Differences between silicone defoamer and polyether defoamer
Silicone defoamer and polyether defoamer are two main branch products of defoamer, which can be used to solve various foam problems. What is the difference between organic silicone defoamer and polyether defoamer?
Organic silicone antifoam and polyether defoamer are named after the main components they use. The differences between them include different components, different foaming systems that can be used, and different use effects.
Organosilicon defoamer is generally polymerized with organic silicone oil, emulsifier and other additives. Because of the organic silicone composition used, the silicone antifoam can be used in both water-based systems and oil-based systems, with a wide range of applications. The antifoaming agent made of organic silicon has the characteristics of non-toxic, rapid antifoaming, no irritating smell, no side effects, etc.
Polyether defoamer is made of polyether and other additives, which is often used in water-based foaming system. In terms of application effect, polyether defoamer itself has not very outstanding foam breaking ability, but polyether defoamer has strong foam inhibiting ability. While the defoaming and antifoaming capabilities of silicone defoamers are relatively balanced, it should be noted that silicone defoamers are prone to problems in the emulsification process, which will affect their performance.
In general, silicone antifoam is suitable for water-based and oil-based foaming systems, and its defoaming and antifoaming capabilities are relatively good. However, it is necessary to solve the problems arising in the emulsification process, otherwise the use effect will not be good. Polyether defoamer is generally only applicable to water-based systems. Because its defoaming ability is different from that of foam inhibition, polyether defoamer is suitable to be added before foam production to directly inhibit the production of foam.
