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 →Acrylic acid-maleic anhydride/acid copolymer (CAS 26677-99-6), a low-molecular-weight polycarboxylate. Used as a scale inhibitor and dispersant in industrial water treatment and as a builder and anti-redeposition agent in detergents. Supplied as an aqueous solution or spray-dried powder.
Frequently Asked Questions
What is the copolymer of maleic and acrylic acid (MA/AA) used for?
MA/AA copolymer (CAS 26677-99-6) is a low-molecular-weight polycarboxylate used as a scale inhibitor and dispersant in industrial water treatment and as a builder and anti-redeposition agent in detergents. It controls carbonate, phosphate, and sulfate scale in cooling and process water and disperses iron oxide, clay, and particulate foulants.
How does MA/AA copolymer inhibit scale?
As a polycarboxylate it sequesters hardness ions and adsorbs onto growing crystal nuclei, distorting crystal growth (threshold inhibition) and dispersing precipitated solids. This limits carbonate, phosphate, and sulfate deposits in cooling and process water systems.
What forms is MA/AA copolymer supplied in?
It is supplied as an aqueous solution or as a spray-dried powder. Aqueous grades suit liquid water-treatment programs; the powder suits dry detergent builders. Request a CoA and SDS to confirm solids content, molecular weight, and form.
What packaging is bulk MA/AA copolymer available in?
Liquid grades ship in drums, IBC totes, and bulk; powder grades ship in bags. Submit your required form, solids, and volume with your RFQ for a current quote.
What HS code is used for MA/AA copolymer?
It is classified under HS 3906.90 — acrylic polymers in primary forms, other. Confirm the final classification with your customs broker for your destination.
