In all walks of life, most products have to go through a series of steps when they are manufactured. However, during the production operation, there will be too much foam that hinders the production process, so there are all kinds of defoamers. However, in the final analysis, defoamers are generally divided into two types of defoamers: silicone and non-silicone. So what is the difference between these two defoamers?

From the perspective of chemical composition, silicone defoamers are mainly made of silicone compounds, while non-silicone defoamers are made of other compounds, such as fatty acid salts, polyethers, etc. The main component of silicone defoamers is polysiloxane, which has a special chemical structure and can form a stable film on the surface of the liquid, thereby inhibiting the formation and diffusion of bubbles. Non-silicone defoamers achieve the defoaming effect by changing the surface tension of the liquid.

From the perspective of application areas, silicone defoamers are mainly used in industrial fields such as liquid detergents, coatings, paints, and foam plastics. Since silicone defoamers have excellent defoaming performance and stability, and can effectively reduce the bubble content in liquids, they are widely used in these fields. Non-silicon defoamers are mainly used in food processing, pharmaceuticals, cosmetics and other fields because they are non-toxic and harmless to the human body and will not affect the quality of the product.

Silicones emphasize the principle of universality and tend to cover the process links of various industries to the greatest extent, such as energy mining and daily cleaning. It is committed to maximizing the versatility of products. The product orientation of non-silicon defoamers is more inclined to specialization, making up for the fields that silicones cannot be applied to, such as papermaking and coating.

In summary, organic defoamers are mainly made of silicone compounds and are more suitable for industrial applications; while non-silicon defoamers are made of other compounds and are better used in food, pharmaceuticals and other fields. Both have their advantages, so before choosing a defoamer, you should determine the application scenario to achieve the best defoaming effect.
