Sodium sulfide, represented by the chemical formula Na₂S, is a key inorganic chemical compound that exhibits a strong alkaline property and acts as a powerful reducing agent. Primarily existing in hydrated forms, the compound is most commonly commercialized as yellow or red flakes containing approximately 60% $Na_2S$, with the remaining balance being water of crystallization ($Na_2S \cdot xH_2O$, where $x$ is typically 5 or 9).
Understanding the molecular interaction of sodium sulfide is crucial for modern industrial processing. As leading ODM (Original Design Manufacturer) suppliers, we synthesize tailored variations of the sodium sulfide formula, adapting the moisture balance, iron content, and physical morphology (flake, granular, or solid) to fit exact process parameters. Our precision engineering ensures optimized solubility profiles, minimal hydrogen sulfide ($H_2S$) off-gassing during storage, and enhanced chemical reactivity.
For applications such as high-grade textile dyeing and leather manufacturing, the presence of iron impurities can result in staining and sub-optimal chemical reactions. We specialize in producing ultra-low iron sodium sulfide (Fe < 10 ppm) to ensure pristine processing outcomes.
How our custom-formulated Sodium Sulfide drives performance across heavy industries worldwide.
| Industrial Field | Function of Sodium Sulfide Formula | Operational Outcome | Critical ODM Parameter |
|---|---|---|---|
| Mining & Metallurgy | Sulfidizing agent for oxide ores (copper, lead, zinc). Depressant in selective flotation circuits. | Enhances bubble attachment to mineral surfaces, boosting extraction yields. | Accurate concentration control, minimal sulfur dioxide release. |
| Tanneries & Leather | Dehairing agent. Breaks disulfide bonds in keratin. | Ensures complete hair removal from animal hides without damaging structural collagen. | Low iron content to prevent hide coloration and staining. |
| Water Treatment | Precipitant for dissolved heavy metals ($Pb^{2+}$, $Cd^{2+}$, $Hg^{2+}$). | Forms highly insoluble metal sulfides for easy mechanical filtration. | High reactivity flakes with fast dissolution curves. |
| Textile & Dyestuffs | Reducing agent for sulfur dyes. | Ensures dye solubility and permanent fiber binding. | Pure formulations ensuring consistent color reproduction. |
In mining flotation operations, our ODM sodium sulfide acts as a highly selective regulator. By modifying the surface potential of copper or zinc sulfides, it enables process engineers to isolate precious materials from silica-rich gangue. In wastewater purification, compared to traditional hydroxide precipitation, sulfide precipitation using our engineered $Na_2S$ formulas achieves significantly lower residual metal concentrations, complying with the most rigorous environmental standards globally.

Our chemical production lines operate under strict international frameworks to guarantee compliance and product purity.
Securing a reliable volume supply of custom-formula sodium sulfide requires more than just reactor vessels. It demands a highly strategic logistics infrastructure capable of transporting class-8 hazardous substances securely across ocean networks and land boundaries.
Shandong Pulisi Chemical has integrated its manufacturing pipelines with regional shipping networks. Our warehouses situated near Qingdao Port and Tianjin Port facilitate rapid transshipment of bulk sea freight. For inland Eurasia transit, we utilize overland freight corridors passing through Alashankou and Khorgos border terminals, enabling direct, temperature-regulated rail freight to clients in Central Asia, Russia, and Central Europe.
We deploy special moisture-barrier container liners and custom palletization designs to guarantee that your sodium sulfide arrives intact and ready for deployment without air contact or atmospheric degradation.
Meeting stringent global criteria for environmental preservation and hazardous material management.
Operating as an international chemical exporter requires full compliance with localized regulatory systems. Shandong Pulisi Chemical adheres strictly to safety and import mandates globally, reducing customs friction for our distribution network.
Our products undergo thorough validation, ensuring compliance with EU REACH / K-REACH directives, GHS labeling regulations, and the UN Recommendations on the Transport of Dangerous Goods. We provide comprehensive safety data sheets (SDS) translated into over 15 regional languages, detailing exact chemical specifications, toxicological dynamics, and containment procedures.
