What the product listing confirms

• Chemical name: Polyacrylamide, also listed as Polyacrylic amide and PAM, (C3H5NO)n
• CAS: 9003-05-8
• EINECS: 231-545-4
• Appearance (as listed): White powder
• Listed classes: Acrylates and Methacrylates; Drilling and Completion Fluids; Water Treatment Chemicals
• Packing: 25 kg/bag
• General properties: Water-soluble, insoluble in most organic solvents, good flocculation, and able to reduce friction resistance between liquids
• Manufacturing route: Made by polymerizing acrylamide (C3H5NO). The acrylamide is usually dissolved in water and polymerized with free-radical initiators.

Criterion 1: Match the ionic type to your suspension

According to the product description, Polyacrylamide comes in four ionic types: non-ionic, anionic, cationic and amphoteric. The listing gives these application guidelines:

Before you choose, check three things about your stream: whether the solids are mainly organic or inorganic, their surface charge, and whether the solution is acidic, neutral or basic. If your conditions do not fit any of the descriptions above, these guidelines alone are not enough to make a choice. Ask for technical review and trial samples first.

Criterion 2: Choose a physical form that suits your handling

Polyacrylamide can come as granules, liquid oil emulsion, tablets or blocks. The product description lists these trade-offs:

• Dry forms are easier to store, transport and meter into head ditches, and they keep longer than liquid forms.
• Liquid forms need less agitation to dissolve.

The technical information in this listing describes the product as a white powder packed in 25 kg bags. If you need a liquid emulsion, tablet or block form, ask whether that form is available. This article does not confirm availability.

Criterion 3: Check that the application category fits

The listing places this Polyacrylamide in water treatment chemicals, drilling and completion fluids, and acrylates and methacrylates. If your use falls outside these categories, confirm that the grade is suitable before you buy.

Criterion 4: Confirm the specifications your process needs

The confirmed material gives no data on molecular weight, degree of ionicity (charge density), solid content, dissolution time, residual monomer, dosage or test methods. If your process depends on any of these values, ask for a specification sheet or certificate of analysis for the exact grade you are offered, and run your own jar or field tests.

What this guide does not cover

This article makes no claims about price, lead time, minimum order quantity, certifications or export documents for any market. Confirm these directly with the supplier. It also gives no dosing or operating instructions. Follow the safety data sheet and handling guidance for the specific product you receive.

Buyer checklist

1. Describe your suspension: organic or inorganic, surface charge, pH range, particle size.
2. Choose a likely ionic type using the table above.
3. Choose a physical form that suits your storage, transport and dissolving equipment.
4. Confirm the CAS number (9003-05-8) and the packing (25 kg/bag) on the quotation.
5. Request a grade specification and safety documents, and test samples before you place a volume order.
