AKD Wax Powder (Paper Industry)

Introduction: AKD wax powder (alkyl ketene dimer) is a core raw material for neutral sizing in papermaking. It must be emulsified before use. It reacts with fibers to form a hydrophobic layer, improving water resistance, penetration resistance and printability of paper. It is suitable for cultural paper, packaging paper and food-grade paper.Advantages: neutral/alkaline sizing, compatible with calcium carbonate, durable paper, low equipment corrosion.Disadvantages: prone to hydrolysis, slow curing, higher cost than rosin.

Industry News (2026)International manufacturers such as Kemira have raised prices of AKD wax powder repeatedly due to rising raw material and energy costs.Domestic substitution is accelerating. Low-VOC, solvent-free and food-grade green AKD has become the mainstream trend.Neutral sizing continues to replace acidic sizing. The market grows steadily, and major paper mills conduct centralized bidding procurement.
