Salt-Tolerant, Water-Absorbing Polymers: AQUALIC™ CS Modified cross-linked polyacrylate
- Main Applications
Water blocking agents for civil engineering and cables, etc.
- Applications
- Functions
Basic Information
AQUALIC™ CS are salt-tolerant and water-absorbing polymers that are mainly used in civil engineering.
These polymers maintain stable water absorption even in water containing high levels of electrolytes, such as seawater.
| Appearance | White powder | |
|---|---|---|
| Absorption Amount (g/g-SAP) | Deionized Water | 100-200 |
| Normal Saline Solution (NSS)※3 | 30-40 | |
| Artificial Seawater※4 | 20-30 | |
| Calcium Chloride Aqueous Solution※5 | 10-15 | |
| Average Particle Diameter (μm) | 10-100 | |
*4: Aqueous solution of 43.0 – 48.0 mS/cm electrical conductivity containing univalent – bivalent ions
*5: 5% calcium chloride aqueous solution
Features and Properties
Excellent absorption of groundwater and seawater
The amount of water absorbed by general water-absorbing polymers decreases in seawater and other such aqueous solutions with a high saline concentration and in polyvalent metal salt aqueous solutions; however, AQUALIC™ CS polymers maintain their water-absorption amounts in such aqueous solutions.
Lineup
The table below shows key representative types of AQUALIC™ CS. Additional products are also available.
| Item Number | Features |
|---|---|
| CS 8S | Small particle diameter and high absorption amount type |
| CS 81S | Small particle diameter and low absorption amount type |
