What is silicone antifoam defoamers?

Defoaming agents, as the name suggests, can eliminate foam produced during production or due to product requirements. As for defoaming agents, the types used will vary depending on the properties of the foam. Today we will briefly talk about silicone defoamer.

Silicone-antifoam defoamer is high in durability even under vigorous agitation or under alkaline conditions. Silicone Defoamers include hydrophobic silica diffused in silicone oil. Silicone oil has a lower surface tension that allows it to rapidly spread gas-liquid and facilitates the weakening of foam films and penetration of bubble walls.

Silicone defoamer can not only effectively break the unwanted foam that has been existing foam, but also can significantly inhibit the foam and prevent the formation of foam. It is used in a small amount, as long as one-millionth (1ppm) of the weight of the foaming medium is added, it can produce a defoaming effect.

Application:

Silicone defoamer not only has a good effect to control foam, but also has the characteristics of low dosage, good chemical inertia and can play a role under harsh conditions. As a supplier of defoaming agents, we can provide you with more solutions if you have needs.
