Product Description
Product Overview
Sodium Sulphide Yellow Flakes (Na₂S) are high-purity industrial chemicals used extensively in the paper, leather, photographic, and water treatment industries. With a guaranteed 60% minimum sulphide content, these flakes offer exceptional reactivity for chemical and industrial processing.
Applications & Use Cases
Sodium Sulphide is commonly used in: - Sulfitization of tanning extracts in leather processing - As a dechlorinating and desulfurizing agent in chemical manufacturing - Oxygen scavenger in water treatment systems - Bleaching agent in textile and paper mills - Ore flotation and dye manufacture It also plays a role in protecting photographic developers from oxidation and improving oil recovery efficiency.
Chemical Properties
- Total Sulphide (Na₂S): ≥ 60% - Sodium Hydrosulphide (NaHS): ≤ 2.5% - Excess Alkali (NaOH): ≤ 2.0% - Water Insolubles: ≤ 0.20% - Chloride (NaCl) and Sulphate (Na₂SO₄): ≤ 1.00% each - Iron and aluminum compounds: ≤ 0.002% These specs ensure high chemical reliability with low contamination.
Packaging & Handling
Supplied in moisture-resistant 50kg industrial bags, Sodium Sulphide flakes are easy to handle, store, and transport. The uniform flake form allows efficient dosing and application in bulk processing environments.
Export Supply
Manufactured in India and distributed globally, this product meets the needs of international B2B buyers in leather, textile, chemical, and water treatment industries. It is export-ready with compliant packaging and reliable sourcing.

Frequently asked by buyers
Common questions B2B buyers ask before sourcing Yellow Sodium Sulphide Flakes For Industrial, Packaging Type: Bag. Answers compiled from verified sellers' commercial terms and platform data.
Q: What impurity levels are controlled in these Yellow Sodium Sulphide flakes to ensure process reliability?
A: The flakes maintain impurity levels with Sodium Hydrosulphide (NaHS) ≤ 2.5%, Sodium Hydroxide (NaOH) ≤ 2.0%, water insolubles ≤ 0.20%, chloride (NaCl) and sulphate (Na₂SO₄) ≤ 1.00% each, and trace metals (iron, aluminum) ≤ 0.002%, ensuring consistent quality and minimal contamination.
Q: How does the flake form of Sodium Sulphide enhance its industrial usage compared to powder forms?
A: The uniform yellow flakes offer improved handling, accurate dosing, and reduced dust generation compared to powders, making them preferable for bulk industrial processes and safer transportation.
Q: Can these Sodium Sulphide flakes be used in photographic developer processes?
A: Yes, the flakes serve as an oxygen scavenger to protect photographic developers from oxidation, enhancing developer life and performance.
Q: What packaging specifications ensure the product’s integrity during export and storage?
A: The flakes are supplied in moisture-resistant 50kg industrial bags designed for secure handling, moisture protection, and compliance with international export standards.
Q: Which industries benefit most from using 60% purity Yellow Sodium Sulphide flakes?
A: Industries such as leather tanning (for sulfitization), paper and textile manufacturing (for bleaching), water treatment (as an oxygen scavenger and dechlorinating agent), chemical manufacturing, and photographic processing rely heavily on these flakes.
Q: Are the Sodium Sulphide flakes compliant with international industrial standards for export?
A: Yes, manufactured in India with strict quality controls and packaged appropriately, these flakes comply with industrial quality and export standards demanded by global B2B buyers.
