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.
