AKD Wax Powder (Alkyl Ketene Dimer) is the core raw material for mainstream neutral sizing agents in papermaking.
Properties: Off-white waxy solid, insoluble in water, high reactivity, capable of bonding with paper fibers to provide water resistance.
Main Grades: 1865 general grade, 1840 low-temperature grade, 1895 high-temperature special grade.
Main Applications: Water-resistant sizing for offset paper, white cardboard and food packaging paper.
Core Advantages: Suitable for neutral papermaking, no equipment corrosion, improved paper durability; substitute for traditional acidic rosin size.
Features: Delayed curing effect of sizing; the water resistance of finished paper improves over time.
