About sodium polyacrylate

As an amazing absorption material, sodium polyacrylate has hundreds of uses in our life. And there’re huge differences among them in the absorption, absorbent rate, water gel strength, degradation time, etc.

So, it’s kind of necessary to know sodium polyacrylate before purchase.

Uses with important indicators

1. Hygiene products

Sodium polyacrylate can be used in many hygiene products as a efficient liquid absorbent material. These hygiene products include paper diapers, sanitary towel, nursing pad, etc.

important indicators:

  • Absorbent rate;
  • Absorption under pressure and retention capacity after centrifugation;
  • Liquid Permeability;
  • Residual Monomer.

2. Waterproof tape of cable

As sodium polyacrylate gel can block water, it could be the functional material in the waterproof tape of cables.

important indicators:

  • Expansion height;
  • Granular size.

3. Ice bag/pack

With the high specific heat & spill-resistant character, sodium polyacrylate could be the thermal insulation material.

important indicators:

  • Price;
  • Granular size.

4. Inflatable sandbag

Different from traditional sanbag, inflatable sandbag (sodium polyacrylate inside) has so many advantages:

1. Transport. Lightweight before they’re used, thousands inflatable bags can be quickly transported in a van.

2. Storage. Inflatable bags can be vacuumed-packed. So they can be stored in small depots for a long time.

3. Use. Compare with traditional sandbag, inflatable bags is easier to carry & pile up.

important indicators:

  1. Absorbent rate;
  2. The photolysis resistance.

5. Leaking stoppage / Spilling treatment

Industrial grade sodium polyacrylate is cheap and can absorb plenty liquid in few minutes. And the solid waste is much easier to treatment than liquid one.

important indicators:

  1. Price;
  2. Coagulation time.
