1. Product Overview & Specifications

Alkyl Ketene Dimer (AKD), CAS 144245-85-2, is a pale yellow solid (block or flake) synthesized from higher fatty acids (C≥12) through acylation and dehydrochlorination. Key parameters include:

2. Industrial Applications

AKD serves as a critical raw material for:

• Neutral Sizing Agent Production: Forms emulsifiable wax for papermaking under pH 8.2 conditions.
• Paper Hydrophobicity Enhancement: Reacts with cellulose hydroxyl groups to create water-resistant bonds.
• Packaging Material Optimization: Improves moisture resistance in corrugated boards and food-grade packaging.

3. Usage Scenarios

3.1 Paper Manufacturing Process

Typical dosage: 0.05–0.2% of pulp weight. AKD is emulsified with cationic starch (1:3 ratio) before addition to pulp slurry. Curing at 50–60°C ensures complete reaction.

3.2 Specialty Paper Production

In thermal paper manufacturing, AKD-modified surfaces show 30% improved ink adhesion and 25% reduced curling under humidity.

4. Client Case Studies

Case 1: Packaging Board Manufacturer (Hubei, China)

Challenge: Reduce sizing costs while maintaining Cobb30 ≤ 20g/m².
Solution: AKD-based emulsion at 0.15% dosage with cationic starch.
Result: 18% cost reduction, Cobb30 = 18.5g/m², ROI achieved in 6 months.

Case 2: Cultural Paper Mill (Zhejiang, China)

Challenge: Eliminate alkaline darkening in premium writing paper.
Solution: pH-neutral AKD sizing system (pH 7.8–8.2).
Result: ISO brightness maintained at 92%, zero yellowing after 12-month storage.
