my country is a major producer and exporter of sulfur-containing silanes, with a high degree of industry concentration.

Sulfur-containing silanes refer to functional silanes with sulfur as the main functional group. Sulfur-containing silane appears as a light yellow to light brown transparent liquid with a slight smell of ethanol. It is soluble in toluene, acetone, ethanol and other solvents, but insoluble in water. Sulfur-containing silanes have the advantages of good chemical stability and durability. They can be used as accelerators, coupling agents and vulcanizing agents. They are widely used in synthetic rubber, refractory materials, shoe materials, mechanical casting and other fields.

Based on different structural compositions, sulfur-containing silanes can be divided into two types: mercapto-type sulfur-containing silanes and polysulfide-type sulfur-containing silanes. Mercapto-type sulfur-containing silanes are also called mercapto-silanes, including γ-mercaptopropyltriethoxysilane (KH580) and γ-mercaptopropyltrimethoxysilane (KH590), etc.; polysulfide-type sulfur-containing silane is the sulfur-containing silane market Mainstream products mainly include bis(triethoxysilylpropane) disulfide, bis(triethoxysilylpropane)tetrasulfide, etc. At present, my country’s polysulfide-based sulfur-containing silanes technology is highly mature, driving its production to continue to grow.

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​… According to statistics from the Silicon Industry Green Development Alliance (SAGSI), my country’s functional silanes export volume will reach 91,000 tons in 2021, a year-on-year increase of 2.8%. Sulfur-containing silanes are the most exported functional silanes from my country, accounting for nearly 60% of the total export volume. The Netherlands, the United States, Japan and South Korea are my country’s main exporting countries.

In terms of application fields, sulfur-containing silanes are widely used in synthetic rubber, refractory materials, shoe materials, mechanical casting and other fields, among which the synthetic rubber field is the largest demand end. Sulfur-containing silanes can effectively increase the vulcanization speed of rubber, and functional silicone rubber, styrene-butadiene rubber, etc. are its end products. In recent years, the prosperity of my country’s automobile tire industry has continued to improve, driving the demand for rubber applications to continue to grow. Against this background, my country’s sulfur-containing silanes production continues to increase. According to the “2023-2028 China Sulfur-Containing Silane Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, In 2022, my country’s sulfur-containing silanes production will reach 126,000 tons, a year-on-year increase of 10.1%.

The major global manufacturers of sulfur-containing silanes include Shin-Etsu Chemical Industry Co., Ltd. of Japan (Shin-Etsu), The Dow Chemical Company of the United States (Dow), etc. my country’s sulfur-containing silane industry is highly concentrated, with major manufacturers including Hongbai New Materials, Chenguang New Materials, Jianghan New Materials, Yanggu Huatai, etc. Hongbai New Materials focuses on the research and development, production and sales of sulfur-containing silane coupling agents, and its product sales have long ranked first in my country and even the world.

Industry analysts said that as a mainstream product in the functional silane market, sulfur-containing silanes have excellent performance, wide range of uses, and good industry development prospects. . my country is a major producer and exporter of sulfur-containing silanes. Our products not only meet the needs of the local market, but are also sold overseas. In terms of market competition, my country’s sulfur-containing silane industry is highly concentrated, and local companies have a competitive advantage in the global market.
