Superabsorbent polymers are sodium polyacrylate-based polymers that are engineered with high affinity for liquid absorption and can retain extremely large amounts of water relative to its own mass. SAPs are used in a variety of consumer and industrial applications, such as gel packs, hot and cool packs, absorbent and incontinence pads, baby diapers, waste disposal, and agriculture applications.

Superabsorbent polymers (SAPs) are the best solution nowadays for solidifying aqueous liquid wastes, mineral slurries, and sludge streams. SAPs are extremely fast and absorb multiple times their weight with minimal volume expansion, which saves time and space during their application.
