Product Introduction
Product introduction
Sodium Sulfate Anhydrous, also known as Thenardite or Glauber’s salt (anhydrous form), is a white crystalline solid with a purity of up to 99% min. It is highly soluble in water and widely recognized as a cost-effective raw material. This product is extensively used in the detergent industry as a filler, in the glass industry to remove bubbles, in paper and pulp production, and in the textile industry for dyeing and printing. With stable physical and chemical properties, safe and flexible packaging options (25kg, 50kg, or 1000kg jumbo bags), and reliable supply capacity, Sodium Sulfate Anhydrous has become one of the most important bulk inorganic chemicals in the global market.

Application
1.D etergent Industry – Na₂SO₄ is widely used as a filler in powdered detergents, helping to control bulk density, improve flowability, and ensure uniform distribution of active ingredients.
2. Glass Manufacturing – In glass production, Na₂SO₄ acts to remove small air bubbles, prevent scum formation, and enhance clarity and surface quality of the final glass product.
3. Paper and Pulp Production – Na₂SO₄ is applied in the Kraft process as a fluxing agent, supporting the pulping reaction and increasing yield while maintaining pulp quality.
4. Textile Industry – Na₂SO₄ is used in dyeing and printing processes as a leveling agent, ensuring even absorption of dyes and improving color consistency on fabrics.
5.Chemical Industry – Na₂SO₄ serves as an important raw material for producing other sodium compounds, such as sodium sulfide (Na₂S), sodium silicate (Na₂SiO₃), and various specialty chemicals.
