What purity does Berenex calcinated gypsum reach?
≥95% CaSO₄·½H₂O, processed from high-purity Eastern Desert natural gypsum with a feed purity of ≥94.89%. Whiteness is ≥95 L* and moisture is ≤0.5%.
What is the minimum order quantity for calcinated gypsum?
500 metric tonnes (MT). Available in 50 kg polypropylene bags, big bags (1,000–1,250 kg FIBC), or bulk vessel loading. Shipped FOB Port Said or CIF to destination.
What are the main industrial uses of calcinated gypsum?
Plasterboard and drywall manufacturing, construction wall plaster and renders, dental and orthopaedic plasters, pottery and art casting moulds, ceramic mould-making for slip casting, and as a retarder in Portland cement clinker production.
