Alkyl Ketene Dimer Supplier in Malaysia for Paper Sizing
- Also known as
- AKD
Alkyl ketene dimer supplier for paper mills and paper-chemical formulators in Malaysia. Commonly abbreviated AKD, this reactive sizing material is used to reduce liquid penetration in paper and paperboard made under neutral or alkaline conditions.
AKD wax is the neat active material supplied as flakes, granules or pastilles for emulsion manufacture. AKD emulsion is a finished aqueous dispersion whose active or solids content, stabiliser system, particle characteristics, charge, viscosity, pH and storage stability form part of the product specification.
Paper mills meter AKD emulsion into the wet end for internal sizing of printing and writing paper, packaging grades, liner and paperboard. Performance depends on the furnish, filler, water chemistry, retention programme, dosing point and target sizing level, so the emulsion name alone is not a complete selection basis.
Send the required wax or emulsion form, paper grade, process conditions, specification, quantity and delivery location with your enquiry. Packing, available technical documentation, quotation validity and delivery timing are confirmed for the offered material.

Alkyl Ketene Dimer grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Alkyl ketene dimer wax | white to pale yellow waxy flakes, granules or pastilles | — | Active AKD material for paper-chemical formulators producing an aqueous sizing emulsion to their own active-content, charge and stability design. | The solid form and pack format are confirmed with the quotation. |
| Alkyl ketene dimer emulsion | milky white aqueous dispersion at a specified active or solids content | — | Internal sizing of paper and paperboard on machines equipped to store, meter and add an AKD emulsion under the mill's wet-end programme. | The emulsion specification and pack format are confirmed with the quotation. |

Alkyl Ketene Dimer applications
Safety and handling
Keep AKD wax closed, cool and dry, protected from moisture, contamination and excessive heat. Keep emulsion containers closed and protect them from temperature extremes, contamination and prolonged storage outside the supplier's stated conditions. Follow the handling information for the quoted form.
Common questions about Alkyl ketene dimer
What does AKD mean in papermaking?
AKD means alkyl ketene dimer, a reactive sizing material used to reduce liquid penetration into paper and paperboard. It is commonly applied as an aqueous emulsion in the wet end of the paper machine.
What is the difference between AKD wax and AKD emulsion?
AKD wax is the neat waxy active material used to manufacture a sizing dispersion. AKD emulsion is a formulated aqueous product containing dispersed AKD together with the stabilising system needed for storage, pumping and wet-end addition.
Is every AKD emulsion the same formulation?
No. Emulsions can differ in AKD active or solids content, stabiliser system, particle characteristics, charge, viscosity, pH and storage stability. Buyers should compare the full formulation specification and mill trials, not the AKD name alone.
Is wax size a sufficient product description for an enquiry?
No. Wax size can refer broadly to a paper-sizing product and does not show whether the buyer needs neat AKD wax or a finished AKD emulsion. State the material, form and paper application explicitly.
How should an AKD emulsion be selected for a paper machine?
Selection considers furnish, recycled-fibre content, filler system, pH, water chemistry, retention programme, dosing point and target sizing level. Include these conditions so a relevant emulsion specification can be quoted and evaluated at the mill.
Which specifications matter when buying AKD wax?
State the required active basis, appearance, melting behaviour and impurity limits, together with the intended emulsion-making process. Physical form and handling needs should also be included.
What details are needed for an Alkyl ketene dimer quotation?
Provide wax or emulsion form, paper grade, furnish and process conditions, target sizing result, specification, quantity and delivery location. Add packing and technical-document requirements for confirmation with the quotation.
