Polyether Defoamer
Product FeaturesPolyether defoamer is a highly efficient, widely applicable non-ionic surfactant whose primary function is to rapidly eliminate existing foam and effectively suppress the formation of new bubbles. It is particularly suitable for use under harsh conditions such as high temperatures and acidic or alkaline environments, and offers irreplaceable advantages in safety-critical fields like food and pharmaceuticals.

Product Benefits
- Thanks to its three core advantages—safety and non-toxicity, long-lasting defoaming performance, and no silicone residue—polyether defoamer has become the preferred choice in industries demanding high purity, such as food, pharmaceuticals, and water-based coatings.
- Its excellent chemical stability and broad temperature adaptability (some grades can withstand up to 150°C) ensure effective, long-term foam control in complex systems.
FAQ
-
What should I do if the defoaming effect is poor?
This is usually caused by insufficient dosage, uneven dispersion, or incompatibility between the defoamer and the system. It is recommended to gradually increase the dosage for stepwise testing and ensure that the addition point promotes proper dispersion.
-
Defects such as cratering and fisheye appear after addition?
This is usually caused by excessive dosage or insufficient dispersion. Reduce the dosage appropriately and extend mixing time to ensure complete dispersion.
-
What should I do if the product separates or becomes cloudy?
Store in a cool, dry place at 5°C to 35°C, avoiding freezing and high temperatures. For slight separation, simply stir until uniform; if clumping occurs or the product cannot be restored, it has deteriorated and is no longer effective.
-
Can it be stored for a long time after dilution?
No. The stability of the defoamer decreases significantly after dilution, and it should be used within 8 hours to prevent separation or loss of effectiveness.
-
How to determine the optimal dosage?
It is recommended to determine this through small-scale trials. Start with a low dosage (e.g., 10 ppm), then increase in increments of 10 ppm, observing the foam control effect until the lowest economical dosage that meets requirements is found.
