DuPont™ AmberLite™ HPR4200 CL High-quality Resin For Industrial Demineralization applications

1. Product Overview

DuPont™ AmberLite™ HPR4200 Cl is a uniform particle size, gel-type, strong base anion exchange resin (Type I) designed for industrial demineralization applications requiring high performance and cost-effective operation. Its balanced chemical properties and particle size provide excellent operating capacity with low pressure drop while reducing chemical regenerant and rinse water consumption. Compatible with all system technologies, it can be used in lead single or layered anion beds and mixed bed polishers, allowing users to inventory only one strong base anion resin for various demineralization needs. The light color of this resin enables easy visual distinction from dark-colored cation resins after backwash separation.

2. Applications

• Demineralization

  • Ideal for treating water with a high percentage of silica

  • Effective for removing strong and weak acids and achieving low silica leakage

• Mixed bed polishing

3. Compatible System Designs

• Mixed beds

• Packed beds

• Layered beds

• Counter-current / hold-down systems

• Co-current systems

4. Recommended Resin Pairings
