Calcium Sulphate Supplier in Malaysia
- Also known as
- Calcium Sulfate
- CaSO4
- E516
Calcium sulphate supplier for food processing, construction, manufacturing, agriculture and technical buyers in Malaysia. Also called calcium sulfate, CaSO4 and food additive E516, this white mineral salt is selected by hydrate form and grade rather than as a single interchangeable powder.
Commercial forms include anhydrous calcium sulphate, dihydrate gypsum, hemihydrate plaster of Paris, food-grade E516 and technical or casting grades. Gypsum and plaster of Paris are hydrate forms of the same salt, not separate chemicals, but they are not drop-in substitutes for each other in settable or food systems.
Food processors use suitable grades as firming agents, coagulant aids or mineral sources. Construction and manufacturing buyers specify gypsum or plaster of Paris for plaster, moulds, casting and ceramics, while agriculture may use dihydrate as a calcium and sulphur mineral. This page does not cover lime plaster, hydrated lime or finished gypsum board installation.
Send the required hydrate or form, grade, application, target specification, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation.

Calcium Sulphate 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 |
|---|---|---|---|---|
| Anhydrous calcium sulphate | white powder or fine granules | — | Dry process formulations, fillers and technical duties where no water of crystallisation is wanted, or where the anhydrous salt is named on the specification. | Confirm the required pack format with the quotation. |
| Calcium sulphate dihydrate (gypsum) | white to off-white powder or fine crystals | — | Construction and process fillers, soil amendment, ceramics and other applications that specify gypsum dihydrate rather than plaster or anhydrous material. | Confirm the required pack format with the quotation. |
| Calcium sulphate hemihydrate (plaster of Paris) | white fine powder | — | Casting, moulds, plaster work and settable systems. Alpha and beta hemihydrate differ in setting and strength behaviour, so state the performance target when known. | Confirm the required pack format with the quotation. |
| Food grade calcium sulphate (E516) | white powder suitable for food-contact processing grades | — | Food processing as a firming agent, coagulant aid, carrier or mineral source where E516 or an equivalent food-grade specification is required. | Confirm the required pack format with the quotation. |
| Technical or casting grade calcium sulphate | industrial powder matched to process mesh and purity | — | General industrial filler, ceramics, moulding compounds and process-aid use where a technical or casting specification is named rather than a food-grade limit. | Confirm the required pack format with the quotation. |

Calcium Sulphate applications
Safety and handling
Store dry and sealed, off the floor. Protect from moisture so the powder stays free-flowing and hydrate identity is preserved. Control dust during handling and follow the safety information for the quoted grade.
Common questions about calcium sulphate
Is calcium sulfate the same as calcium sulphate?
Yes. Calcium sulfate is the American spelling of calcium sulphate. Both refer to CaSO4. The hydrate form and grade still need to be stated because anhydrous material, gypsum dihydrate and plaster of Paris hemihydrate are not interchangeable in most applications.
What is the difference between anhydrous, gypsum and plaster of Paris?
Anhydrous calcium sulphate has no water of crystallisation. Gypsum is the dihydrate form. Plaster of Paris is the hemihydrate form, often used for casting and settable plaster systems. Alpha and beta hemihydrate differ in setting and strength behaviour. Name the hydrate and performance target rather than treating all forms as one stock item.
Is gypsum board installation material covered on this page?
No. This page is for chemical and industrial calcium sulphate grades used as powder or process material. Finished gypsum board systems, DIY craft kits and decorative plaster products are outside the commercial scope of this catalogue enquiry.
Can food-grade calcium sulphate (E516) be supplied?
Food-processing enquiries should state the application and the required food-grade or E516 specification. Industrial or construction grades are not automatically suitable for food use. Availability, packing and documentation for the offered grade are confirmed with the quotation.
How does calcium sulphate differ from calcium carbonate or hydrated lime?
Calcium sulphate is CaSO4 in anhydrous, dihydrate or hemihydrate form. Calcium carbonate and hydrated lime are different calcium compounds with different chemistry, pH behaviour and process roles. Lime plaster is not the same material as gypsum or plaster of Paris.
What specifications should a buyer provide for calcium sulphate?
State the intended application and any required limits for hydrate form, assay or purity basis, moisture, particle size or mesh, and setting behaviour for hemihydrate. For food use, include the E516 or food-grade limit. 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 calcium sulphate price enquiry?
Provide the hydrate or form, grade, 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.
