Sodium Sulfide Supplier for Industrial-Grade Na₂S Solutions

As a professional Sodium Sulfide Supplier, we understand that industrial performance depends on consistent quality, controlled purity, and a reliable global supply chain. Sodium Sulfide (Na₂S) is a critical inorganic chemical widely used as a reducing agent and alkaline source in leather processing, mineral flotation, and pulp manufacturing.

Commonly supplied as yellow to red sodium sulphide flakes in hydrated form (Na₂S·9H₂O), this material dissolves easily in water to form strongly alkaline solutions. Selecting an experienced Sodium Sulfide Supplier is essential to ensure process stability, product uniformity, and uninterrupted production.

Key Industrial Applications

Sodium Sulfide is a versatile agent used for its reducing and alkaline properties. As your dedicated Sodium Sulfide Supplier, we cater to the following major sectors, providing complementary chemical solutions for your entire production line.

1. Leather Industry (Tanning & Dehairing)

The leather industry is the largest consumer of Na₂S. It is the primary dehairing agent used in tanneries.

• Function: It breaks down the disulfide bonds in hair keratin, effectively removing hair from hides.
• Benefit: Sourcing high-purity flakes from a trusted Sodium Sulfide Supplier ensures precise control over the tanning process, resulting in softer, higher-quality leather without damaging the grain.

2. Mining & Ore Flotation

In the mining sector, Sodium Sulfide acts as a critical flotation agent, particularly for oxidized lead and copper ores.

• Synergy: It modifies the surface of mineral ores, allowing valuable metals to be separated. In many flotation circuits, it is used alongside pH regulators like Soda Ash to optimize the separation environment.

3. Pulp and Paper Manufacturing

In the Kraft process, Sodium Sulfide is essential for digesting wood pulp.

• Process: It is combined with Caustic Soda to form “white liquor,” which dissolves lignin and separates cellulose fibers to create strong paper products.

4. Chemical Manufacturing & Waste Treatment

It serves as a reducing agent in organic synthesis and is vital for removing heavy metals from wastewater.

• Waste Treatment: While Sodium Sulfide precipitates metals, Hydrogen Peroxide is often used in subsequent stages to reduce COD (Chemical Oxygen Demand) and neutralize sulfur odors.

5. Textile & Detergent Applications

In the textile industry, Sodium Sulfide is used in the application of sulfur dyes.

• Complete Solutions: For the subsequent washing, scouring, and bleaching processes required to finish fabrics, we also supply high-performance surfactants such as LABSA and SLES.

6. Rubber Industry

Na₂S is used in the vulcanization process to improve elasticity.

• Processing: It is often utilized in facilities that also require processing aids and lubricants like PE Wax to ensure smooth manufacturing of rubber goods.
