Sodium polyacrylate Description:

Sodium polyacrylate also known as waterlock, is a sodium salt of polyacrylic acid with the chemical formula [−CH2−CH(CO2Na)−]n

and has broad applications in consumer products.[1] This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 timesits mass in water. Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain.

Sodium polyacrylate is a chemical polymer made up of chains of acrylate compounds. It contains sodium, which gives it the ability to absorb large amounts of water. Sodium polyacrylate is also classified as an anionic polyelectrolyte.


Sodium polyacrylate advantage:

1.Water save up to 90%,incease production by 25%-40%(Reduce the frequency of irrigation)

2.Good water-absorbing ability(300-1500 times of desalted water)

3.PH value is about 6.0-8.0. Prevent soil salinization and alkalization.

4.Promote the growth of the root system and make the root system flourish more

5.The product is abundant in potassic salt and ferric salt, and is nutrient to the soil.

6.Harmless to humans and nature. Non-toxic. 100% biodegradable. Suitable for cultivation of agriculture.

7.Increase output & profits obviously. It can save the fertilizer and pesticide.Improve the usage rate of the fertilizer and pesticide.  


Sodium polyacrylate Usage:

Sodium polyacrylate is the production of baby diapers, adult diapers, sanitary napkins and other main components of personal care products. In addition to high water absorbent resin can absorb water, fertilizers, pesticides, and slow release in order to increase the efficiency and efficacy, so it can be widely used in agriculture and forestry, water etc.
