alkyl ketene dimer
Product name: Alkyl Ketene Dimer
Synonyms: Alkyl Ketene Dimer Wax, AKD, AKD WAX
CAS No: 144245-85-2
AKD WAX is pale yellow waxy flake solid, 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.
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: 48.0-50.0
Physical State: Flakes
Applications: AKD and ASA 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.
Advantages: Compare to Acidic sizing agent (Gum Rosin) , The Neutral / Alkaline Sizing Agent (AKD) 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.
Production Capacity: 3000mt annually, the maximum is 400mt monthly.
Packing: 25kg woven bag
