What Is ポリアクリル酸ナトリウム?

Sodium polyacrylate is a special hydrogel material that has transformed many industries. Renowned for its outstanding water absorption capacity, it plays a crucial role in improving water management across sectors.

This polymer can swell into a gel upon contact with water, absorbing up to 300 times its weight. Its exceptional performance is due to its unique chemical structure and crosslinked polymer network.

Chemical Composition and Structure

Sodium polyacrylate is composed of a crosslinked polymer network that includes sodium atoms. It contains repeating units of acrylic acid, which are partially neutralized with sodium hydroxide, forming sodium salt groups that attract and retain water molecules.

Manufacturing Process

The production of sodium polyacrylate involves sophisticated polymerization techniques, primarily through the polymerization of acrylic acid followed by neutralization. Different manufacturing methods lead to distinct performance profiles.

This process results in a material capable of storing vast amounts of water, making it highly effective in a variety of moisture-sensitive applications.

Key Properties of Sodium Polyacrylate

As a premier moisture control material, sodium polyacrylate offers several unique properties that make it invaluable across industries.

1. Water Absorption Capacity

• Absorbs up to 300x its weight in tap water.

• Absorbs up to 800x its weight in distilled water.

This is significantly higher than conventional absorbents such as tissue paper or cotton, which typically retain only 20 times their own weight in water.

2. Performance Characteristics

• Exceptional water retention

• Rapid absorption

• Non-toxic and safe when used properly

• Versatile for use in diverse environments

ポリアクリル酸ナトリウムの用途

Thanks to its high performance and versatility, sodium polyacrylate is used in:

• Personal hygiene products like diapers, sanitary pads, and adult incontinence items.

• 農業, where it improves soil moisture retention and reduces irrigation frequency.

• Medical applications, such as wound dressings and cold packs.

• Industrial use, including spill control and cable water-blocking.

Sodium polyacrylate is not just a material—it’s a solution. With its unmatched water absorption capabilities, environmental friendliness, and wide application range, it continues to lead innovation in moisture management across the globe. As industries strive for sustainability and efficiency, sodium polyacrylate offers a powerful tool to meet those demands.
