Anionic Polyacrylamide APAM 0.05% Max Residual Monomer for Drilling Fluid Rheology Modification CAS 9003-05-8 ISO 9001 Manufacturer 25kg PE Bag

Product overview

Rheology modification means controlling how a drilling fluid responds across different flow and rest conditions. A useful polymer must contribute to the desired carrying and handling behavior without producing unacceptable pressure demand, gels or solids-control problems. A single viscosity number captures only part of that requirement.

Bluwat APAM candidates can be compared for concentration response and compatibility with the mud. The selected molecular weight and charge should be documented, because the general family range includes grades with different behavior. The residual-monomer limit is a quality parameter and does not rank their rheological performance.

Product benefits

Technical specifications

Grade selection for this application

Define the target plastic viscosity, yield response, low-shear readings and gel development using the project's test procedure. Provide water chemistry, solids loading and the full additive list, including any materials that disperse or flocculate clay.

Compare results before and after aging and representative mechanical exposure. Avoid transferring an ambient clean-water result directly to the drilling fluid. If viscosity rises unexpectedly, examine hydration, solids accumulation and additive interaction before responding with further polymer addition.

Application evaluation and use

Solution preparation and dosing

Use clean, compatible make-up water and add the powder gradually into an established mixing flow. Avoid dumping powder in one location, which can create lumps with dry cores. The TDS gives 0.1–0.5% as general solution-preparation guidance. If specified on an as-supplied powder mass basis, this corresponds to 1–5 kg of powder per 1,000 kg of final solution; agree the concentration basis for the project.

Allow approximately one hour of agitation as a starting reference, then confirm complete hydration. Water quality, temperature, grade and equipment affect the required time. The TDS’s 200–400 rpm reference is equipment dependent and should not be scaled to a different tank solely by rpm. Avoid severe shear after hydration. Determine the final treatment dosage through the application tests described above.

Packaging storage and handling

The featured packaging is a 25 kg PE bag with an inner plastic liner. The TDS also lists 25 kg kraft paper or PE bags and 750 kg net big bags. Store powder dry, protected from direct sunlight and at 0–35°C. Keep opened packaging tightly closed. Consult the current SDS for handling, spill control and personal protection.
