Silicone defoamer is a defoamer that consists of silicone compounds and other additives. They are commonly used to remove air bubbles and foams from liquids, especially in the chemical, petroleum, pharmaceutical and food industries.
The advantage of silicone defoamers is that they are able to eliminate various types of foam, including high and low foam, and have excellent stability and compatibility during use. They are also able to maintain good defoaming properties in the presence of surfactants, which makes them more suitable for certain applications.
