Alkyl Ketene Dimer (AKD) wax is a cornerstone in modern papermaking, primarily serving as a neutral sizing agent to impart water resistance. NINGBO INNO PHARMCHEM CO.,LTD. offers a range of AKD wax products, including distinct grades such as 1840, 1865, and 1895, each tailored to meet specific performance requirements. Understanding these differences is crucial for paper manufacturers to select the optimal product for their operations.

The primary variations among AKD wax grades 1840, 1865, and 1895 lie in their specific performance metrics, particularly their melting points and iodine values. These parameters influence how the AKD wax behaves during the emulsification process and its ultimate effectiveness in sizing the paper.

AKD Wax 1840 typically has a lower melting point (around 47°C) and a slightly higher iodine value (around 45 gI2/100g). This grade is often favored for its ease of emulsification and its broad applicability across various paper types. It provides robust sizing performance, contributing to good water and ink resistance, making it a versatile choice for many papermaking applications.

AKD Wax 1865 generally offers a slightly higher melting point (around 50°C) and a comparable iodine value to grade 1840. This grade might be preferred in specific formulations or processing conditions where a slightly higher melting point offers processing advantages or contributes to a particular desired finish in the paper. It maintains high active ingredient content, ensuring efficient sizing.

AKD Wax 1895 is characterized by the highest melting point among these grades (around 60°C) and a slightly lower iodine value (around 43 gI2/100g). This grade can be beneficial for applications requiring enhanced stability or specific reactivity profiles. Manufacturers often choose this grade when precise control over the sizing process and final paper properties is critical.

Regardless of the grade chosen, all our AKD wax products from NINGBO INNO PHARMCHEM CO.,LTD. are produced with high active ingredients, low acid values, and in an environmentally friendly manner. When you decide to buy AKD wax, consult with our technical team to determine which grade best suits your specific papermaking machinery, furnish, and desired paper characteristics. This informed selection ensures optimal performance and cost-effectiveness.
