Polyether defoamer is a nonionic surfactant celebrated for its exceptional defoaming and antifoaming capabilities. This substance is characterized by its non-toxic nature, limited solubility in water, and ready solubility in organic solvents. It can be utilized either on its own or as part of an emulsion.
Commonly employed types of polyether defoamers include GPE, PPE, GP defoamers, and others. Developed by Jufu Chemical Co., Ltd., polyether defoamers tailored for various industrial applications exhibit impressive antifoaming performance. Particularly noteworthy is their ability to maintain highly effective antifoaming results at lower concentrations, making them a widely adopted solution.

Polyether Defoamer FAQs
How do polyether defoamers work?
Polyether defoamers work by spreading across the surface of the foam, causing the bubbles to coalesce and collapse. This is achieved by the defoamer's ability to lower the surface tension of the liquid, making it easier for bubbles to merge and dissipate.
In which industries are polyether defoamers commonly used?
Paints and coatings
Pulp and paper
Water treatment
Food processing
Textile manufacturing
Chemical production
Oil and gas
What are the benefits of using polyether defoamers?
Effective foam control
Improved process efficiency
Enhanced product quality
Reduced risk of equipment damage due to foam overflow
Cost savings due to reduced downtime and maintenance
Can polyether defoamers be used in both aqueous and non-aqueous systems?
Yes, polyether defoamers are versatile and can be used in both aqueous (water-based) and non-aqueous (solvent-based) systems, making them suitable for a wide range of applications.
How do I choose the right polyether defoamer for my application?
Type of foam (e.g., stable or transient)
Process conditions (e.g., temperature, pH)
Compatibility with the system
Regulatory requirements
Consulting with a defoamer manufacturer or supplier can help in selecting the most suitable product.
What should I do if the defoamer does not perform as expected?
Verify the correct dosage and application method
Check for compatibility with the process fluid
Consult with the supplier for technical support and possible formulation adjustments
Consider conducting trials with different defoamers to find the most effective one for your specific application
Can polyether defoamers be used in combination with other additives?
Yes, polyether defoamers can often be used in combination with other additives, such as thickeners, dispersants, and surfactants. However, it is important to test the compatibility and effectiveness of the combined additives in your specific application.
