About Nafion R-1000 Precursor Beads

Brand: Chemours
Product Code: 72500302

Chemours (formerlyDuPont) Resins are perfluorinated polymers used to manufacture ion-exchangemembranes, catalysts, and related materials. It is a copolymer of tetrafluoroethyleneand perfluoro-3,6-dioxa-4-methyl-7-octenesulfonyl fluoride. This thermoplasticpolymer must be hydrolyzed to convert it to a form suitable for use inion-exchange applications.

Nafion R-1000 Technical Specifications:

Bead size: 7-9 mesh(3mm x 4mm)
Bulk density (g/cc): 1.25
Ion exchange capacity (meq/g)*: 1.0 (after hydrolysis)

FAQ's of Nafion R-1000 Precursor Beads:

Q: How are Nafion R-1000 Precursor Beads typically used in membrane production?

A: These beads are primarily used as a precursor for manufacturing Nafion membranes and films, typically through extrusion or casting processes. Their chemical stability and controlled particle size help ensure uniformity and reliability during production.

Q: What benefits do precursor beads in sulfonyl fluoride form offer compared to ion-exchanged forms?

A: The sulfonyl fluoride precursor form allows customization of the final ionic properties during membrane fabrication, offering flexibility for specific research or industrial ion-exchange applications. It also contributes to the high chemical purity essential for membrane integrity and function.

Q: When should Nafion R-1000 Precursor Beads be processed to achieve optimal quality membranes?

A: Processing is typically performed when beads are freshly obtained and stored under recommended conditions, as their stable shelf life and low moisture absorption help preserve chemical properties. High-temperature operations ( 260C) are recommended for best results.

Q: Where in the United States can Nafion R-1000 Precursor Beads be purchased?

A: Nafion R-1000 Precursor Beads are available through various distributors, manufacturers, suppliers, retailers, and traders across the United States. Buyers should seek reputable sources to ensure product authenticity and proper packaging.

Q: What process is involved in converting these precursor beads into functional membranes?

A: After extrusion or casting of the beads into films or membranes, a chemical conversion step exchanges the sulfonyl fluoride groups for desired ionic forms, enabling ion-exchange capabilities. These steps result in robust, functional Nafion membranes.

Q: How does the packaging help maintain the quality of Nafion R-1000 Beads?

A: Packaged in sealed bottles or bags, the beads are protected from moisture and contamination, which helps retain high purity and stable properties during storage and transportation.

Q: What is the advantage of the product's high mechanical hardness and density?

A: Their high mechanical strength and density (2.1 g/cm3) ensure that the beads can endure rigorous processing while maintaining consistent dimensional stability, improving manufacturing yield and membrane durability.
