Industrial Defoamer Procurement Guide

Industrial defoamer procurement should focus on the foaming medium, process condition, compatibility and the balance between rapid defoaming and foam suppression.

Classify the foaming system

A pulp defoamer, metalworking fluid defoamer, water-based ink defoamer and oil and gas defoamer can have different compatibility requirements. Start with the process and medium.

Key comparison points

• Rapid foam knockdown
• Long-term foam suppression
• Compatibility and transparency
• pH and temperature range
• Dilution and dosing method
• Impact on final product

Sample testing recommendation

Run small-scale compatibility and dosage tests before production use. Provide test conditions to Juyou so the technical team can recommend a closer grade.
