Foam Control Agents

For many applications and industries, foam isn’t just a nuisance, it’s a problem. Excessive foaming can cause vessels to overflow, interfere with processes and packaging, and damage materials or equipment. Silicone antifoams and polyglycol foam control agents can help solve all of these challenges efficiently and effectively.

Different chemistries

Silicones are especially effective for foam control – both as antifoams that prevent foam from forming, and as defoamers that react to foam and help minimize it. Silicone foam control products are available as fluids, emulsions, compounds and powders to meet many different applications.

Polypropylene glycols (PPGs) and EO/PO copolymers are also effective foam control agents because of their low foam characteristics and inverse water solubility. These products are available in liquid form, with different molecular weights and viscosities to meet diverse needs.

Trusted performance in many industries

Although every foaming situation is unique, silicone and polyglycol foam control solutions are trusted for their proven performance as processing aids, defoamers, foam preventers and deaeration materials in various industries, including:
 
 
 

When excess foam causes your processing vessels to overflow, your maintenance costs increase. You lose capacity, reducing your production efficiency. Your processing time increases, and you may require larger, more expensive equipment to handle the foam. And even worse, your customers can have issues mixing your products with others or just adding them to water in their processing units. Then, you need a proven and reliable foam control solution.

Silicones are especially effective for foam control in closed systems such as mixers, washing tanks, distillation columns, separation units, filtration and more. The Dow products work as antifoams that prevent foam from forming, and as defoamers that react to foam and help minimize it. Silicone foam control products are available as fluids, compounds and emulsions to meet many different applications and working conditions.

Applications for the Dow Silicone antifoams are wide and diverse in (but not limited to) the production of chemicals, wastewater treatment, washing operations, agrichemicals, Oil & Gas, metal treatment, food &beverage processing, animal feed, textiles, household & industrial cleaning, car care, plastics recycling and many more.
