What is Sodium Sulphate (Na₂SO₄)?
Sodium sulphate (Na₂SO₄) is a highly stable inorganic salt appearing as a white, crystalline powder. It is highly soluble in water and chemically neutral. In the industrial sector, industrial sodium sulphate is predominantly used as a bulk filler in powder detergents, a fining agent in glass manufacturing, and an essential chemical in the Kraft process for pulp and paper production.

How to Choose a Reliable Sodium Sulphate Supplier?
Selecting the right chemical partner is critical for your production stability. Evaluate your wholesale suppliers based on these six essential B2B criteria.
Weifang Changs Chemical
Your trusted partner for high-grade chemical raw materials.
Purity Consistency
Demand a guaranteed minimum purity of 99%. Stable chemical properties are crucial to prevent formulation errors in your manufacturing process.
Packaging Stability
Look for robust, moisture-resistant packaging (such as double-layered jumbo bags) that protects the chemical integrity during long-distance transit.
Production Capacity
Partner with a factory capable of scaling output. Adequate production capacity guarantees your bulk orders are fulfilled without unexpected shortages.
Export Experience
Global logistics expertise ensures smooth customs clearance, proper documentation, and compliance with international shipping regulations.
Core Industrial Applications
Detergent Industry
Used as a bulk filler in powder detergents (often up to 50% of the formulation) to improve flowability, reduce production costs, and adjust the concentration of active ingredients without affecting cleaning power.
Textile Dyeing
Acts as a level dyeing agent. It promotes even dye penetration into cellulose fibers (like cotton) by adjusting the electrolyte concentration in the dye bath, preventing uneven coloring and reducing fabric waste.
Glass Production
Serves as a fining agent in the glass melt. It helps eliminate small air bubbles and prevents scum formation on the molten glass surface, significantly improving the clarity and structural integrity of the final glass product.
Pulp & Paper
Essential in the Kraft pulping process. It makes up for the sulfur lost during the chemical recovery cycle, maintaining the necessary sulfidity levels to break down lignin efficiently.
Chemical Manufacturing
A fundamental raw material used in the synthesis of sodium sulphide, sodium silicate, and other chemical compounds. Its high purity ensures no unwanted side reactions occur.
Transparent Filler Masterbatch
Our ultra-low iron sodium sulphate is utilized to produce transparent plastic filler masterbatches, maintaining the clarity and light transmission of PE/PP plastic films while reducing resin costs.
