Product Description
Product Detail
Sodium polyacrylate is an anionic polyelectrolyte with negatively charged carboxylic groups in the main chain. It is a chemical polymer made up of chains of acrylate compounds containing sodium, which gives it the exceptional ability to absorb large amounts of water. This material is classified as a superabsorbent polymer (SAP).
It serves as a core material in absorbent cores, rapidly locking liquids such as urine and menstrual fluid, converting them into a soft gel to maintain a dry and comfortable surface.
