Blowing agent and defoamer are two different chemicals that have opposite functions.

Foaming Agent is a substance that creates bubbles or bubbles in a liquid. It is commonly used in the manufacture of foam plastics, detergents, foam concrete and other products. Blowing agents can increase the volume of a liquid or mixture and form a bubble structure.

In contrast, Defoamer is a substance used to control or stop the formation of bubbles or bubbles in a liquid. Defoamer is usually used in industrial processes, such as chemical production, paper making, sewage treatment and so on. Defoamer can destroy or inhibit bubbles in the liquid, thereby reducing or eliminating foam formation.

Therefore, foaming agents and defoamers have very different functions and application areas.
