What is modified polysiloxane defoamer?
Silicone-based defoamers are widely used in various industries due to their excellent performance in eliminating foam. However, traditional defoamers have some drawbacks, such as poor compatibility with certain systems and limited effectiveness at high temperatures. Modification of silicone defoamers can help overcome these limitations.
What is modified polysiloxane defoamer?
Modified polysiloxane defoamer, also known as silicone-based defoamer, is a type of defoaming agent that undergoes some chemical changes to improve its performance. The modification process involves functionalizing the traditional silicone molecule with various functional groups to enhance its compatibility, thermal stability, and foam control properties.
Advantages of modified polysiloxane defoamer:
Improved Compatibility - Modification of silicone defoamers helps to improve their compatibility with a wider range of systems. This is achieved by altering the chemical structure of the silicone molecule to make it more compatible with different substrates.
Enhanced Thermal Stability - Traditional silicone defoamers are known to lose their effectiveness at high temperatures. Modification helps to improve their thermal stability and allows them to perform better under elevated temperature conditions.
Better Foam Control - Modified defoamers offer improved foam control properties due to the introduction of new functional groups. This allows them to more effectively break down foam and improves their anti-foaming efficiency.
Modified silicone defoamers have become increasingly popular due to their improved performance over traditional defoamers. The benefits of these modified defoamers include improved compatibility, enhanced thermal stability, and better foam control. As a result, defoamer are widely used in various industries, including construction, water treatment, paper making, steel mills, oil fields, chemical industry, etc.
