Polyether Defoamer Non-Silicone Formula Easily Foam Control
polyether defoamers are 100% active, silicone-free non-ionic antifoaming agents for continuous foam control in fermentation bioreactors (citric acid, yeast, antibiotics, amino acids), industrial wastewater aeration basins and MBR units, pulp washing and papermaking systems, and cementitious construction materials.
Key performance characteristics:
biologically inert,no toxicity to fermentation microorganisms;
silicone-free, no oil drift, no film cratering;
broad pH tolerance (4.0–9.0 depending on grade);
and 100% active content, no water carrier, maximum defoaming efficiency per unit weight.
Product description:
Polyether Defoamer is an advanced, non-silicone foam control agent designed to deliver superior foam suppression and rapid foam-breaking performance across a wide range of industrial applications. Its unique polyether-based formulation ensures long-lasting foam control without the drawbacks associated with silicone-based defoamers, such as residue buildup or interference with downstream processes.
Key Features & Benefits:
√ Exceptional Foam Suppression
Rapidly collapses existing foam and prevents re-foaming, even under high agitation or temperature conditions.
√ Non-Silicone Formula
Avoids contamination risks in sensitive processes (e.g., food processing) and minimizes surface defects in coatings and adhesives.
√ Broad Compatibility
Works effectively in acidic, alkaline, and high-electrolyte environments, making it ideal for demanding industrial systems.
√ Thermal & Chemical Stability
Maintains performance in extreme temperatures (up to 150°C) and harsh chemical conditions.
Main performance:
(1) Fast Defoaming:
Rapid foam elimination for improved efficiency
(2) Long-Lasting Stability:
Resistant to high temperatures, acids, and alkalis
(3) Safe & Eco-Friendly:
Non-toxic, meets industry standards
(4) Wide Compatibility:
Suitable for various industrial applications
