my country’s insoluble sulfur production has grown steadily, with East China accounting for the largest share of production

Insoluble sulfur, abbreviated as IS, is an elastic sulfur with an amorphous chain structure formed by heating sulfur to boiling, immersing it in cold water and rapidly cooling it. The molecular formula of insoluble sulfur is Su. It appears as a non-toxic, flammable yellow powder under normal temperature and pressure, and can be stored in the air for a long time without being damaged. After years of development, the preparation process of insoluble sulfur has been basically perfected and can be roughly divided into radiation method, melting method, vaporization method, etc. Among them, the vaporization method has become the mainstream process for producing insoluble sulfur in my country due to its advantages of good stability and high product yield.

Insoluble sulfur is mainly used in the production of radial tires, rubber products, antibiotics, pharmaceutical additives and other products, and is widely used in rubber products, tires, medicine and other fields. Among them, radial tires have become the largest application area of ​​insoluble sulfur.

In recent years, my country’s automobile market has gradually developed towards high quality and high performance. Radial tires have been widely used in the automobile market due to their advantages such as high safety, low rolling resistance and long service life. As the penetration rate of the radial tire market gradually increases, the market demand for insoluble sulfur increases accordingly. In addition, insoluble sulfur can also be used as an important vulcanization cross-linking agent, and is mostly used in the production of rubber products such as rubber rollers, oil seals, cables, and rubber shoes. Overall, my country’s insoluble sulfur market demand is relatively huge.

According to the “my country Insoluble Sulfur Industry Market Monitoring and Future Development Prospects Research Report 2023-2027” released by the Industrial Research Center, With the continuous development of China’s radial tire and rubber product markets, the market demand for insoluble sulfur has gradually increased, the production scale of enterprises has gradually expanded, and the output of insoluble sulfur has grown steadily. From 2016 to 2022, my country’s insoluble sulfur production increased from 77,500 tons to 128,300 tons, with an average annual compound growth rate of 8.76%.

At present, my country’s insoluble sulfur production areas are mainly distributed in Southwest China, East China, North China and other regions. Among them, East China has become the region with the largest production of insoluble sulfur in my country, accounting for 75.51% of the total.

The largest insoluble sulfur companies in my country mainly include Hongtai Rubber, Yanggu Huatai, Huasheng Rubber, Shangshun Chemical, Hengxingyuan Chemical, Kailun Chemical, etc. With the rapid development of my country’s market, the speed of corporate mergers and acquisitions in the insoluble sulfur industry has accelerated, and some companies with smaller production scales have been gradually eliminated. In the future, the concentration of my country’s insoluble sulfur market is expected to increase.

Industry analysts said that in recent years, my country’s insoluble sulfur industry has developed rapidly, but there are still some problems in the industry, such as production The technology is relatively backward, product quality is uneven, and production costs are high. In order to solve these problems, my country’s insoluble sulfur companies need to actively promote advanced technology research and development and optimize related production technologies to improve the quality of insoluble sulfur products.
