Functional silanes are widely used in rubber processing, adhesives, composite materials, metal surface treatment and building waterproofing. A class of functional silanes, mainly used in the rubber industry; it can effectively improve the binding ability of silica fillers and rubber molecules, and can promote rubber vulcanization. At the same time, it has the functions of coupling agent and accelerator vulcanizing agent, and has become the most widely used in radial tire production. important raw material.

According to Markets and Markets data, the global functional silane market will increase from US$1.33 billion in 2015 to US$1.7 billion in 2020, with a CAGR of 5% from 2015 to 2020; among which, the strong demand for silane in the Asia-Pacific region is driving the global silane market. main factor for growth.

According to SAGSI statistics, in 2019, my country's functional silane production capacity is about 430,000 tons/year, and its output is about 279,000 tons. It is already the world's largest producer of functional silanes. SAGSI estimates that by 2023, my country's total output of functional silanes will increase. It will reach nearly 390,000 tons, and the global output will further increase to 72.3%; in 2019, the domestic sulfur-containing silane output will be 89,700 tons, accounting for 32.2% of the output, which is the largest variety of functional silane production in my country.

Considering the gradual implementation of domestic green tire regulations and the gradual maturity of the new energy vehicle market, we estimate that the annual domestic output of sulfur-containing silane is expected to reach 125,600 tons in 2023.

In addition, with the steady development of rail transit, composite materials and carbon fiber, and building waterproofing industries, the demand space for functional silane industry will be broader in the future.
