The difference between silicone defoamer, polyether defoamer and polyether modified silicone oil defoamer
Silicone defoamer, polyether defoamer and polyether modified silicone oil defoamer are three different types of defoamer, and they have some differences in composition and performance. Here are their main differences:
Element:
1.Silicone defoamer: Silicone defoamer is based on organic silicon compounds. These compounds usually contain silicone structures, such as polysiloxanes, silicone oils, etc.
2.Polyether defoamer: Polyether defoamer is mainly composed of polymeric ether compounds, such as polyethylene glycol (PEG) and polypropylene glycol (PPG).
3.Polyether modified silicone oil defoamer: Polyether modified silicone oil defoamer is a mixture composed of polyether compounds and organic silicon compounds (silicone oil).
performance:
1.Silicone defoamer: Silicone defoamer has good defoaming performance and high temperature resistance. They are mainly used for defoaming under high temperature conditions, such as in plastic processing, coatings, oil field operations, etc.
2.Polyether defoamer: Polyether defoamer has high defoaming effect and surface active properties. They are often used for defoaming liquid systems, such as water-based coatings, detergents, food processing, etc.
3.Polyether modified silicone oil defoamer: Polyether modified silicone oil defoamer combines the characteristics of polyether and silicone, and has high high temperature resistance and defoaming effect. They are widely used in various industrial fields such as building materials, cosmetics, textiles, etc.
In general, silicone defoaming agents are suitable for defoaming under high temperature conditions, polyether defoaming agents are suitable for defoaming in liquid systems, and polyether modified silicone oil defoaming agents combine the characteristics of both. It has good defoaming effect under high temperature and liquid system. The selection of a suitable defoamer should be determined based on specific application scenarios and requirements.
