Superabsorbent polymers (SAP) (also called slush powder) are
polymers that can absorb and retain extremely large amounts of a
liquid relative to their own mass. Water absorbing polymers, which
are classified as Hydrogels when cross-linked, absorb aqueous
solutions through hydrogen bonding with water molecules. A SAP's
ability to absorb water is a factor of the ionic concentration of
the aqueous solution. In deionized and distilled water, a SAP may
absorb **0 times its weight (from *0–*0 times its own volume) and
can become up to *9.9% liquid, but when put into a 0.9% saline
solution, the absorbency drops to maybe *0 times its weight. The
presence of valence cations in the solution will impede the
polymer's ability to bond with the water molecule.
The total absorbency and swelling capacity are controlled by the
type and degree of cross-linkers used to make the gel. Low density
cross-linked SAP generally have a higher absorbent capacity and
swell to a larger degree. These types of SAPs also have a softer
and more sticky gel formation. High cross-link density polymers
exhibit lower absorbent capacity and swell, but the gel strength is
firmer and can maintain particle shape even under modest
pressure.
The largest use of SAP is found in personal disposable hygiene
products, such as baby diapers, adult protective underwear and
sanitary napkins. SAP was discontinued from use in tampons due to
***0s concern over a link with toxic shock syndrome. SAP is also
used for blocking water penetration in underground power or
communications cable, horticultural water retention agents, control
of spill and waste aqueous fluid, artificial snow for motion
picture and stage production.
