What is Sodium Acrylate？

Sodium Acrylate is the sodium salt of acrylic acid, commonly used in the production of superabsorbent polymers. It appears as a white powder or granule and is known for its ability to absorb and retain water, forming hydrogels. It is widely used in hygiene products, coatings, wastewater treatment, and agriculture due to its excellent water retention and thickening properties.

Application

Sodium Acrylate used in the production of superabsorbent polymers for diapers and sanitary products
Functions as a thickener and viscosity modifier in paints and coatings
Sodium Acrylate Acts as a flocculant in wastewater treatment
Sodium Acrylate used in detergents and other cleaning formulations
Sodium Acrylate serves as a water-retaining agent in agricultural soil conditioners

How it works (as a polymer):

When sodium acrylate monomers are polymerized, they form a network that can swell by osmosis. 。

The presence of many sodium ions inside the polymer network creates an osmotic pressure that draws water in.

This process allows the polymer to absorb and hold large quantities of water, making it "superabsorbent".

Safety profile

Sodium Acrylate is generally safe for industrial use when handled properly. It may cause irritation to eyes, skin, and respiratory tract. Use of protective gloves, masks, and adequate ventilation is recommended. Avoid direct contact or inhalation of the powder.

Storage requirements

Keep the product in a dry, cool, and well-ventilated place
Seal container tightly after each use
Avoid exposure to moisture and direct sunlight

Transport & Packaging
