설명

일반 설명

Sodium Polyacrylate (ASAP) is an acrylic sodium salt based hydrophilic polymer with carbonyl and sodium as major groups present in the structure. Both groups facilitate the polymeric chain with absorption potential. It can be used as a superabsorbent material as, in the presence of a liquid, the ASAP chain swells and forms a gel substance.

애플리케이션

Absorbent for aqueous-based spills. Retention and slow release aid for water.

특징 및 장점

Superabsorbent polymer. Absorbs many times its weight of aqueous fluids.
Absorbs aqueous fluids to give gels which retain fluids under stress. Polymer swells in water but does not dissolve. Amount of aqueous fluid absorbed decreases with increasing salt content.
