Alkyl Ketene Dimer Wax
Alkyl Ketene Dimer (AKD) wax is a highly effective neutral sizing agent essential for the modern paper industry. Produced from higher fatty acids, it offers a sustainable and high-performance alternative to traditional acidic sizing agents like rosin. AKD's ability to react with cellulose fibers imparts crucial hydrophobic properties to paper and board, significantly improving its resistance to liquid penetration and enhancing its overall durability and printability. This makes it indispensable for a wide range of paper grades, from packaging and printing to specialty papers.
- The benefits of AKD wax in papermaking include its excellent performance at neutral to alkaline pH levels, making it compatible with modern papermaking processes and fillers like PCC and GCC.
- AKD wax improves paper water resistance and aging performance, ensuring longevity and quality in various applications.
- The chemical properties of AKD allow it to be used in internal and surface sizing applications, providing tailored protection and functionality.
- Learning about AKD emulsion preparation is key for achieving optimal results and efficient application in paper mills.
