zbec (zinc dibenzyl dithiocarbamate) is a primary accelerator for natural and synthetic rubber. its chemical formula is c30h28n2s4zn. it functions by forming a complex with the sulfur and rubber polymer, which cross-links the polymer chains. this cross-linking process is what gives the rubber its elasticity and strength.
classification of accelerators rubber field info,sulfenamide class. the sulfenamide class of accelerators, including cbs, tbbs, mbs, dcbs, and others, is widely utilized in the tire industry due to their delayed action and accelerated curing rate when vulcanizing rubber compounds containing furnace blacks. sulfenamide accelerators are produced through the reaction of 2-mercaptobenzothiazole
recent advances in the devulcanization technologies of
the demand for rubber products has grown steadily over the last years [9, 10]. global nr production in 2018 amounted to almost 13.9 million metric tonnes, the vast majority of which (91%) has been produced by the asia pacific region, while the production of europe, middle east, and africa (emea) was approx. 6.5%.

zinc-based curing activators: new trends for reducing zinc
the efficiency of sulfur vulcanization reaction in rubber industry is generally improved thanks to the combined use of accelerators (as sulphenamides), activators (inorganic oxides), and co-activators (fatty acids). the interaction among these species is responsible for the formation of intermediate metal complexes, which are able to increase the reactivity of sulfur towards the polymer and to

- What type of rubber is used for vulcanization?
- Since most of the research on devulcanization has been made on waste tires, this review mainly focuses on the most widely used rubber classes for this application, i.e., natural rubber (NR) and styrene-butadiene rubber (SBR), and the most common vulcanization technique, i.e., sulfur vulcanization.
- What is devulcanization of post-consumer rubber?
- Devulcanization of post-consumer rubber is the most desirable approach to solving the problem of rubber waste management.
- Can reclaimed rubber be used as a devulcanized rubber?
- Hence, reclaimed/devulcanized rubber can only be used for less demanding functions and, according to the application, it can be used either as obtained or mixed in different amounts with virgin rubber or other polymers, where it can significantly reduce the cost of the final products (see Chapter 4). 2.4. Introduction to devulcanization methods
- How is vulcanized rubber broken down?
- In ambient grinding, the vulcanized rubber is broken down mechanically at room temperature. The mill type and the number of grinding steps determine the final size distribution of the rubber particles. This process is generally easy and inexpensive, but the price can become very high if a very fine mesh size is required.
