Kaolin (China Clay) Supplier in Malaysia
- Also known as
- China Clay
- White Clay
- Kaolin Clay
Kaolin supplier for paint, paper, ceramics, rubber and plastics manufacturers in Malaysia. Also called china clay, white clay or kaolin clay, this hydrated aluminium silicate mineral is selected for whiteness, fine particle size, plasticity when wet and clean behaviour in fired or filled systems.
Commercial grades include hydrous china clay, calcined kaolin and fine paper coating material. Hydrous grades support ceramic bodies, paper filler and general extender work, while calcined grades are chosen where higher brightness and opacity matter in coatings, paper coating and selected polymer compounds.
Coating formulators use kaolin as an extender and functional pigment; ceramic producers rely on it for plasticity and firing colour; paper mills use it as filler and coating clay; rubber and plastics compounders use it to improve processability, stiffness and cost without strong colour contribution.

Kaolin 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 |
|---|---|---|---|---|
| Hydrous kaolin (china clay) | fine white powder | — | Ceramic bodies and glazes, paper filler, rubber and plastic compounding, and general extender work where plasticity, whiteness and fine particle size are the selection drivers. | Confirm the required pack format with the quotation. |
| Calcined kaolin | heat-treated white powder | — | Paint and coating systems, paper coating and selected polymer compounds where higher brightness, opacity and lower moisture than hydrous china clay are required. | Confirm the required pack format with the quotation. |
| Paper coating kaolin | fine, controlled particle-size powder | — | Paper coating and high-brightness filler duties where print surface, gloss and ink holdout depend on particle size distribution and brightness. | Confirm the required pack format with the quotation. |

Kaolin applications
Safety and handling
Store dry and sealed, off the floor. Protect from moisture so the powder stays free-flowing. Control dust during handling and follow the safety information for the quoted grade.
Common questions about kaolin
Is china clay the same as kaolin?
Yes. China clay is the established trade name for kaolin, the white kaolinite clay used in ceramics, paper, paint, rubber and plastics. The enquiry should still name the grade, because hydrous and calcined material behave differently in formulation and processing.
What is the difference between hydrous and calcined kaolin?
Hydrous kaolin is the natural, washed china clay, valued for plasticity and fine particle size in ceramics, paper filler and general extender work. Calcined kaolin is heat-treated to remove structural water, which raises brightness and opacity and is often preferred in coatings, paper coating and selected polymer systems.
Which kaolin grade should I request for paint, paper or ceramics?
Ceramic bodies and glazes usually start from hydrous china clay for plasticity and clean firing. Paper coating and high-opacity paint systems often specify a fine or calcined grade with stated brightness and particle size. Describe the process and performance target so the grade can be matched more closely.
What specifications should a buyer provide for kaolin?
State the intended application and any required limits for brightness, particle size or mesh, moisture, residue on sieve, oil absorption and colour. For a formulation already in production, include the current specification or a representative sample requirement.
Can documentation and packing be requested with the quotation?
Yes. List the required product documents and preferred pack format in the enquiry. Available documentation, packing and commercial details are confirmed for the quoted grade.
What details are needed for a kaolin price enquiry?
Provide the grade or form, application, target specification, quantity and delivery location. Mention any preferred pack format, documentation needs and required timing so the quotation can address the complete requirement.
