The accelerator CBS has excellent comprehensive properties and accounts for a large proportion of the total accelerator output.

Accelerator CBS, also known as accelerator CZ, accelerator CM, chemical name N-cyclohexyl-2-benzothiazole sulfenamide, molecular formula C13H16N2S2, appearance is white or light gray powder with slight odor. The accelerator CBS is insoluble in water, slightly soluble in ethanol and gasoline, soluble in benzene, acetone, ethyl acetate, methylene chloride, carbon tetrachloride, etc., and can be decomposed by long-term heating. Accelerator CBS is a sulfenamide rubber vulcanization accelerator.

There are many types of rubber vulcanization accelerator products, mainly including sulfenamides, thiazoles, thiurams, dithioformates, guanidines, etc. Among them, sulfenamides have excellent comprehensive properties and are the most widely used and in demand. maximum. Accelerator CBS is a type of sulfenamide rubber vulcanization accelerator. It is a post-effect semi-super speed accelerator. It also has the advantages of good scorch resistance and fast vulcanization speed. It can be used alone or with other rubbers. Used with vulcanization accelerator.

The accelerator CBS can be added to natural rubber, styrene-butadiene rubber, nitrile rubber, isoprene rubber, EPDM rubber and other rubbers. In addition to excellent scorch resistance and vulcanization speed, it also has slight discoloration, It has the advantages of no blooming, wear resistance, crack resistance, aging resistance, and high safety. It can be widely used in manufacturing fields such as tires, shoemaking, cables, tapes, and hoses.

The preparation of accelerator CBS generally uses accelerator M (2-mercaptobenzothiazole) and cyclohexylamine as raw materials. After adding water and mixing thoroughly, sodium hypochlorite is added as an oxidant. The crude product is obtained through an oxidation reaction, and then separated, washed, dried and other processes are used. Get the finished product. This method has a simple process, low equipment requirements, easy control of the production process, easy availability of raw materials, and high yield. However, it will produce a large amount of wastewater. The use of new and more environmentally friendly oxidants to replace sodium hypochlorite has become a research focus.

According to the “2022-2026 Promoter CBS (CZ) Industry In-depth Market Research and Investment Strategy Suggestion Report” released by the Industrial Research Center It shows that on a global scale, China is the main accelerator producer, and the global accelerator CBS production capacity is mainly distributed in mainland China. The annual output of accelerator CBS in my country accounts for about 23% of the total accelerator output. The accelerator CBS is one of the largest rubber vulcanization accelerator categories in my country. The main accelerator CBS manufacturers in my country include Yanggu Huatai, Kelly Chemical, Hebei Kemai, Lianyungang Sennics, Langrun New Materials, etc.

Industry analysts said that in November 2021, the price of accelerator CBS in my country reached a new high, and has continued to decline since then until January 2022. It fell to the bottom and gradually recovered since February. From the perspective of raw materials, domestic aniline, accelerator M, and cyclohexylamine companies have started operations one after another after the Spring Festival, and the supply and price of raw materials are relatively stable; from a production perspective, the production cost of accelerator CBS is relatively high; from a market perspective, the impact of the new crown epidemic Under this situation, foreign tire and other industries have weak demand for the accelerator CBS. It is expected that in the first half of 2022, the possibility of a significant increase in the price of accelerator CBS is low.
