What are the applications of silicone defoamer?

Silicone Defoamers are derived from silicone polymers and work by destabilizing the foam structure and preventing its formation. Silicone antifoams are typically stabilized as water-based emulsions that are strong at low concentrations, chemically inert, and able to quickly diffuse into the foam film. Because of these characteristics, it is very popular among people’s choices. It’s widely used in many industrial applications to enable improved foam control in chemical processing.

1. Food processing

Silicone defoamers are widely used in direct or indirect food contact applications at all stages of the industrial process. From large factories and restaurants to home cooking, food packaging and labeling, silicone can be found everywhere. Silicone has the advantages of easy use, safe operation, no odor, and does not affect food properties, giving it unparalleled advantages in meeting various needs of food processing. They are used in a variety of food and beverage applications to defoam or eliminate existing foam during production.

Foaming issues in food and beverage processing applications can negatively impact efficiency, productivity and costs. Silicone antifoams, or defoamers, are used as processing aids and are designed to safely and effectively reduce foam problems under a variety of conditions encountered in food and beverage processing. Whether added purely in liquid or powder form, or mixed into other compounds or emulsions, silicone defoamer is more effective than organic defoamer.

① Food processing: It can effectively defoam in food processing. It is generally used in the processing of water-soluble foods. It has stable performance and good defoaming effect.

② Sugar industry: Foam will be generated during the honey sugar making process, and defoaming agents are needed for defoaming.

③ Fermentation industry: Grape juice will produce gas and foam during the fermentation process, which will affect normal fermentation. Defoaming agents can effectively defoam and ensure the quality of wine production.

2. Textiles and Leather

In the textile process, textile mills pay special attention to the performance of defoaming agents. The textile industry has strict requirements for defoaming agents, such as the viscosity should not be too high, it is easy to use, the amount of addition is easy to control, it is economical, low cost, and it defoaming is fast. The defoaming effect is long-lasting. Good dispersion, no discoloration, no silicon spots, safe and non-toxic, meets environmental protection requirements, etc.

A printing and dyeing auxiliary company produced a variety of self-produced auxiliary products andrequired defoaming agents with the following characterizations: easy to dilute and compound, has a long shelf life, and is cost-effective. Our silicone defoamer solves the problem of compounding with auxiliaries and provides technical support.

Traders of dyeing chemical raw materials, most of whom have mature users, need defoaming agents that are cost-effective, have stable product quality, and provide technical support.

Practice has proved that defoaming agents for textile printing and dyeing should have: rapid defoaming, long-lasting foam suppression, high cost-effectiveness; good dispersion, high temperature resistance, acid and alkali resistance, electrolyte resistance, shear resistance, and compatibility with various dyeing agents; safe, non-toxic, meets environmental requirements; stable quality, appropriate viscosity and concentration, easy to use and dilute; provide timely and effective technical support.

3. Pulp and paper

As a new type of defoaming agent, active silicone defoaming agent has received widespread attention in the papermaking industry. The defoaming principle is that when the defoaming agent with very low surface tension enters the directional bubble film, it destroys the directional bubble film. Mechanical balance can be achieved to achieve foam breaking and control.

Silicone defoaming agents have become indispensable additives across a wide range of industries, offering effective foam control solutions that contribute to improved efficiency, product quality, and regulatory compliance.
