The NEPEM-1000 Series Perfluorosulfonic Acid Ion Exchange Resin is a versatile material. It serves as a crucial component in various applications, such as ion exchange membranes for fuel cells, vanadium batteries, and the chlor-alkali industry. Additionally, it can be involved in the preparation of hollow fiber membranes, and is used as a super acid catalyst in organic synthesis and as a superstable ion exchanger. Its adaptability across different electrolysis apparatuses highlights its significance in electrochemical and synthetic processes.
NEPEM-1000 Series
Perfluorosulfonic Acid Ion Exchange Resin
| Properties | Index Parameters |
|---|---|
| Appearance | White powder or granular |
| Acid Capacity (meq/g) | 0.91-1.00 |
| Exchange Equivalent (EW, g/mol) | 1000-1100 |
| Specific Gravity | 1.97-2.00 |
| Decomposition Temperature (°C) | >350 |
- For determining the acid capacity or equivalent weight of the polymer, a base titration procedure is employed. Specifically, caustic soda is used to titrate and measure the equivalents of sulfonic acid groups present in the resin.
- Thermogravimetric analysis (TGA) is conducted to assess the decomposition temperature. The polymer sample is placed within a furnace and heated from room temperature to 600 °C, with a controlled heating rate of 10 °C per minute.
