Glossy Crystal Anhydrous Thiourea And Urea 99% Ultra Low Moisture 0
Electroplating Grade
Problem: Common thiourea has high moisture content → plating solution decomposes → coating turns black with many pores
Our Solution: Moisture content ≤0.1% → Electrolyte stability increases by 30%
Case Study: PCB factory yield increased from 85% to 96% (with comparison chart)
Pharmaceutical Grade
Critical Control Points:
  • DMF residue <10ppm (HPLC chromatogram provided)
  • Heavy metals <5ppm (conforming to ICH Q3D)
Applications: Synthesis of antibiotic intermediates and contrast agents
Research Grade
Provided Documentation:
  • Batch inspection raw data (downloadable PDF)
  • Typical application literature (Lithium-Sulfur Battery/Corrosion Inhibitor Research)

Applications of Thiourea
1. Metalworking and Surface Treatment
  • Plating additives: Brightener and stabilizer in electroplating solutions for silver, gold, and other precious metals to improve coating gloss and adhesion
  • Metal corrosion inhibitor: Protects metal surfaces during pickling and rust removal processes
2. Ore Flotation and Metallurgy
  • Flotation agent: Collector or inhibitor in metal ore flotation, especially for copper, lead, and zinc sulfide ores
  • Precious metal extraction: Leaching agent for gold and silver extraction, reducing environmental pollution compared to cyanide methods
3. Chemical and Materials Science
  • Resin modification: Improves heat resistance and mechanical properties of phenolic and urea-formaldehyde resins
  • Plastic additives: Functions as antioxidant or stabilizer to extend product lifespan
  • Functional materials: Used in synthesis of materials with special optical, electrical, or magnetic properties
4. Environmental Protection and Resource Recycling
  • Wastewater treatment: Removes heavy metal ions (mercury, cadmium, lead) through stable complex precipitation
  • Exhaust gas purification: Removes sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) from industrial emissions
  • Battery recycling: Extracts valuable metals (cobalt, nickel) from used batteries
5. Medicine and Biotechnology
  • Drug synthesis: Intermediate for antibacterial, antiviral, and anticancer drugs
  • Protein research: Used in protein denaturation and renaturation processes
6. Agriculture and Food Industry
  • Plant growth regulator: Potential to improve crop stress resistance and yield
  • Food preservative: Functions as antioxidant to extend shelf life
7. Photography and Video Technology
  • Developer: Accelerates development reaction and improves image quality in black and white photography
8. Laboratory and Scientific Research
  • Analytical reagent: Detects metal ions (bismuth, antimony) and organic compounds
  • Crystal growth: Regulates crystal morphology and size as solvent or additive
9. New Energy and Sustainable Development
  • Battery technology: Improves charge/discharge performance and cycle life as electrolyte additive
  • Hydrogen energy storage: Shows potential in hydrogen storage material research
10. Other Applications
  • Preservative: Extends service life of industrial products
  • Nanomaterial preparation: Functions as reducing agent or template agent
