Antifoam and Defoaming Agents

J & W Whewell produce a wide range of formulated antifoam and defoaming agents including silicone and non-silicone types designed to prevent foam in a variety of applications.  Products may be modified for individual customers to solve specific foaming problems.

The choice of antifoam usually depends on the type of substance causing the foam, physical condition such as temperature, the length of time the antifoam is required to control foam and the compatibility the antifoam in the system.  In general, silicone based products are suitable for controlling foam in systems containing high levels of synthetic surface active agents while organic based products may be more effective at controlling foam caused by polymeric foam stabilisers such as proteins and starches.
