Gypsum

Gypsum (CAS 13397-24-5), also sold as mineral white, is a naturally occurring calcium sulfate dihydrate.

Where is Gypsum used?

• Construction: primary raw material for drywall, plaster, and cement retarders
• Agriculture: soil conditioner improving structure in clay-heavy fields and supplying calcium and sulfur without altering pH
• Food manufacturing: coagulant in tofu production and calcium-fortifying agent in beverages and baked goods
• Paper manufacturing: filler and coating pigment that improves sheet brightness and printability
• It functions as a setting agent and rheology modifier depending on the sector.

Good to know: Purity levels and particle size distribution are the primary specification variables buyers should confirm with suppliers. Food-grade and FCC-compliant grades are available for direct food contact; technical and agricultural grades cover uses where high purity is not the primary concern.
