defoamer polyether

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 Use And Storage

  • Addition: According to different use systems, the addition amount of defoamer can be 0.001%-0.003%, and the addition amount is determined according to the specific situation.

  • Packing: This product is packed in 25 or 200KG plastic barrels, and can also be packed according to user requirements.

  • Storage: Sealed and stored in a cool, ventilated and dry place indoors. Containers should be tightly sealed after use. The shelf life is 12 months at around 25°C.

  • Transportation: This product should be sealed well during transportation to prevent moisture, strong alkali, strong acid and rainwater and other impurities.

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.
