As a highly efficient silane coupling agent, triethoxysilane (TES) industry has huge room for development

​​​​ Triethoxysilane (TES) is a colorless and transparent liquid with the molecular formula C6H16O3Si. It is easily soluble in ethanol and acetone, but insoluble in water. As a subdivided product of alkoxysilane, triethoxysilane has a wide range of uses. It is an important raw material for the synthesis of silane coupling agents and silicone intermediates, and can also be used as optical fiber materials.

The upstream of the triethoxysilane industry chain supplies raw materials, including trichlorosilane, absolute ethanol, silicon powder, triethyl orthoformate, trimethylethoxysilane, etc. Trichlorosilane is the core raw material for the preparation of triethoxysilane and accounts for the main production cost. Trichlorosilane, also known as trichlorosilane, is widely used in the photovoltaic field. Driven by market demand, my country’s trichlorosilane production has shown a rapid growth trend, reaching 437,000 tons in 2021, a year-on-year increase of 25.6%. The advantages of raw materials provide favorable conditions for the development of my country’s triethoxysilane industry.

The midstream of the triethoxysilane industrial chain is product preparation. Its main preparation methods include direct synthesis, alcoholysis, transesterification, etc. Direct synthesis methods include dry methods and wet methods. This method has shortcomings such as low conversion rate and high energy consumption, and is not suitable for large-scale production. The alcoholysis method is also called the esterification method, which refers to the reaction of trichlorosilane with absolute ethanol. Triethoxysilane is prepared through alcoholysis. This method is the mainstream preparation method of triethoxysilane. However, a large amount of hydrogen chloride is easily generated during the production process, and it needs to be recycled and processed in a centralized manner to avoid environmental pollution.

According to the “2022-2027 China Triethoxysilane (TES) Industry Market In-depth Research and Development Prospects Forecast Report span>》 shows that the downstream of the triethoxysilane industry chain is the application field, including silane coupling agents, optical fiber materials, etc., and sealants, photovoltaics, surface treatment agents, semiconductors, etc. are its end markets. Silane coupling agents are the mainstream functional silane products, accounting for 80.0% of the market. In 2021, my country’s silane coupling agent output reached 216,000 tons, a year-on-year increase of 16.7%. Driven by downstream demand, my country’s triethoxysilane market is expected to further expand.

my country’s triethoxysilane industry started early, with a large number of production companies and fierce market competition. Jiangxi Chenguang New Materials Co., Ltd., Hesheng Silicon Industry Co., Ltd., and Jiangxi Hongbai New Materials Co., Ltd. are the leading triethoxysilane companies in my country. Chenguang New Materials focuses on the research and development, production and sales of functional silanes. According to the company’s financial report, the company achieved revenue of 1.70 billion yuan in 2021, a year-on-year increase of 127.5%.

Industry analysts said that triethoxysilane, as a highly efficient silane coupling agent, is widely used in many fields. Driven by market demand , the industry development space continues to expand. my country’s triethoxysilane industry started early. Driven by positive factors such as technological innovation, industry concentration continues to increase. Chenguang New Materials is the largest triethoxysilane manufacturer in my country.
