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 →Sodium polymethacrylate (CAS 54193-36-1) is an anionic polyelectrolyte, the sodium salt of poly(methacrylic acid), supplied as an aqueous solution. As a polycarboxylate it functions as a dispersant, scale or threshold inhibitor, and rheology modifier for mineral and pigment slurries and water-treatment systems.
Frequently Asked Questions
What is sodium polymethacrylate used for?
Sodium polymethacrylate (Na-PMA, CAS 54193-36-1) is an anionic polycarboxylate supplied as an aqueous solution. It functions as a dispersant for mineral, pigment, and ceramic slurries, a scale or threshold inhibitor in water-treatment systems, and a rheology modifier for aqueous suspensions. RawSource supplies it in bulk for these industrial applications.
Is sodium polymethacrylate the same as sodium polyacrylate?
No. Both are anionic polycarboxylate dispersants, but sodium polymethacrylate is the sodium salt of poly(methacrylic acid) while sodium polyacrylate is the salt of poly(acrylic acid). The extra methyl group affects performance, so the two are not drop-in interchangeable. Confirm CAS 54193-36-1 on the CoA.
What happens when you mix sodium polymethacrylate with water?
It is already supplied as an aqueous solution, and the polymer disperses fully in water to form an anionic polyelectrolyte that disperses minerals and inhibits scale. Unlike a superabsorbent polymer it does not gel into a solid; it stays a pourable solution. This solution behavior is what enables its dispersant and antiscalant function.
What is the solids content of sodium polymethacrylate solution?
Active-polymer (solids) content varies by grade and is stated on the CoA for each lot, so it should not be assumed. Tell us your required actives level and viscosity when requesting a quote. RawSource will confirm the matching grade specification.
What bulk packaging is sodium polymethacrylate solution available in?
As an aqueous solution it ships in drums, totes, or IBCs matched to your order volume. Request a quote with your target quantity and we will return delivered pricing along with a CoA and SDS.
