Sodium polyacrylate, industrial grade super absorbent polymer, sold at the best price

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. This super-absorbent polymer (SAP) has the ability to absorb 100 to 1000 times its 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.

What is Super Absorbent Polymer(SAP)?

SAP (Super absorbent Polymer) is a functional polymer with higher water absorption and superior water retention capability. Hence, it is employed in projects requiring: absorption of waterjetention of excess water and effectively blocking the movement of water.

The advantageous aspect of using SAP is that it is: non Toxic, non-pollutant, and harmless in every aspect.


The normal SAP is available in white granular form; its granules come in various sizes. The type of application that SAP is to be used for is the determining factor for deciding the size of granules required

e.g. Agricultural usage may require SAP of a size ranging from 5-20 mesh for trees while SAP for sewage solidification may be between 30-100 mesh.


Liquid Absorption Capability

This is one of the most vital yardstick by which we measure the quality of this product.

The test for its water absorption prowess is quite simple and straightforward;

we use 1 gm of SAP and see the absorption within a specified time.

Our tests have revealed that the amount of distilled water absorbed is between 200- 800 gm.

Liquid Absorption Capability

Liquid Absorption Capability (under pressure)

Strong liquid-absorbing and liquid-locking capabilities for certain conditions and applications; these capabilities provide a wide usage to SAP in the case of:

-Paper diapers,

-Sanitary towels and Napkins,

-Other hygiene products.

Liquid Absorption Capability (under pressure)


For Hygiene Products

With its awesome properties of liquid-absorption and locking it has finds very useful application in products prone to moisture like: diapers, sanitary napkins, nursing pads and pet pads.
