Product Introduction

Industrial Sodium Polyacrylate (CAS 9003-04-7) is a highly efficient super absorbent polymer (SAP) derived from polyacrylic acid sodium salt. Known for its exceptional liquid uptake capacity and gel-forming properties, it is widely used in industrial applications such as sludge stabilization, liquid waste solidification, absorbent packaging, spill control, and water-retention systems. When in contact with aqueous liquids, the material rapidly absorbs, locks, and retains water or ionic solutions, forming a stable gel structure that enhances handling, storage, and environmental safety.

Key Product Features

• Ultra-high absorption capacity
Absorbs hundreds of times its weight in water, depending on ionic concentration.

Fast liquid uptake for efficient process handling.

• Stable gel formation
Prevents liquid re-release, leakage, and mobility.

• Chemical and thermal resistance
Suitable for diverse industrial environments.

• Customizable particle size & absorption rate
Available in fine, medium, and coarse grades.

• Eco-conscious handling benefits
Reduces contamination spread, improves disposal efficiency.

• Broad industrial compatibility
Ideal for sludge treatment, spill management, cold chain absorbents, and solidification systems.

FAQs

1. What is Sodium Polyacrylate typically used for in industrial applications?

It is used for sludge solidification, liquid waste immobilization, spill absorption, cooling gel packs, protective packaging, and water-retention systems in agriculture and construction.

2. How much liquid can this polymer absorb?

Absorption ranges from 100–800 times its weight in deionized water, with lower absorption in saline or high-ion-content environments.

3. Does the absorbed liquid leak out after swelling?

No. It forms a cross-linked gel structure that securely retains liquid and prevents release under normal handling conditions.

4. Can the product be customized?

Yes. Absorption speed, capacity, crosslink density, and particle size can be tailored to specific industrial requirements.

5. Is Sodium Polyacrylate safe to use?

It is non-toxic for industrial handling when used as directed and complies with standard chemical safety guidelines. It should not be ingested and must avoid dust inhalation.

6. What factors affect absorption performance?

Key influences include:

• ionic strength of liquid

• temperature

• pH level

• contact time

• particle surface area

7. How should the product be stored?

Store in a cool, dry, sealed container away from moisture and humidity to prevent premature swelling.

8. Is it biodegradable?

Standard sodium polyacrylate is not biodegradable, though biodegradable modified SAPs are available depending on supplier and formulation.
