Brief Introduction of AKD Wax Powder

AKD wax powder is the raw material for neutral reactive sizing agent in papermaking. It is a white/light yellow waxy solid and must be emulsified into AKD emulsion before use. It reacts chemically with cellulose during drying on the paper machine to endow paper with water resistance.✅ Advantages: Neutral papermaking, more calcium carbonate filler can be added to improve brightness; suitable for copy paper, packaging paperboard and food-grade paper.⚠️ Disadvantages: Curing time required; improper use may cause deposits on paper machine and slippery paper surface; prone to hydrolysis and deactivation.
