Arbyan Investment & Development supplies building gypsum for plaster, finishing materials and construction-product manufacturing. Send us your required grade, specifications, quantity and destination port to request a quotation. Product Overview Building gypsum is a calcined gypsum material containing calcium sulphate hemihydrate. When mixed with water, it hydrates and sets to form hardened gypsum. Product performance depends on the calcination process, fineness, water demand, setting time and any additives. Gypsum binder and ready-mixed formulated plaster should be specified separately according to the intended application. This page covers processed building gypsum rather than natural gypsum rock. Applications • Interior gypsum plaster formulations • Wall and ceiling finishing materials • Decorative moldings and architectural elements • Gypsum-based repair and patching products • Gypsum board and panel manufacturing, subject to process specifications • Other gypsum-based construction products Grade & Specifications Please specify whether gypsum binder or a formulated plaster product is required and identify the intended application. Include requirements for purity, fineness, moisture, water demand and initial and final setting times.

The proposed grade and supporting documentation will be reviewed against your requirements. Packaging & Supply Please state whether bulk shipment or bagged supply is required.
