Alkyl Ketene Dimer AKD Wax For Paper Making

Product Name: AKD Wax 1840 CAS No: 84989-41-3 Synonyms: Alkyl Ketene Dimer, 2-Oxetanone, 3-C12-16-alkyl-4-C13-17-alkylidene derivative Molecular Formula: C28H52O2 to C36H68O2 Molecuar Weight: 420 to 532      Molecular Structure:           R1= C12-16 ; R2=C12-16 Carbon Chain C16/C18 Percentage in AKD: Carbon 16 (C16): 60% Carbon 18 (C18): 40%   Description: AKD Wax is pale yellow waxy solid in granule, it is widely used in the paper industry as sizing agent. After sizing with AKD emulsion, it can make paper less water absorbing and controls its printing properties.   Specification: Appearance: Pale Yellow Waxy Solid Assay: 90% min. Iodine Value, g I2/100g: 45 min. Acid Value, mg KOH/g: 5.0 max. Melting Point, C: 48-50 min.   Application: Used as the raw material to produce 15%, 20% AKD emulsion, which is the advanced internal sizing agent for paper-making industry.   Advantage: AKD have become more frequently used in the papermaking industry during the last decade as neutral sizing agent which has replaced the acidic sizing agent (Gum Rosin) greatly. 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 amount of AKD particles per unit volume through effective dispersion, resulting in improved sizing effects in the range of pH 6.5~9.0.   Packing: 25kg woven bag, 16mt /FCL Storage and Transportation: Keep away from direct sunlight and dampness, Store in a cool, dry and ventilated place, the storage temperature of not more than 35 deg C is recommended.
