerators for reducing
TBzTD and CBBS are two new chemicals that have minimized the generation of nitrosamines associated with many of the common rubber accelerators in use today. Substitutions of volatile nitrosamine-generating accelerators in model compounds of various polymers and applications showed TBzTD to be a good replacement for accelerators such as TMTD and TETD, although some curative adjustments are usually necessary.

requires 40 to 55 sulphur atoms (in the absence of accelerator). The process takes around 6 hours at 140°C for completion, which is uneconomical by any production standards. The vulcanizates thus produced are extremely prone to oxidative degradation and do not possess adequate mechanical properties for practical rubber applications.
