Explore our foundational chemical series exported worldwide with guaranteed certification and optimal purity.
An authoritative breakdown of molecular properties, chemical synthesis, and grades required for global manufacturing.
Sodium Sulfide (Na₂S) is a vital chemical compound that serves as a cornerstone in various heavy industries. In its anhydrous state, it is a yellow-to-red crystalline solid, though it is most commonly supplied in industrial markets as hydrates (typically containing around 60% Na₂S by weight). The chemical reacts dynamically in aqueous solutions, undergoing rapid hydrolysis to form sodium hydrosulfide (NaHS) and sodium hydroxide (NaOH). This reaction generates the sulfide ions essential for applications ranging from mineral flotation to leather depilation.
For international procurement directors, identifying reliable sodium sulfide manufacturers who can deliver optimal chemical concentration without high levels of contaminants (such as iron, which causes unwanted coloration and reactions) is critical. Cheap sodium sulfide solutions do not compromise on purity; rather, they leverage structural scale, high-efficiency synthesis methods, and geographical logistics advantages to lower production costs.
At Shandong Pulisi Chemical Co., Ltd., we control the impurities profile down to parts-per-million (ppm) tolerances. This precise monitoring ensures that the chemical performance remains highly predictable, avoiding unnecessary reagents overheads in down-stream applications.
How global enterprises integrate Na₂S to optimize performance, minimize processing waste, and achieve cost efficiencies.
Widely utilized as a sulfidizing agent in the flotation of copper, lead, and zinc oxide ores. It activates the mineral surfaces, allowing xanthates and other collectors to attach efficiently, maximizing mineral recovery rates in complex geological operations.
Acts as an essential unhairing/dehairing agent in tanneries. The hydrosulfide ions systematically target the disulfide bonds within keratin, allowing for the swift removal of animal hair while preparing the hides for subsequent tanning phases.
Serves as a robust reducing agent for sulfur dyes in textile manufacturing. It renders insoluble sulfur-based dyes soluble in alkaline mediums, enabling uniform dye uptake on cotton, linen, and viscose fabrics.
Facilitates heavy metal removal in wastewater treatment operations. Sulfide ions precipitate toxic heavy metals (such as lead, mercury, and copper) as highly insoluble metal sulfide precipitates, outperforming standard hydroxide precipitation methods.
Used in the Kraft pulping process to selectively dissolve lignin from wood chips. The sulfur active species accelerate pulping kinetics and improve the mechanical strength of the resulting paper fibers.
Functions as a sulfur-donating reagent in organic synthesis, including the production of high-performance engineering plastics like Polyphenylene Sulfide (PPS) and various specialty rubber vulcanizers.
A leading public company dedicated to mining, feed, petrochemical, and pharmaceutical chemicals.
Established in 2006, Shandong Pulisi Chemical Co., Ltd. (Stock Code: 307785) has grown to become a premium supplier of industrial, mining, feed, and pharmaceutical chemicals. Over the past two decades, we have forged strategic partnerships with multiple Fortune Global 500 enterprises, including China National Petroleum Corporation (CNPC) and Saint-Gobain.
The company has passed the rigorous ISO9001:2015 Quality Management System Certification and the German BV Certification. As an Alibaba Demonstration Base and recognized Foreign-Oriented Economic Enterprise, Shandong Pulisi combines advanced chemical synthesis, strict supply chain management, and world-class customer service to help buyers achieve their production targets.
Headquartered in Zibo, Shandong Province, we operate dedicated warehousing and rapid distribution networks at key logistics hubs including Qingdao Port, Tianjin Port, and major inland border ports such as Alashankou and Khorgos to facilitate seamless export logistics.
Unlocking maximum value through automated manufacturing, optimized logistics, and green production structures.
Our manufacturing facility utilizes a Distributed Control System (DCS) to monitor every phase of the sodium sulfide manufacturing process. From raw material intake to final packaging, automation ensures consistent quality and minimizes human error.
We source our raw materials locally through strategic alliances, significantly lowering transport costs and insulating production from market fluctuations. This allows us to offer cheap sodium sulfide without compromising on purity or compliance.
We maintain large-scale storage facilities at major ports like Qingdao and Tianjin. This proximity allows for rapid ship loading, reducing maritime detention risks and cutting delivery lead times down to a fraction of the industry standard.
Transitioning toward carbon-neutral chemistry, zero-emission loops, and advanced derivative synthesis.
As environmental regulations tighten globally, the chemical industry is experiencing a paradigm shift. Shandong Pulisi is actively investing in next-generation green manufacturing pathways. Our technical roadmap focuses on the recovery and reuse of by-product gases, converting hydrogen sulfide (H₂S) emissions back into high-value chemical inputs.
Furthermore, we are developing low-iron, high-solubility sodium sulfide flakes specifically designed for high-end electronics manufacturing and advanced wastewater treatment systems. By improving the physical format of the compound, we reduce dust emissions in customer facilities, promoting a safer working environment and minimizing reagent loss during mixing operations.
Meeting international regulatory frameworks to ensure frictionless customs clearance and supply reliability.
We actively comply with global chemical regulations including EU REACH, K-REACH, and specific custom zone requirements. Our legal and logistics teams ensure that all shipping manifests, safety data sheets (SDS), and chemical registry certifications are completely in order.
All batches undergo third-party testing by leading audit bodies such as SGS. This process verifies chemical purity, iron concentration, water-insoluble matter, and heavy metal limits, ensuring absolute peace of mind for B2B buyers.
Our products are certified under ISO 9001:2015, FAMI-QS (feed safety), Halal, and Kosher standards, allowing us to supply sensitive food processing, pharmaceutical, and livestock feed applications seamlessly.
Essential considerations for sourcing managers looking to mitigate geopolitical risks and freight volatility.
Managing bulk chemical imports requires a comprehensive logistics layout. Fluctuation in ocean freight rates, vessel availability, and customs clearing timelines can disrupt factory operations.
Shandong Pulisi mitigates these risks by establishing localized distribution nodes. We are not just a manufacturer; we are an end-to-end logistics partner. By using our multi-port shipping model, customers can choose to dispatch cargo from Qingdao, Tianjin, or inland border crossings depending on which route offers the lowest freight rates and shortest transport times.
Additionally, our flexible payment methods (T/T, L/C, D/P, O/A) and low-order minimum options allow mid-sized and large enterprises alike to maintain ideal stock reserves, protecting them from sudden local price hikes.
