Sodium Polyacrylate

Sodium Polyacrylate PAAS

[ Synonyms ]
Polyacrylic acid sodium, polyacrylic acid sodium salt,PAAS

[ Properties ]
CAS No.: 9003-04-7
Sodium polyacrylates, also known as slush powder, sodium polyacrylate powder instantly turns a sodium polyacrylate liquid into a sodium polyacrylate solid. Sodium polyacrylate is innoxious and soluble in water, polyacrylic acid sodium can be used in situations of alkaline and high concentration without scale sediment. PAAS can disperse the microcrystals or microsand of calcium carbonate, calcium phosphate and calcium sulfate. Sodium polyacrylate 96% is used as scale inhibition and dispersant for circulating cool water system, papermaking, weave, dyeing, ceramic, painting, etc.

[ Uses of Sodium Polyacrylate]
PAAS sodium polyacrylate can be used as scale inhibitor and dispersant in circulating cool water systems in power plants, iron & steel factories, chemical fertilizer plants, refineries and air conditioning systems. Dosage should be in accordance with water quality and equipment materials. When used alone, 2-15mg/L is preferred. When used as dispersant, the dosage should be determined by experiment.
[ Package & Storage ]
25kg or 200kg in plastic barrel. Storage for ten months in room shady and dry place.

PAAS Safety Considerations:

Students who have alllergies, especially allergy to disposable diapers should be an observer or recorder for the group. Sodium polyacrylate is non-toxic! However, if placed in the eye, the eye will become dry and irritated. Inhalation of the powder will also be irritating to nasal membranes. Be careful, and minimize exposure to sodium polyacrylate. Dispose of excess powder and/or gelled material in the trash. Do not put down the sink!

Polyacrylamide, a cationic polyacrylamide charged polymer used in straight-chain form or can be co-polymerized with acrylic acid and other monomers. In cross-linked form, these blended co-polymers can yield specialty superabsorbent polymers.
