Foam can play havoc with your process.
Vessels overflow, raising maintenance costs. Capacity is lost, making
production runs less efficient. Food processing times increases.
Productivity decreases. And larger, more expensive equipment may be required to
compensate for the foam. Silicone foam control agents from Dow Corning have
been designed to safely and efficiently eliminate problem foam in food
processing applications. Eliminating process foam can increase your
productivity, reduce your production costs and, consequently, save your
money.
How to select the right agent for your application?
There are many factors to consider when selecting a foam control agent.
Factors such as temperature, regulatory requirements and the composition of the
foaming system need to be considered. This guide
(Excel format size = 50 KB) has taken many of these factors into
consideration and will help you select appropriate foam control agent products
for initial testing and final use.

In foam control, silicone has the advantage.
Silicone foam control agents from Dow Corning consistently out-perform their
nonsilicone counterparts in terms of versatility, strength, effectiveness,
safety and economy. We help you determine the concentration
of silicone antifoam (PDF size = 56 KB) to use in your application.
How silicone foam control agents work.
Foam is comprised of bubbles. Silicone foam control agents disperse rapidly
through the liquid film that makes up the bubble wall. Because silicone has
much lower surface tension (21 dynes/cm) than most fluids, it reduces the
surface tension film. The bubbles collapses, and the foam disappear. Silicone
foam control agents come in three basics types:
-
Fluids - Essentially inert, low-toxicity liquids available in a wide
range. Best suited for controlling foam in nonaqueous system.
-
Compounds - Silicone fluids containing a suspension of finely
powdered silica to enhance their defoaming efficiency. Primarily used for
combating foam in aqueous systems; may be used in nonaqueous system as
well.
-
Emulsions - Emulsified compounds. For applications in which
water is the predominate phase of the foam.
