Vulcanization accelerator is one of the essential raw materials in rubber industry.Part of the secondary amine structure of the promoter in the process of rubber processing and air nitrogen oxides reaction, easy to produce carcinogenic substance nitrosamines.This kind of variety of accelerator is NOBS, TMTD, TETD, TMTM, DIBS, OTOS, PZ, DZ, etc.

While some vulcanization promoters are banned, people are actively looking for alternatives or developing new types of promoters that do not produce nitrosamines.The promoter TBBS(NS) is a primary amine structure, which does not have the problem of producing nitrosamine toxic substances. Its performance is similar to that of the promoter NOBS, so it receives much attention and its production and development speed also increase rapidly.

The research and development of promoter TBBS began in the early 1980s, but due to the technical problems in the synthesis of raw material tert-butyramine, the progress was not rapid.In recent years, many restrictions on the use of promoters have been issued in the world, which has attracted the attention of the rubber processing and additive industry in China, and the output of NOBS in China is also gradually decreasing.

At present, the development of domestic TBBS involves two problems. One is the development of raw material tert-butylamine. If it is produced by urea method, the cost of TBBS will be too high for users to accept.The other is that the TBBS market has yet to open.At present, the largest domestic consumption is still NOBS, while TBBS sales volume is still very small.Although in the long run, with the increase of domestic restrictions on NOBS, if the price of TBBS is controlled at an appropriate price, its market prospect is very good, but its market share is not high in the near future.
