Silicone antifoams are extensively
used where product or process foaming problems are
encountered. Foam is a mass of bubbles created when certain types
of gas are dispersed into a liquid and the dispersion is then
stabilized. High-strength films of liquid surround the bubbles,
forming large volumes of non-productive foam.
While the actual cause of foam is a complicated study in physical
chemistry, its existence presents serious problems in both the
operation of industrial processes and the quality of finished
products. If not controlled, foam can reduce equipment capacity and
increase processing time and expense.
Chemical defoamers have proven to be the most effective and
economical method to control foam. Silicone antifoams are used
to control foam in the manufacturing and processing of products in a
range of industries: |
