The types of defoamers

In industrial processes where foam can compromise both efficiency and product quality, defoamers serve an essential function. The advanced performance and lasting stability of modern defoamer formulations stem from their carefully engineered multi-component structures. Each functional element works in concert to deliver efficient and durable foam control.

Primary Defoaming Agents:
These are the core active ingredients—such as dimethyl silicone oil and polydimethylsiloxane—responsible for rapidly breaking existing foam bubbles and preventing new ones from forming.

Auxiliary Defoaming Agents:
Substances like fatty acid esters and phosphate esters complement the primary agents, enhancing the overall defoaming effectiveness.

Carrier Medium:
Making up the bulk of the formulation, carriers such as water or liquid hydrocarbon oils serve as the base that dissolves or disperses the other components.

Spreading or Emulsifying Agents:
Ingredients including various esters, epoxy-based polymers, and sorbitan esters ensure the defoamer spreads uniformly and acts quickly throughout the target system.
