NINGBO INNO PHARMCHEM CO.,LTD. is proud to present its premium Alkyl Ketene Dimer (AKD) Wax, a cutting-edge sizing agent revolutionizing the paper and paperboard industry. Our AKD Wax stands as a testament to sustainable innovation, offering superior performance while adhering to stringent environmental standards. Designed for diverse industrial applications, it ensures enhanced paper quality and process efficiency.

Alkyl Ketene Dimer (AKD) is a family of organic compounds based on the oxetan-2-one ring system, functioning primarily as a fiber-reactive neutral sizing agent. Historically, AKD emerged as a superior alternative to traditional acidic rosin sizing, allowing for papermaking in neutral or alkaline environments. This shift has significantly reduced corrosion on machinery and enabled the use of alkaline fillers like calcium carbonate, promoting more eco-friendly production processes. AKD's unique structure, featuring hydrophobic alkyl groups, reacts effectively with the hydroxyl groups on cellulose fibers through esterification, thereby anchoring a water-repellent layer onto the paper surface.

Our AKD Wax offers numerous benefits that elevate paper product quality and streamline manufacturing. Its eco-friendly nature is paramount, produced through a solvent-free method that ensures the absence of toxic substances, making it particularly suitable for paper grades requiring high hygiene standards, such as liquid food packaging paper.
Compared to traditional sizing agents, AKD Wax allows papermaking at a neutral to weakly alkaline pH (7.5-8.5), which is considerably more environmentally sound. This neutral sizing condition leads to less corrosion on paper machines, extending equipment lifespan and reducing maintenance costs.
Furthermore, the application of AKD Wax significantly improves the strength and whiteness of paper, maintaining these enhanced properties over extended periods. It imparts excellent water resistance and contributes to better printability by controlling the penetration of liquids and inks. This versatility makes it an ideal choice for a wide range of paper products.

The applications of our AKD Wax extend across numerous sectors within the paper industry. It is widely utilized as both an internal and surface sizing agent for various paper types, including cultural paper, newsprint, paperboard, fruit bag paper, and general wrapping paper. Its ability to meet non-toxic standards makes it indispensable for food packaging paper, where product safety and hygiene are paramount. Beyond papermaking, Alkyl Ketene Dimer has also found specialized uses as a cross-linking agent in optical systems, where its capacity to absorb ultraviolet light is highly valued in the production of optical lenses.

NINGBO INNO PHARMCHEM CO.,LTD. offers a range of AKD Wax grades, including AKD Wax 1840, AKD Wax 1865, and AKD Wax 1895, each meticulously manufactured to precise specifications. These grades are characterized by their light yellow flake or granular solid appearance and boast high active ingredient content (typically ≥88% to ≥90%). They feature specific melting points (ranging from ≥47°C for 1840 to ≥60°C for 1895), iodine values (e.g., 45gI2/100g for 1840), and low acid values (≤5mgKOH/g), ensuring consistent performance. Our products typically maintain a shelf life of 180 days when stored correctly at temperatures below 25°C.
