Alkyl Ketene Dimer AKD Wax

Alkyl Ketene Dimer (AKD) wax from Yanzhou Tiancheng Chemical Co., Ltd. is a pale yellow flake or granular solid produced in Shandong Province, China. The material carries CAS registration number 144245-85-2 and is synthesised from C16 fatty acid via acylation and dehydrochlorination. Its melting point sits at approximately 47 to 51 degrees Celsius, and it dissolves in ethyl alcohol, benzene, chloroform and comparable organic solvents. The reactive ketone group in the AKD molecule enables esterification with cellulose hydroxyl groups, forming covalent bonds that anchor the hydrophobic alkyl chains to paper fibres.

The product is supplied as a wax intermediate rather than a finished emulsion. Buyers convert it into AKD emulsion on site through melt-emulsification with cationic emulsifiers, followed by high-speed shearing and high-pressure homogenisation before cooling. The resulting cationic particles carry positive charge through adjuncts such as cationic starch and polyacrylamide retention aids, which promote fibre attachment during the wet end of the paper machine. Octadecyl and cetyl variants of AKD are standard for neutral sizing in papermaking; the specific alkyl chain distribution affects melting behaviour and reactivity with cellulose.

Papermills and paperboard producers purchase AKD wax to impart fluid resistance to packaging, printing and writing grades. Neutral sizing with AKD replaces traditional acidic rosin sizing, improving paper longevity and allowing calcium carbonate filler loading. Buyers should confirm the iodine value, acid value and saponification number with Yanzhou Tiancheng Chemical Co., Ltd. to match their emulsion formulation. Storage and handling conditions, including melt temperature and nitrogen blanketing, should be discussed directly with the supplier.

Yanzhou Tiancheng Chemical Co., Ltd. is located at No. 66 West of Beizhan Road, Yanzhou, Shandong Province, 272117, China. The company holds a harbor trust tier on the platform, with a response rate of 0.00 percent and no recorded average response time. Buyers should note the absence of response data and plan communications accordingly, allowing extra time for quotation and sample requests.
