Industrial Grade Thiourea: Fine Chemical & New Material Applications
Special Chelating Agent for Precious Metal Extraction
In hydrometallurgy of gold and silver, thiourea serves as an environmentally friendly leaching agent alternative to cyanide. It selectively dissolves precious metals with high efficiency while reducing environmental risks and improving resource recovery rates.
Advanced Resin Synthesis Modifier
In the synthesis of polymer materials such as epoxy and polyurethane resins, thiourea acts as a cross-linking promoter and performance enhancer, significantly improving thermal resistance, mechanical strength, and chemical stability of the final products.
Precision Additive for Specialized Electroplating
In precision electronic component electroplating, thiourea functions as an efficient brightener and leveling agent. It effectively controls plating layer crystalline grain size, achieving micron-level uniform coating distribution to meet high-precision electronic manufacturing requirements.
