Product Introduction

Retention Chemistry Is a System, Not a Single Additive

Anionic PAM may work in selected dual-polymer or cationic-demand-controlled programs, but it is not a universal substitute for a cationic retention aid. The preferred chemistry depends on furnish charge, fillers, dissolved and colloidal substances, wet-end additives, chemical sequence, addition point, and shear.

A successful program must improve first-pass retention and drainage without harming formation, strength, sizing, deposits, machine cleanliness, breaks, or finished-paper quality.

Blufloc APAM Emulsion

Blufloc APAM emulsion can be evaluated as an anionic bridging component in selected papermaking retention and drainage programs.

EWA 7520 and EA 6520 are screened together with cationic starch, coagulant, microparticle, furnish charge, chemical sequence, addition point, and the machine's actual shear history.

Application Challenges

Balance Retention, Drainage, Formation, and Runnability

A wet-end program that improves one number can still reduce paper quality or machine stability. Polymer selection therefore requires a system-level comparison under representative furnish and shear.

High Filler and Fines Load

Mineral fillers, short fibers, and fines may escape the sheet unless the charge and bridging system is correctly balanced.

Strong Machine Shear

Fan pumps, pressure screens, cleaners, piping, and the headbox can break useful microfloc before it reaches the wire.

Charge Interactions

Cationic starch, coagulants, fixatives, sizing chemicals, pitch-control agents, and microparticles all influence APAM response.

Performance Trade-Offs

Higher retention or faster drainage can come with poorer formation, deposits, weak sizing, sheet defects, or more breaks.

Wet-End Mechanism

How the PAM Emulsion Works

Very-high-molecular-weight anionic polymer chains can bridge furnish components that have been pre-conditioned with cationic starch or a suitable coagulant. Addition point and shear history determine whether useful microfloc reaches the wire or breaks before drainage.

Stage 1

Condition Furnish Charge

Establish the intended cationic starch, coagulant, fixative, or other cationic component before adding APAM.

Stage 2

Create Controlled Bridging

Activated APAM links suitable furnish components into microfloc without intentionally producing oversized floc.

Stage 3

Manage Shear Before the Wire

Choose the addition point so controlled shear produces a stable size distribution for retention, drainage, and formation.

Important: The grades below are starting candidates, not a fixed prescription. Final selection and dosage require representative laboratory and machine trials. APAM is recommended only where furnish and charge studies support an anionic retention component.

Recommended Grades

Recommended Blufloc Grades

Compare candidates at equal active polymer mass using real furnish, the actual chemical sequence, representative consistency, white-water chemistry, temperature, and machine-relevant shear.

Grade	Base	Molecular Weight	Charge	Suggested Screening Role
EWA 7520	Water-based	Very High	Medium anionic	Primary water-based candidate for selected wet-end trials
EA 6520	Oil-based	Very High	High anionic	Comparator when higher anionic character is required

The product pages classify the cationic EC and EWC series as high molecular weight and the anionic EA and EWA grades as very high molecular weight. Confirm exact commercial specification limits, active content, viscosity, shelf life, and preparation instructions on the current grade-specific TDS and order specification.

Application Process

Screen the Entire Wet-End Program Before a Machine Trial

Review Furnish and Charge

Complete a wet-end charge, furnish, filler, white-water, and chemical-sequence review before selecting APAM.

Run Dynamic Wet-End Tests

Use real furnish for dynamic drainage, retention, formation, and floc-size testing with the actual chemical order.

Select the Addition Point

Place APAM after the relevant cationic component while considering fan-pump, screen, piping, headbox, and approach-flow shear.

Evaluate the Whole Sheet

Measure first-pass retention, drainage, formation, strength, sizing, deposits, sheet defects, cleanliness, and breaks together.

Run a Controlled Machine Trial

Confirm the selected grade, dose, dilution, and addition point with quality, production, runnability, and wet-end teams present.

Product Selection Guidance

Use APAM Only Where the Charge Study Supports It

EWA 7520 is the preferred first candidate for a compatible water-based automatic wet-end system. EA 6520 provides a higher-anionic comparator when furnish, cationic-demand, and interaction studies indicate that stronger anionic character should be evaluated.

Do not treat either grade as a universal replacement for cationic retention aid. Re-screen when furnish, filler, recycled-fiber content, broke, conductivity, cationic starch, sizing, coagulant, microparticle, or machine shear changes materially.

Compare Total Operating Cost

Neat-emulsion price per kilogram can be misleading. Compare active polymer mass together with preparation efficiency, dose, machine speed, steam and vacuum demand, sheet quality, broke, deposits, downtime, and total wet-end chemical cost.

Troubleshooting

Protect Formation and Wet-End Compatibility

Do Not Optimize Retention in Isolation

If retention rises but formation worsens, reduce dose or move the addition point to introduce more controlled shear before the forming section. Check drainage and floc-size distribution before accepting the higher retention result.

If deposits increase, review charge balance and compatibility with cationic starch, sizing, fixatives, pitch-control products, fillers, broke, and microparticle programs. A deposit problem should not be treated only as a polymer-dose problem.

Safe Handling

Storage and Handling

Keep the package sealed in a cool, dry, ventilated area. Protect it from direct sunlight, freezing, and excessive heat.

Follow the grade-specific TDS and SDS for shelf life, handling limits, and transport classification. Polymer spills can make floors extremely slippery and should be contained and cleaned promptly.

Frequently Asked Questions

Papermaking Retention and Drainage FAQ

Is anionic PAM a universal paper retention aid?

No. It is suitable for selected furnish and charge conditions, often as part of a dual-polymer or coordinated wet-end program. Furnish-specific testing is essential.

What should be tested besides retention?

Drainage, formation, strength, sizing, deposits, sheet defects, broke, cleanliness, breaks, and overall machine runnability should all be checked.

Why does the APAM addition point matter?

Fan-pump, screen, piping, and headbox shear determine microfloc size and survival before the forming section. The addition point therefore affects retention, drainage, and formation.

Can wastewater-grade test results predict wet-end performance?

No. Paper-machine furnish, chemical interactions, shear history, drainage, and product-quality requirements require a dedicated dynamic wet-end evaluation and controlled machine trial.

Controlled Wet-End Screening

Match APAM to Furnish Charge, Chemical Sequence, and Machine Shear

Screen EWA 7520 and EA 6520 only where furnish and charge studies support an anionic retention component. Confirm the preferred grade, active dose, dilution, and addition point using first-pass retention, drainage, formation, strength, sizing, deposits, cleanliness, breaks, runnability, and total operating cost.
