3.Synergistic enhancement technology: Multiple functional groups work cooperatively to strengthen interface disruption capability

Performance Comparison

Performance Metric	Conventional Defoamer	Polyether Ester Defoamer
Dispersion Time	>5 minutes	<1 minute
Defoaming Efficiency	60-70%	>90%
Duration of Effect	2-4 hours	8-12 hours
Viscosity Adaptability	<5000cP	>50000cP

Case Study: Foam Control in Resin Production

A specialty resin manufacturer experienced severe foaming issues during polymerization:

1.Foam overflow in reactors caused 15% yield reduction
2.Required 3-4 manual defoamer additions per batch
3.Product quality compromised by bubble defects

After implementing customized polyether ester defoamers:

1.Achieved higher efficiency with lower dosage and longer-lasting foam suppression
2.Reduced foam height from 30cm to below 5cm
3.Improved product qualification rate to 99.2%
4.Achieved annual raw material cost savings of approximately ¥600,000
