Applications of Sodium polyacrylate

There’re two mainly types super absorbent polymers: sodium polyacrylate and potassium polyacrylate.

Potassium polyacrylate can be mainly used in agriculture as a water-retaining agent. And sodium polyacrylate is applied to every aspect of life:

Diapers and sanitary napkins – to absorb water and lock it.

More than 90% sodium polyacrylate is used in diapers (and sanitary napkins).

With the strong absorbing ability, sodium polyacrylate can increase diaper’s absorption and keep dry.

Inflatable bags – to absorb water and increase bags’ weight.

Inflatable bags (also call sadness flood control bag, only 500g/per piece) can increase weight to 20-25kg after absorbing water.

It consists of bag and sodium polyacrylate.

Instant snow – turn to plenty white powder (like snow) when meet water.

Sodium polyacrylate type instant snow is amazing stuff which is like snow very much.

It is widely used in movie landscapes, Christmas decorations and children toys.

Water repellent taps in cable – hydrophilic expansion and insoluble in water.

Water repellent taps will prevent copper wire rust when outer layer is broken.

That’s because SAP will swell and prevent moisture into the cable inside.

Concrete Protection – increase the humidity and prevent the cracking of cement.

Throughout the life of concrete, water has central importance.

And the water gel of SAP in the concrete will increase the humidness so that prevent concrete cracking.
