AmberLite FPA42 Cl

Summary

Product identification

• Product Name: AMBERLITE™ FPA42 Cl Ion Exchange Resin
• Description: Food-grade, Gel, Strong Base Anion Exchange Resin
• Manufacturer: DuPont™
• Form Number: 45-D00753-en, Rev. 2
• Date: September 2019

Description

AMBERLITE™ FPA42 Cl is a high-capacity, uniform particle size, gel, Type I strong base anion exchanger. It is intended for general demineralization and deashing in applications with low risk of fouling from colored bodies and organics. Its particle size uniformity is optimized for mixed-bed applications. It can be used as a direct substitute for conventional gel anion exchange resins in new and existing demineralizers.

Applications

• Sweetener deashing
• Demineralization

Hydraulic Characteristics

Estimated bed expansion as a function of backwash flowrate and temperature is shown in Figure 1. Estimated pressure drop (in water) as a function of service flowrate and temperature is shown in Figure 2. These pressure drop expectations are valid at the start of the service run with clean water and a well-classified bed.

• Temperature for Backwash Expansion Figure: 5 – 40°C (41 – 104°F)
• Temperature for Pressure Drop Figure: 5 – 60°C (41 – 140°F)

Product Stewardship

DuPont is concerned with the safety, health, and environmental impact of its products. Customers are encouraged to review their manufacturing processes and applications of DuPont products to ensure safe and appropriate use.

Customer Notice:

• Warning: Oxidizing agents such as nitric acid can attack organic ion exchange resins under certain conditions, potentially leading to degradation or violent reactions. Consult knowledgeable sources before using strong oxidizing agents.
