​ ​ ​ Silicone defoamer is a subdivided product of defoamer. It refers to an additive that uses silicone oil and silicone as the main component and can eliminate foam formed by materials during the production process. Silicone defoamers appear as white viscous emulsions and have the advantages of strong defoaming power, good chemical stability, low surface tension, and good thermal stability. They are widely used in sewage treatment, textiles, printing and dyeing, chemicals, coatings, inks, papermaking, etc. Wide range of applications.

Linear polysiloxane is the main raw material of silicone defoamer, including polydimethylsiloxane, fluorosilicone and ethylene glycol siloxane. Linear polysiloxane, also known as silicone oil, has properties such as low temperature resistance, oxidation resistance, and heat resistance. In recent years, driven by positive factors such as market demand and production technology innovation, my country’s linear polysiloxane production has continued to grow and has become one of the world’s major producing countries. The advantages of raw materials lay the foundation for the development of the silicone defoamer industry.

Polyether modified silicone defoamer, also known as self-emulsifying defoamer, is the mainstream product in the silicone defoamer market and is widely used in the fermentation industry. Polyether-modified silicone defoamer uses polyether-modified silicone as raw material. Polyether-modified silicone refers to a silicon ether copolymer made by introducing polyether segments into siloxane molecules. Polyether modified silicone defoaming agent organically combines silicone oil with polyether and has strong defoaming and foam suppression capabilities. It is expected that in the future, driven by technological progress, polyether-modified silicone defoaming agents will have broad application prospects.

Silicone defoamer has a wide range of applications, with the fermentation industry as its largest demand end, and gentamicin, erythromycin, penicillin, chloramphenicol, lysine, citric acid, etc. as its end products. In addition, silicone defoaming agents are also widely used in sewage treatment, textile, printing and dyeing and other fields. Driven by market demand, the development space of the silicone defoamer industry continues to expand. According to the “2023-2027 Silicone Defoamer Industry In-depth Market Research and Investment Strategy Suggestions Report released by the Industrial Research Center , the global silicone defoamer market size will reach US$2.9 billion in 2022, a year-on-year growth of 5.2%.

The major global manufacturers of silicone defoamer include BASF AG of Germany, DOW Chemical Company of the United States, Shin-Etsu Chemical Industry Co., Ltd. of Japan, Kemira Chemical Company of Finland, etc. The main manufacturers of silicone defoamer in my country include Hubei New Sihai Chemical, Jiangsu Sail Shinyue Defoamer, Fujian Xister Environmental Protection Materials, etc.

Industry analysts said that as a representative product of defoaming agents, silicone foam agents have a wide range of applications. As market demand continues to grow, The industry development prospects are good. Benefiting from technological upgrades and sufficient supply of raw materials, the quality and output of silicone foam agents in my country have continued to improve. It is expected that companies with the production capacity of polyether-modified silicone defoamer will occupy more market space in the future.
