nobs is a post-effect vulcanization accelerator with short vulcanization time, excellent scorch resistance and safe processing. suitable for natural and synthetic rubbers. mainly used in the manufacture of tires, hoses, rubber shoes, conveyor belts and other industrial rubber products. packaging:
select accelerators for rubbers specialchem,the term accelerator is very appropriate in that it succinctly describes the function of the additive. however, there is often confusion resulting from misuse or overuse of the term. an accelerator has the following unique properties.

it is of sulfide crosslinking with more sulfur key is given priority to, but can small, sulfur key key unstable, easy to change, and so the heat ageing performance is poor, in the process of tyres used are easy to be returned to the original sulfide phenomenon, which affect the actual use of the tire life.for this reason, we decided to tire

rubber vulcanizing accelerators based on classification of rubber vulcanizing accelerators rubber accelerator
in rubber tire production, three popular types of rubber vulcanizing accelerators exist that are similar in appearance (i.e., 2-mercaptobenzothiazole, 4,4′-dithiodimorpholine, and tetramethyl thiuram monosulfide). because the rubber vulcanizing accelerator has a great influence on the vulcanized rubber characteristics, it is necessary to classify and identify the three popular types of

normally, this process is conducted by heating the mixture of raw rubber with vulcanizing agents at specific vulcanization time in a pressurized mold. three types of the vulcanizing agent are extensively used; the sulphur, insoluble sulphur, and peroxides. after all, sulphur is the most generic vulcanization agent as it is easily available

- What vulcanizing agent is used in rubber?
- Elemental sulfur is the predominant vulcanizing agent for general-purpose rubbers. It is used in combination with one or more accelerators and an activator system comprising zinc oxide and a fatty acid (normally stearic acid). The most popular accelerators are delayed-action sulfenamides, thiazoles, thiuram sulfides, dithocarbamates and guanidines.
- Which accelerators are suitable for natural rubber and synthetic rubber?
- We supply both primary and secondary accelerators that are suitable for both for natural rubber and synthetic rubber compounds including NR, CR, SBR, NBR, BR, EPDM and chlorobutyl rubber. We offer a wide range of cure speeds from delayed action to ultra-accelerators.
- What determines vulcanization rate?
- The accelerator determines the rate of vulcanization, whereas the accelerator to sulfur ratio dictates the efficiency of vulcanization and, in turn, the thermal stability of the resulting vulcanizate. Certain elastomers such as chloroprene can be vulcanized by the action of metal oxides such as zinc oxide as well as sulfur.
- Why are accelerators used in vulcanizing elastomers?
- Accelerators are added in small amounts to speed up the curing of adhesives by reducing the cure time and temperature of elastomers, particularly latex systems. The selection of an accelerator will depend on the specific vulcanizing system and curing properties.
