A defoamer or an anti-foaming agent is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. A defoamer is normally used in industrial processes to increase speed and reduce other problems. It addresses both problems with surface foam and entrained or entrapped air.
- Lower surface tension, compared to organic antifoams
- Insoluble in most systems
- Tends to react less with process ingredients
- Persistence – generally performs longer
- Can cost less to use due to its effectiveness and persistence at low use levels
- Formulated using non ionic surfactants and functional additives, these antifoams are widely used in biotechnology, water treatment applications for easy flow of water through the membrane filter without leaving a layer of film on it.
