Silane cross-linking agent products are widely used and market demand is gradually expanding.

Silane cross-linking agents refer to silanes containing two or more silicon functional groups, which can bridge between linear molecules, so that multiple linear molecules or micro-branched macromolecules and polymers can bond and cross-connect each other into three-dimensional A network structure that promotes or mediates the formation of covalent or ionic bonds between polymer molecular chains. According to the different condensation reaction products in one-component room temperature vulcanized rubber, silane cross-linking agents can be divided into three categories: deacidification type, ketoxime type and dealcoholization type.

Silane cross-linking agents are functional silanes. After the cross-linking agent is added to the polymer, it has better physical and mechanical properties, heat resistance, solvent resistance, etc., and can be used for silicone resin synthesis and coating modification. Among them, deacidified silicone products mainly include methyltriacetoxysilane, di-tert-butoxydiacetoxysilane, etc., which are mainly used in the fields of silicone rubber and adhesives; dealcoholized silicone products include methyl orthosilicate, Ethyl orthosilicate, etc., can be used in the fields of silicone rubber, surface treatment, coatings, etc.; the ketoxime type includes methyltributylketoneoxime-based silane, which is used in the fields of silicone rubber and adhesives, and is compared with deacidification-type products. , the ketoxime type is milder and has lower biological toxicity.

In recent years, the production technology level of my country’s silane cross-linking agent industry has been continuously improved, and product quality and performance have been greatly improved. However, compared with leading foreign companies, my country’s silane cross-linking agent products have become high-end, specialized, and new. There is still a lot of room for development. High-end silane cross-linking agent products are limited by technical barriers, and the gap with foreign countries is still obvious.

According to the “China Silane Cross-linking Agent Industry Market Monitoring and Future Development Prospects Research Report 2023-2028” released by the Industrial Research Center It shows that silane cross-linking agent is an important synthetic raw material and is used in rubber processing, plastic processing, coatings and surface treatment, adhesives and other fields. It has many downstream products and a wide range of terminal applications, and has good market growth space. In 2022, driven by the continued development of the downstream industry, China’s demand for silane cross-linking agents will reach 80,000 tons, and industry output has also shown a year-by-year growth trend driven by demand.

At this stage, there are not many companies in the domestic silane cross-linking agent industry. Some small-scale, weak, and non-environmentally friendly companies are gradually withdrawing from the market in the context of increasingly stringent environmental protection requirements. Industry concentration continues to increase, and representative companies in the industry The main ones include Hubei New Blue Sky New Materials Co., Ltd., Hangzhou Silicon Bao Chemical Co., Ltd., Hubei Jianghan New Materials Co., Ltd., Jiangxi Chenguang New Materials Co., Ltd., Zhejiang Xin’an Chemical Group Co., Ltd., etc.

Industry researchers said that in the future, as China’s rubber processing, plastic processing, adhesives, coatings and surface treatment and other fields will continue to develop , especially the expansion of industrial scale in the fields of rubber processing and plastic processing, will drive the growth of demand for silane cross-linking agents, and the market development prospects are broad. At the same time, benefiting from the good development prospects, existing companies will further expand their production capacity, and industry output will also maintain a growth trend.
