TBzTD can lead to high processing safety and faster cure rate as an accelerator of natural rubber and synthetic rubber vulcanization. TBzTD satisfies requirements of“Technical Regulations for Dangerous Materials” TRGS 552 about toxicity of nitrosamines in Germany and not release carcinogenic nitrosamines during vulcanization. Addition of thiazoles or sulfenamides accelerators can slow the vulcanization, shorten scorching and vulcanization time and vulcanization without significant increases . It can be activated by alkaline accelerators such as aldehyde- amines and guanidines.

Compared to traditional TBzTD powders, TBzTD-70GE F140 allows:

Dust free products with a complete filtration up to 100µm, no skin sensitization, health guard of operators.

Effective guarantee of activity of TBzTD due to pre-dispersed masterbatch.
