The application scenarios of defoamer are very wide, mainly in the fields of metal processing liquid, rubber latex removal, textile sizing, food fermentation, biomedicine, coatings, petrochemical, paper making, industrial cleaning, sewage treatment and so on. In recent years, due to the rapid development of downstream industries, the demand for silicone defoamer continues to rise, and in 2020, the market size of silicone defoamer in China has reached 15.84 billion yuan, an increase of 9.3%.


The main components of defoamer are active ingredient, emulsifier, carrier and emulsifying agent. The active ingredient is the core of the product, which can play the role of breaking bubbles and reducing surface tension. The second is the emulsifier, which can help disperse the active ingredients into particles, so that they can be better dispersed into oil or water and play a better anti-foaming role; The carrier occupies a large proportion in the defoamer, which mainly plays the role of supporting medium, which is beneficial to the defoaming and defoaming, and can reduce the cost. Emulsifying agent is to make the emulsifying effect better.


In terms of production, due to the rapid development of downstream industry, the demand for defoamer in China has continued to rise in recent years, driving the development of the industry. At present, the number of defoamer manufacturers is also growing. In 2019, the number of silicone defoamer manufacturers above the scale in China has reached more than 550, and the output is also rising year-on-year. In 2019, the production of silicone defoamer in China reached 152,000 tons, an increase of about 15.2%.


At present, the market demand for defoamers is mainly divided into imported and domestic, of which imported defoamers occupy an important market in China, the main brands are Dow Corning, Rhodia, Dechianxiao, BYK, Ashland, Clariant, Bluestar, Knopco, Degaussa, EFKA, Dow and so on. There are a large number of defoamer enterprises in China, but there is a gap with multinational companies in terms of production scale and quality. At present, domestic brands include Boyi and immediately, Liqi, Hengxin, Zhongfei, Seou Xinyue, Huaxing, Jinfeng, Defeng, Langjie, Sihai and so on.


As a common industrial production basic supplies, defoamer has a wide range of application scenarios, market demand continues to grow, and the industry has good development prospects. In terms of production, with the continuous improvement of technology, China's defoamer enterprises are constantly improving in terms of product types and product quality, and will be able to achieve comprehensive domestic substitution in the future.
