AmberLite HPR4200 OH

Summary

Product identification

• Product Name: AmberLite™ HPR4200 OH Ion Exchange Resin
• Product Type: Uniform Particle Size, Gel, Strong Base Anion Exchange Resin for Industrial Demineralization Applications
• Previous Product Name: DOWEX MARATHON™ 4200 OH Ion Exchange Resin

Description

AmberLite™ HPR4200 OH is a high-quality resin designed for industrial demineralization applications requiring high performance, high purity water, and cost-effective operation. It offers a balance of operating capacity and low pressure drop, while aiming to reduce regenerant and rinse water usage. The resin is compatible with various system technologies and bed configurations, including single anion beds, layered anion beds, and mixed-bed polishers. Its light color facilitates easy visual distinction from dark cation resins in mixed-bed applications after backwashing. It is suitable for quick start-up in single or mixed beds, and can be paired with AmberLite™ HPR9500 or AmberLite™ HPR9600 weak base anion resins in layered bed systems.

Applications

• Demineralization:
  • Ideal for treating water with a high percentage of silica.

Hydraulic Characteristics

• Estimated bed expansion as a function of backwash flowrate and temperature is shown in Figure 1 (Temperature: 10 – 60°C / 50 – 140°F).
• Estimated pressure drop as a function of service flowrate and temperature is shown in Figure 2 (Temperature: 10 – 60°C / 50 – 140°F). These expectations are valid at the start of the service run with clean water.

Product Stewardship

DuPont emphasizes safety, health, and environmental assessment for its products. Users are encouraged to review their manufacturing processes and applications to ensure products are used as intended and tested. Safety data sheets should be consulted prior to use.

WARNING: Oxidizing agents like nitric acid can attack organic ion exchange resins, potentially causing degradation or violent reactions. Consult knowledgeable sources before using strong oxidizing agents.
