Choose the product form your production line needs. Review applications, specifications and packing, then request export pricing for your quantity and destination port.
Select the right gypsum for your process
Natural gypsum is calcium sulfate dihydrate. Calcined gypsum is the hemihydrate used in setting-plaster applications. Confirm the material form before comparing specifications or prices.
Natural Gypsum Rock & Lumps
Natural calcium sulfate dihydrate for processing, calcination and construction-material production. Specify the required purity, moisture, impurities and lump size.
Product form: Gypsum rock and lumps. Size: 0–70 mm, subject to the agreed order specification.
View natural gypsum →Ground Gypsum Powder
Ground natural gypsum for applications requiring finer raw material. Grinding changes particle size; it does not turn natural gypsum into setting plaster. Confirm whether your process requires natural or calcined powder.
Review: Chemical analysis, fineness, moisture, whiteness and bagging requirements.
View gypsum powder supply →Calcined Gypsum & Plaster of Paris
Calcium sulfate hemihydrate for plaster, gypsum-board, moulding and casting requirements. Review the setting behavior and powder performance against your production process.
Published reference values: Purity 92% min; setting time 8–15 minutes; whiteness 90% min. Confirm the current COA, test methods and written specification before ordering.
View calcined gypsum →Materials for Plaster & Gypsum Board
Identify the raw material needed by your production line: natural feedstock for calcination, calcined powder or another agreed formulation. Board production, moulding and casting can require different setting and strength properties.
Send: End use, target fineness, setting time, workability, strength requirements and sample-test criteria.
