Alkyl ketene dimer (AKD)
is most common neutral/ alkaline sizing agent. It is an Internal sizing agents.
Structurally, it is unsaturated lactones and it is synthesized from fatty
acids. Physically it is waxy like milky emulsion chemicals. It
has less corrosive to the papermaking machine
than acid sizing. For cultural paper and packing paper.
Our chemical has developed the following products.
– Hard sizing can be applied, and the stocking sizing degree is proportional AKD usage.
Good anti-moisture effect for the paper, can effectively prevent the reduction of RCT.
