• Figure 2: Pressure Drop (Temperature = 10–60°C)

Product Stewardship and Safety

DuPont emphasizes product stewardship, assessing health, safety, and environmental information. Users are encouraged to review manufacturing processes and applications to ensure safe use. Consult Safety Data Sheets prior to use.

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