Polyether Ester Defoamer
Product FeaturesThe core advantage of polyether ester defoamer lies in combining the strengths of polyether and fatty acid esters, offering excellent water dispersibility and defoaming performance, while particularly excelling in achieving dual effects of "defoaming" and "degassing" in complex aqueous systems such as papermaking.

Product Advantages
- Synthesized through an esterification reaction between polyether and fatty acids, this product incorporates ester groups into its molecular structure, enhancing its oil affinity.
- As a result, it demonstrates superior foam suppression capability and more effective removal of fine bubbles within liquids compared to conventional polyether defoamers.
FAQ
-
What should I do if the defoaming effect is unsatisfactory?
First, check whether the dosage is insufficient; a gradient test can be conducted. Next, verify the addition point—choose the location where foam originates or in turbulent zones to ensure thorough dispersion. Also, pay attention to whether the system temperature is approaching or exceeding the cloud point (typically 15–30°C), as high temperatures may reduce the product's self-emulsifying ability in water, potentially affecting performance.
-
Why do "fish eyes" or craters appear after addition?
This may be caused by excessive addition or low system temperature (e.g., below 50°C), leading to poor dispersion. Reduce the dosage appropriately and ensure the system temperature is within the recommended range.
-
What should I do if the product separates or deteriorates?
Store in a cool, dry place at 5–35°C, protected from freezing and direct sunlight. Ester bonds may hydrolyze under strong alkaline conditions; it is recommended to prepare and use immediately under extreme operating conditions.
-
Can it be stored for a long time after dilution?
No. After dilution, the stability of polyether ester defoamer drops sharply, making it prone to separation and loss of effectiveness. It should be prepared and used immediately. If the product instructions explicitly advise against dilution, use the concentrate directly.
