*This article is about hydrogel powder, sodium polyacrylate, superabsorbent polymer.
Hydrogel powder: sodium polyacrylate
Sodium polyacrylate, as a type of superabsorbent polymers, can absorbent plenty water quickly and turn to water gel.
Sodium polyacrylate is safety material, it’s non-toxic, harmless, and has the character of natural degradation.
Therefore, it’s mainly application is the absorbent material in paper diaper. Actually sodium polyacrylate is widely used in every aspects of people’s life.
|Appearance||white granule / transparent gel (before/after absorbing water)|
|Main applications||absorbing, blocking liquid with expanding|
|Common test items||absorption, absorbent rate, liquid permeability, residual monomer (as AA), particle size distribution.|
Such as ice pack, fragrance carrier, water beads, growing toys and so on.
Such as paper diaper, sanitary napkin, nursing mat and so on.
waste liquid control, excreta collection and so on.
