Wollastonite Supplier in Malaysia
- Also known as
- Calcium Metasilicate
- CaSiO3
Wollastonite supplier in Malaysia for plastics, coatings, rubber, friction and ceramic manufacturers. Wollastonite is a naturally occurring calcium silicate mineral, CaSiO3, valued as a functional filler and reinforcing mineral in formulations that control particle size and morphology.
Acicular grades retain a needle-like shape for reinforcement, while fine ground powders serve filler and extender duties where dispersion and surface finish are important. Ceramic grades are selected by mineral chemistry, particle size and firing behaviour for bodies, glazes and related products.
Applications include engineering plastics, rubber compounds, paints, sealants, friction materials and ceramic manufacture. Buyers may also specify surface treatment, aspect ratio, brightness, moisture and mineral impurity limits to suit an established compound or process.
Send the required grade, morphology, particle specification, quantity and delivery location for a quotation. Availability, packing, documentation and delivery timing are confirmed for the quoted wollastonite requirement.

Wollastonite 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 |
|---|---|---|---|---|
| Acicular wollastonite | needle-like mineral powder with controlled aspect ratio | — | Reinforcement in engineering plastics, friction materials and coatings where particle shape contributes to dimensional stability and mechanical performance. | Sealed powder packing is confirmed for the required grade and quantity. |
| Fine ground wollastonite | fine white to off-white mineral powder | — | Functional filler and extender in paints, sealants, rubber, plastics and construction compounds where particle size, brightness and dispersion are specified. | Pack format is confirmed against the required particle-size grade. |
| Ceramic grade wollastonite | ground calcium silicate mineral powder | — | Ceramic bodies, glazes and related mineral formulations where calcium and silica contribution, particle size and firing behaviour are defined by the manufacturer. | Packing and supporting documents are confirmed with the quotation. |

Safety and handling
Keep wollastonite dry, sealed and protected from contamination. Control airborne dust during transfer and follow the safety information supplied for the quoted particle-size and surface-treatment grade.
Common questions about Wollastonite
Should I request acicular or fine ground wollastonite?
Acicular grades are chosen when needle-like morphology and reinforcement are important, such as in engineering plastics or friction materials. Fine ground grades suit filling, extending and dispersion duties in coatings, sealants, rubber and mineral compounds.
What specifications matter when buying wollastonite?
State particle-size distribution, aspect ratio for acicular grades, brightness, moisture, surface treatment and any controlled mineral impurities. Include the polymer, coating, friction or ceramic application so the grade can be matched.
Is wollastonite the same as other calcium silicate powders?
No. Wollastonite is a specific calcium silicate mineral with characteristic mineralogy and often an acicular particle shape. Synthetic or hydrated calcium silicate products can have different structures and performance.
When is surface-treated wollastonite useful?
A treated grade may improve compatibility and dispersion in selected polymers, coatings or sealants. State the resin system, treatment preference and target properties rather than assuming one treatment suits every formulation.
How are wollastonite packing and documents confirmed?
State the particle grade, preferred pack format and any product documents required. Available packing, documentation and commercial details are confirmed for the quoted material.
What information is needed for a wollastonite price enquiry in Malaysia?
Send the morphology, particle size, aspect ratio, treatment, application, quantity and delivery location. Mention required documents and timing so the quotation can address the complete requirement.
