A key element in the design is the accelerator combination: for instance Figure 1 and Table 1 show that if the primary accelerator is a benzothiazole such as MBTS or sulphenamide such as CBS, vulcanisation will be faster whichever secondary accelerator is chosen, be it a guanidine such as DPG or thiuram such as TMTD,
Sulfur forms ring and chain structures as it is the second only to carbon in exhibiting catenation. The 8-membered ring and shorter chain structure of sulfur molecule is important in vulcanization process which individual polymers are linked to other polymer molecules by atomic bridges.
Vulcanization & Accelerators Vulcanization is a cross linking process in which individual molecules of rubber (polymer) are converted into a three dimensional network of interconnected (polymer) chains through chemical cross links(of sulfur). The vulcanization process was discovered in 1839 and the individuals responsible for this discovery were
Accelerator, in the rubber industry, is added with a curing agent to speed the vulcanization. Accelerators contain sulfur and nitrogen like derivatives of benzothiazole and thiocarbanilides. The popular accelerators are sulfenamides (as a delayed-action accelerators), thiazoles, thiuram sulfides, dithocarbamates and guanidines.
Results. Synthesized safe amine-based thiuram disulfides in combination with MBTS display strong synergism in the gum vulcanization. Higher concentration of thiuram disulfide in presence of MBTS (6:3 mM ratio) shows better results with respect to cure and physical properties.
choice of accelerator in the process of sulfur vulcanization determines the kind of network structure and consequently leads to the specific material properties. The chosen accelerator affects the cure rate and scorch safety, as well as the number and the average length of the formed crosslinks.
- Vocol ZBPD is mainly used as an accelerator in non-blooming, relative low cost, fast curing systems for EPDM. - When used in combination with Perkacit MBTS or sulfenamides in NR compounds, Vocol ZBPD dramatically improves reversion resistance. Because of its non-amine based structure, Vocol ZBPD
