The accelerator MBS is highly toxic and the market space is gradually shrinking

Accelerator MBS, namely 2-benzothiazolyl-N-morpholinyl sulfide, also known as N-oxydiethylene-2-benzothiazole sulfenamide, 2-(4-morpholinylthio)benzene Thiazole, 2-benzothiazolyl-N-morpholinyl sulfide, accelerator NOBS, etc., is a post-effect vulcanization accelerator for the initial stage of sulfenamide vulcanization, CAS No. 102-77-2, pure The product is light yellow needle-shaped crystals, and the industrial product is light yellow or orange-yellow particles (or powder). It is easy to decompose when exposed to heat and is soluble in various organic solvents such as benzene and acetone.

The accelerator MBS has the advantages of long scorch time, safe operation and good physical and mechanical properties and aging properties of the resulting products. It also has the advantages of easy dispersion, no blooming and slight discoloration of the products. It is a commonly used vulcanization accelerator in the rubber processing industry. Mainly used in the manufacture of tires, hoses, rubber shoes, conveyor belts and other industrial rubber products. However, the accelerator MBS will release nitrosamines during the processing. In addition to causing cancer, it is also harmful to the human liver, kidneys, skin and eyes. It is even more harmful when used in tire factories. European and American countries have legislated it as early as the 20th century. Limits the application of 2-benzothiazolyl-N-morpholinyl sulfide (accelerator MBS).

Because the accelerator MBS is highly toxic and is a hazardous chemical product, national policies encourage the development of alternative products. Some tire and other rubber product manufacturers have begun to use accelerator NS to replace accelerator MBS, causing the downstream demand for accelerator MBS to continue to decline. According to the“China Accelerator MBS Industry Market Monitoring and Future Development Prospects Research Report 2022-2026” released by the Industrial Research Center, In 2021, China’s demand for accelerator MBS will be 8,200 tons, a year-on-year decrease of 2.8%.

With the development of alternative products such as accelerator NS, the market space for accelerator MBS has gradually shrunk, and the development prospects are unclear. Some companies have found it difficult to survive. They may transform and launch production lines for accelerator NS and other substitutes that have relatively environmentally friendly prospects, or turn to Southeast Asian market. The market supply and demand of my country’s accelerator MBS industry are decreasing simultaneously, market competition is relatively relaxed, and market concentration is high. The major companies with large production scales include Weilin New Material Technology Co., Ltd., Henan Kailun Chemical Co., Ltd., Shandong Shang Shun Chemical Co., Ltd., Jincheng Tiancheng Science and Technology Co., Ltd., etc.

Industry analysts said that China, as an important producer and consumer of rubber additives in the world, has a strong influence in the field of rubber additives, including accelerator MBS. The rubber additive market has strong competitiveness. In recent years, due to China’s inclusion of it as a phased-out production device and restricted use of rubber accelerators, Chinese accelerator MBS production enterprises and production capacity have decreased. In addition, the Sino-US trade dispute and India’s additional “anti-dumping” charges on Chinese rubber accelerators Tax” has impacted China’s accelerator MBS industry to a certain extent.

Under the influence of policy control, declining market demand, and growing demand for substitutes, companies in my country’s accelerator MBS industry will further adjust their product structure, reduce or stop the production of accelerator MBS, and some companies will pay more attention to the Southeast Asian market; at the same time, Declining market demand may result in no new companies entering the accelerator MBS industry. Therefore, in the future, the number of competitive entities in my country’s accelerator MBS industry may gradually decrease, and the competitive market will gradually shift to the development of substitutes.
