Defoaming agents are of great importance in industrial production. They effectively improve the bubble problem in industrial production, thereby improving production efficiency and product quality.
In recent years, the defoaming agent market has grown rapidly. In 2018, the global defoaming agent market size was only US$3.2 billion. By 2022, its size had reached US$6.443 billion. It is expected to reach US$8.786 billion by 2029, with a compound annual growth rate (CAGR) of 5.16% (2023 -2029). Among them, silicone defoaming agents account for a large proportion, and their share will reach 44.85%.

Silicone defoamers offer significant advantages
1.Wide range of applications
Since silicone oil is an important component of silicone defoamer, it is insoluble in substances containing polar groups, and is not easily soluble in hydrocarbons or organic substances containing hydrocarbon groups. Therefore, silicone defoamer has a wide range of applications, including water-based systems and oil-based systems.

2. Strong plasticity
Silicone defoaming emulsion is made from silicone paste emulsified with an emulsifier, and the quality of the silicone paste is crucial to the performance of the silicone defoaming agent. The quality of silicone paste is affected by factors such as the viscosity of dimethyl silicone oil, the hydrophilicity and hydrophobicity of silica, additive addition and processing technology.
(Generally, the lower the viscosity of dimethyl silicone oil, the faster the defoaming speed, and the higher the viscosity, the better the foam suppression effect; hydrophobic silica can improve alkali resistance; high temperature and rapid stirring can make the additive Mix thoroughly to form a cross-linked body, and the foam suppression effect will be better.)


Therefore, silicone defoaming agents can adapt to different types of foaming liquids and various foaming environments.
