Molecular Weight 172.17 g/mol

Gypsum powder is a soft white or grey mineral composed of calcium sulfate dihydrate. It is widely used in construction (as drywall or plaster), agriculture (as a soil conditioner), and various industrial applications. When heated, it loses water and forms Plaster of Paris, which hardens upon rehydration.

Industrial Uses

1.Paints, Coatings & Adhesives

  • Filler and Extender: Gypsum powder is used as an inert filler in paints, coatings, and adhesives to improve texture, enhance durability, and reduce production costs.
  • Surface Smoother: In wall primers and putties, gypsum provides a smooth and uniform surface for better paint adhesion.

2. Energy

  • Flue Gas Desulfurization (FGD): Synthetic gypsum is a byproduct from scrubbers used in coal-fired power plants to reduce SO₂ emissions, later repurposed in construction materials.
  • Thermal Insulation: Used in fireproofing panels and insulation boards in power infrastructure.

3. Lubricants & Automobiles

  • Mold Release Agent: Gypsum is used in foundries and automotive component molds for dimensional stability and heat resistance.
  • Brake Pad Formulation: A minor component in the formulation of friction materials like brake pads.

4. Animal Healthcare

  • Feed Additive: Serves as a calcium and sulfur supplement in animal feed to support bone development and metabolic functions.
  • Litter Conditioner: Used in poultry bedding and livestock areas to reduce ammonia and improve hygiene.

5. Polymers & Resins

  • Filler Material: Used as a filler in thermoplastics and thermosetting resins to reduce cost and enhance dimensional stability.
  • Fire Retardant Additive: Improves fire resistance in composite materials by releasing water vapor on heating.
