Polyacrylic Acid (PAA) Supplier in Malaysia
- Also known as
- PAA
- Poly(acrylic Acid)
- Acrylic Acid Homopolymer
- Polyacrylic Acid Homopolymer
Polyacrylic acid supplier in Malaysia for water treatment, detergent, mineral and coating formulators who buy the free-acid polymer itself. Shortened to PAA in the trade and written as poly(acrylic acid) or acrylic acid homopolymer on a specification sheet, it carries CAS 9003-01-4. It is an anionic water-soluble polymer traded either as a clear to pale yellow aqueous solution or as a dry powder.
Grades are chosen by molecular weight range and by whether the plant would rather meter a solution or dissolve a powder. Lower ranges are the usual antiscalant and detergent builder choice, while higher ranges are specified where viscosity build and particle suspension matter. Molecular weight is grade specific rather than one published figure, so state the range the process runs on.
The free acid is a different item from its sodium salt and from the crosslinked gel thickener sold as carbomer. Fully neutralised sodium polyacrylate and carbomer grades are ordered as separate products with their own pages, and acrylic acid, the monomer, is separate again. Polyacrylamide flocculants are a different chemistry altogether.
Send the function, molecular weight range, form, solids content, quantity and delivery location with your enquiry. Pack format and documentation are covered in the quotation.

Polyacrylic Acid grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Low molecular weight polyacrylic acid solution | clear to pale yellow aqueous solution | solids content is grade specific and confirmed with the quotation | The usual antiscalant choice for cooling towers, boiler feed and process water, dosed continuously at low concentration to hold hardness salts in solution. State the water chemistry and dosing point being treated. | Confirm the required pack format with the quotation. |
| Medium molecular weight polyacrylic acid solution | clear to pale yellow aqueous solution | solids content is grade specific and confirmed with the quotation | Slurry and pigment dispersion duty, where kaolin, calcium carbonate, titanium dioxide or a ceramic body has to run at high solids without the viscosity climbing. Give the mineral, solids target and mill conditions. | Confirm the required pack format with the quotation. |
| High molecular weight polyacrylic acid solution | clear to pale yellow viscous aqueous solution | — | Selected where the polymer has to build viscosity or hold particles in suspension once it is neutralised in the formulation, as in print pastes, coating colours and thickened aqueous systems. | Confirm the required pack format with the quotation. |
| Polyacrylic acid powder | white powder or granules | — | Chosen by detergent and dry-blend manufacturers who do not want to freight water, and by plants that make up their own stock solution. Note the dissolving equipment available, since dry polymer needs controlled wetting. | Confirm the required pack format with the quotation. |

Polyacrylic Acid applications
Safety and handling
Keep containers closed in a cool, dry, well-ventilated place. Solution grades are acidic and should be kept away from strong alkalis and from oxidising agents, while dry grades pick up moisture from an open bag and should be resealed. Follow the safety information issued for the grade quoted. Supply is subject to applicable requirements.
Common questions about polyacrylic acid
Is polyacrylic acid the same as sodium polyacrylate?
No. Polyacrylic acid is the free acid and sodium polyacrylate is its neutralised sodium salt, which is a separate product with its own page and its own uses. Many formulators buy the acid and neutralise it in the batch, so say which one the recipe calls for by name.
What is the difference between polyacrylic acid and acrylic acid?
One is the polymer and the other is the monomer it is made from. Acrylic acid is a reactive liquid monomer under its own page, while polyacrylic acid is the finished water-soluble polymer dosed as an antiscalant, dispersant or thickener. Order each by name so the enquiry is not mismatched.
Can polyacrylic acid be used as a thickener?
Higher molecular weight grades do build viscosity in water once they are neutralised, which is why print pastes and some coating systems use them. If the requirement is a clear gel or an emulsion thickener for a cream, that is carbomer, the crosslinked type, and it sits on its own page.
Which polyacrylic acid grade should I request?
Start from the function. Low molecular weight material is the usual antiscalant and detergent builder choice, medium ranges suit mineral and pigment dispersion, and high ranges are picked for viscosity and suspension. Send the range your process is validated on if you already know it.
Is polyacrylic acid supplied as a liquid or a powder?
Both are traded. Aqueous solutions are the common industrial form because they are ready to meter, while powder and granules suit dry detergent blends and plants that prepare their own stock solution. Confirm which form suits your dosing equipment when you enquire.
What information is needed for a polyacrylic acid quotation?
Send the function, molecular weight range, form, solids content if a solution, quantity and delivery location. Mentioning the application, such as cooling water treatment or kaolin dispersion, lets the enquiry be matched to a suitable grade.
