We have 22 years producing Alkyl Ketene Dimer history, and the output is 30000 Tons per year.

Comparing to rosin size, AKD sizing agent is a chemical treatment that reduces machine breakdown and water recycling difficulties of the standard acidic paper manufacture process by minimizing water absorption and enhancing the surface conditions of paper during a neutral paper manufacturing process.AKD plays a significant role in minimizing the detrimental environmental impact of water contamination by facilitating the recycling of water in the paper production process. In particular, the reactive neutral sizing AKD emulsion produced by us has increased the amont of AKD particles per unit volume through effective dispersion,resulting in improved sizing effects in the rang of PH 6.5- 9.0.
