Industrial Grade Sodium Hydrosulfide

Sodium Hydrosulfide Available in Stock, Industrial Grade Suitable for Multiple Field Production Needs


As a reputable manufacturer with over 10 years of expertise in chemical raw material R&D and supply, we fully understand the critical impact of "raw material stability" on production capacity, cost, and product quality in industrial operations. Today, we are pleased to recommend our core product—Sodium Hydrosulfide (chemical formula: NaHS). With its high purity, low impurities, and consistent batch quality, it has been widely used in mineral processing, chemical synthesis, environmental protection, leather making, and other fields, helping nearly a hundred enterprises reduce costs and improve efficiency.


I. Core Product Information: Precisely Matching Industrial Needs

Sodium Hydrosulfide is an inorganic compound that appears as a white to light yellow crystalline powder (or liquid). It is highly soluble in water, with its aqueous solution being strongly alkaline and reductive. It serves as an important sulfur-containing raw material in industrial production. Our Sodium Hydrosulfide is available in ≥70% (solid) and ≥30% (liquid) concentrations, tailored to your production scenarios. It is used in mineral collection, wastewater treatment, leather depilation, chemical synthesis, laboratory R&D, and pharmaceutical intermediate assistance.


II. Four Core Advantages: Addressing Procurement Pain Points and Ensuring Production Stability

1. Controllable Purity, Extremely Low Impurities, Reducing Production Loss
Utilizing an "ion exchange + low-temperature crystallization" process, we strictly control heavy metal content (Pb, Cd, Hg, etc.) to <0.001% and chlorine content to <0.5%, avoiding issues such as equipment corrosion and substandard product purity caused by impurities.
Each batch of products undergoes third-party testing, with a complete "Quality Inspection Report" provided and traceable data.

2. Ample Stock, Stable Production Capacity, No Supply Interruption Risk
We have our own production line with an annual output of 5,000 tons of Sodium Hydrosulfide, equipped with a 7,000㎡ storage area. Both solid and liquid products are available in stock, with regular orders shipped within 1 day.
We support long-term supply agreements on a monthly or quarterly basis, locking in prices and production capacity to help you plan your production cycle.

3. Customized Services, Adapting to Different Scenario Needs
Form Customization: Available in powder, granular, and liquid (adjustable concentration) forms based on your feeding method.
Packaging Customization: Offered in 25kg/50kg/200kg vacuum-sealed barrels/bags, tanker transportation, etc., meeting hazardous material transportation standards.

4. Safety and Compliance, Ensuring Full Transportation and Storage Protection
Our products are certified with the "Hazardous Chemical Business License" and "Safety Production License." Transportation is handled by professional hazardous material logistics teams, covering 31 provinces and municipalities across the country.
We provide a dedicated "Material Safety Data Sheet (MSDS)," including storage conditions (cool, dry, away from oxidizers) and emergency handling solutions to reduce usage risks.


III. Core Application Fields: Covering Key Links in Multiple Industries

Thanks to its stable performance, our Sodium Hydrosulfide has become an "essential raw material" in the following industries:

Mineral Processing and Metallurgy: Acts as a collector and depressant for sulfide ores (such as chalcopyrite and sphalerite), enhancing mineral adhesion to flotation agents, improving concentrate recovery rates, and reducing mineral processing costs.

Chemical Synthesis Industry: Used in the preparation of intermediates like mercaptans, sulfides, and thiourea. It is a key raw material for synthesizing dyes, pesticides, and rubber additives, with reaction efficiency 15%-20% higher than traditional sulfur sources.

Environmental Treatment Industry: Effectively removes heavy metal ions (e.g., Cu²⁺, Ni²⁺) from industrial wastewater, generating insoluble sulfide precipitates. Also used in flue gas desulfurization, with a desulfurization rate exceeding 98%.

Leather and Paper Industries: Serves as a depilatory agent, gently breaking down keratin proteins in leather to reduce damage to leather fibers. In papermaking, it is used for deinking waste paper, improving pulp whiteness.


IV. Quality and Service Commitment: Ensuring Worry-Free Procurement

Quality Assurance: Unconditional return or replacement if product purity or impurity content does not meet contract agreements, with round-trip shipping costs covered.

Technical Support: Free product application guidance, such as optimal dosing of Sodium Hydrosulfide in mineral processing and pH adjustment solutions in wastewater treatment.

After-Sales Response: 24/7 online customer service, real-time order progress and logistics updates, with solutions provided within 1 hour of issue reporting.
