A grade-specific Safety Data Sheet (SDS) — with the complete hazard classification, handling precautions, and transport information — is supplied with every shipment and available on request. Confirm all safety and regulatory details against the SDS for your specific grade.
Request SDS →Polyacrylic acid (CAS 9003-01-4) is a water-soluble carboxylic acid polymer supplied as acid or partially neutralized solutions and powders. It is used as a dispersant, scale inhibitor, and thickener, and as a superabsorbent component in its crosslinked, neutralized form.
Frequently Asked Questions
What is polyacrylic acid used for?
Polyacrylic acid (PAA, CAS 9003-01-4) is a water-soluble carboxylic-acid polymer used as a dispersant for particulates and pigments, a threshold scale inhibitor in water treatment, a thickener for rheology control, a detergent builder that sequesters hardness ions, and — in its crosslinked, neutralized sodium form — as a superabsorbent. RawSource supplies acid and partially neutralized solutions and powders.
What is the trade name for polyacrylic acid?
Polyacrylic acid and its crosslinked derivatives are sold under various trade names (e.g., Carbomer for crosslinked grades; sodium polyacrylate for the neutralized superabsorbent form). CAS is 9003-01-4, HS code 3906.90. Request a CoA for grade identity.
Is polyacrylic acid water soluble?
Yes — linear polyacrylic acid is a water-soluble polymer supplied as acid or partially neutralized solutions and powders. The crosslinked, neutralized form is water-swellable (superabsorbent) rather than soluble. Request technical data for the specific grade.
What grades and forms of polyacrylic acid does RawSource supply?
PAA is available as free-acid and partially neutralized solutions and as powders, across a range of molecular weights. Specify your application (dispersant, scale inhibitor, thickener, builder) so the right grade can be matched, and request the SDS and CoA.
What is the price of bulk polyacrylic acid?
Bulk PAA pricing depends on molecular weight, neutralization, form, and volume. RawSource quotes to spec — request a current bulk quote with your target grade and quantity.
