Pulp Internal Sizing Agent Papermaking Chemical Aid

Alkyl Ketene Dimer AKD Neutral Sizing Emulsion

AKD emulsion is a cationic reactive sizing agent engineered for direct application in neutral pH papermaking systems. It delivers superior water repellency, resistance to acid/alkaline solution penetration, and improved edge penetration resistance in paper substrates.

This sizing agent optimizes key physical properties of paper, making it a critical component in manufacturing high-grade papers such as:


  • Art base paper & photo base paper

  • Electrostatic copy paper & carbonless paper

  • Double-coated paper & archival paper

  • Stamp paper & yew base paper

  • Tissue products (napkins) and specialty coated papers.

  1. Dosing Methods

    • Direct addition to high-consistency pulp slurry.

    • Post-dilution addition to the mixing chest.

    • Surface sizing (tub-sizing) on dried paper sheets.


  2. Dosage Recommendations

    • Standard Sizing: 0.1%-0.2% of absolute dry pulp (a.d.p).

    • Heavy-Duty Sizing: 0.3%-0.4% of a.d.p.


  3. Mandatory Dual Retention System


  4. A synergistic retention system combining cationic starch and polyacrylamide (PAM) must be implemented:


    • Cationic Starch Specifications:

      • Quaternary ammonium type (degree of substitution ≥0.025)

      • Dosage: 0.6%-1.2% of a.d.p.


    • Polyacrylamide (PAM) Specifications:

      • Molecular weight: 3.0×10⁶-5.0×10⁶ Da

      • Working concentration: 0.05%-0.1%

      • Dosage: 100-300 ppm


  5. Process Control


    • Maintain pulp pH within 8.0-8.5 throughout the sizing process.


Packed in plastic drum, 200 Kg or 1000Kg each, or 23tons/flexibag.


Storage temperature should be 4- 30℃.

Shelf life:3 months. This product should be stored in a dry warehouse, protected from frost and direct sunlight.
