Global Industry Trends of Potassium Persulphate (K₂S₂O₈)

The potassium persulphate market, driven by demands in the electronics, water treatment, and polymer sectors, is witnessing a steady CAGR of 4.0% (2022-2027) [Markets & Markets]. Advanced R&D into green oxidation processes, environmental legislations on effluent discharge, and higher technical requirements for IC and PCB manufacturing, further guarantee dynamic market growth.
Latest innovations focus on safe storage & transport, high-activity grades for fine chemicals, and eco-friendly applications. Stricter GHS/REACH compliance supports wider global trade, while cost-effective supply chains position China as a top exporter of potassium persulphate.

Applications & Use Cases of Potassium Persulphate

• Polymer Industry: Essential as a free-radical initiator in emulsion and solution polymerizations (e.g., SBR, PVC, Acrylates).
• Electronics Manufacturing: Used in the etching of printed circuit boards (PCB), formation of micro-vias, and as a cleaning agent for electronic components.
• Water Treatment: Decomposition generates active oxygen radicals which effectively oxidize organic contaminants, making it vital for industrial and municipal wastewater applications [Water Research, ScienceDirect].
• Textile & Cosmetics: Bleaching and hair-dye formulations, disinfection, and garment finish processes.
• Laboratory & R&D: Analytical grades of potassium persulphate act as strong oxidizing agents in volumetric analysis and chemical synthesis.
• Mining & Soil Remediation: Used for in-situ chemical oxidation (ISCO) to treat contaminated soils and groundwater.
• Others: Photoengraving, decolorizing, and enzyme-free polymerization initiations.

1. What is the typical purity of potassium persulphate supplied by HEBEI FIZA TECHNOLOGY CO., LTD.?

Our typical assay is ≥99.5% (active substance as K₂S₂O₈), which consistently exceeds most national and international standards.

2. Are there specific storage and stability requirements for this product?

Potassium persulphate should be stored in a cool, dry, well-ventilated area, in tightly closed original packaging, away from reducing agents, combustible materials, and direct sunlight to prevent decomposition.

3. How does potassium persulphate compare with ammonium and sodium persulphate?

While all three are potent oxidizers, potassium persulphate is less hygroscopic and offers higher thermal stability versus ammonium persulphate. Its lower solubility can be an advantage in controlled-release processes.

4. What is the recommended packaging and handling standard?

Typically supplied in 25 kg PE-lined fiber drums, UN-approved bags, or customized safe packages. Always follow GHS/REACH and local transport regulations. Use adequate PPE and consult the potassium persulphate SDS.

5. Is your product certified for food, medical or cosmetic use?

For industrial grades, our potassium persulphate conforms to relevant ISO/REACH certifications. For food or cosmetic uses, please specify regulatory and purity requirements at the inquiry stage.

6. What is the molecular weight and key chemical properties?

Molecular weight: 270.32 g/mol; Key properties: strong oxidizer, decomposes with heat/reducing agents, freely soluble in water, releasing active oxygen radicals.

7. Does FIZA offer support with regulatory compliance, like REACH, SDS, or shipping documents?

Absolutely. We provide full documentation including potassium persulfate SDS, REACH and ISO certificates, and detailed COAs. Our logistics team ensures safe shipping globally, per IMDG/IATA standards.
