Prio silicone polyether defoamer, specially designed for harsh operating conditions.

Silicone-polyether defoamers are also known as polyether-modified silicone defoamers. It is one of the leading antifoaming products currently used in industrial applications, boasting superior performance and an exceptionally broad range of applications. It ingeniously combines… Silicone The low surface tension and high hydrophobicity of (polydimethylsiloxane), together with… Polyether Its hydrophilicity and compatibility thereby overcome the drawbacks of conventional silicone‑based defoamers, which tend to cause oil floating, and of traditional polyether‑based defoamers, which exhibit poor high‑temperature stability.

🌟 Key Features: Why is it a “versatile all-rounder”?

Extremely low surface tension
- The silicone oil component imparts extremely low surface tension, enabling it to rapidly spread across the foam film and instantly destabilize the foam. Extremely fast defoaming and foam-breaking speed. 。
Excellent compatibility (non-oily)
- By modifying the polyether chain segments, the longstanding issues of conventional silicone oils—namely, easy phase separation and oil floating (forming oily patches on the liquid surface)—have been effectively addressed. It can be uniformly dispersed throughout the system, It will not affect the quality of subsequent processes, such as dyeing, coating, or printing. 。
Exceptional thermal and chemical stability, resistant to both high temperatures and acidic/alkaline environments.
- It maintains stable defoaming performance even under high-temperature conditions (up to 100°C or higher) and in the presence of strong acids, strong bases, and high shear forces, without emulsion breakdown or loss of efficacy.
Low dosage, high efficiency
- Typically, an addition level of only a few parts per million (ppm) is sufficient to achieve a significant defoaming effect, substantially reducing operating costs.

🏭 Silicone polyether defoamer Main application areas

Due to its excellent overall performance, polyether-modified silicone defoamers are widely used in the following industries:

Textile printing and dyeing : Used in high-temperature, high-pressure dyeing, scouring, and printing processes. The key is to avoid oil bleeding, thereby preventing color spots or oily stains on the fabric surface.
Paper industry : Used in processes such as black liquor evaporation, pulping, and coating to eliminate foam and its adverse effects on paper quality.
Water treatment : In wastewater treatment aeration tanks and recirculating cooling water systems, control the excessive foam generated by an overabundance of surfactants.
Fermentation industry : During the fermentation of antibiotics, amino acids, and enzyme preparations, controlling foam overflow helps improve tank utilization.
Coatings and Inks : Eliminate microbubbles during production and application to prevent defects such as pinholes and fish eyes in the paint film.
Cleaning agents and metalworking fluids : Suppresses foam during high-pressure spray cleaning, ensuring stable cleaning pressure.

💡 Prio Silicone polyether defoamer Product advantages

As A leader in the defoaming agent industry , the polyether-modified silicone defoamer produced by Shandong Prio has the following unique advantages:

Customized formulation : For different industries (such as papermaking white water vs. dyeing high-temperature baths), Prio’s doctoral R&D team adjusts the length of the polyether segments and the viscosity of the silicone oil to provide Exclusive formula , rather than a one-size-fits-all generic product.
High-stability process : Utilizing an advanced emulsification process, it ensures uniform emulsion particle size, with no layering or demulsification during long-term storage, resulting in an extended shelf life.
Environmental safety : The product meets multiple environmental standards, is non-toxic and odorless, and is suitable for export-oriented enterprises with stringent environmental requirements.
Technical backup : If customers encounter persistent issues such as “excessive roughness” or “shrinkage cavities” during use, Prio’s technical team can provide on-site diagnosis, adjust the dosing method, or recommend a different model to ensure smooth production.

⚠️ Silicone polyether defoamer Precautions for Use

Although this product boasts powerful performance, users should still take the following precautions:

Stir thoroughly : We recommend stirring thoroughly before use. Although it does not easily separate into layers, uniform dispersion yields better results.
Avoid overcutting. Although it is shear‑stable, prolonged operation under extremely high shear conditions may cause emulsion breakdown; therefore, we recommend adding it in batches or introducing it dropwise in a continuous manner.
Compatibility testing : Before large-scale application, it is advisable to conduct compatibility tests on a small sample to ensure there are no adverse interactions with other additives in the formulation, such as optical brighteners and softening agents.
