OVERVIEW: Superabsorbent polymers (SAP) are large chain-like molecules that can absorb water up to thousands of times their own weight. Their ability to absorb is strongly related to the surface area of the polymer that is in contact with water. The surface area depends on the polymer particles size. Fine particles result in larger area than coarse particles.
