Thiourea Dioxide for dyeing industry
CAS No.: 1758-73-2 M.F: (NH2)2CSO2 M.W. : 108.12 Hazard: 4.2 UN:3341
Properties: Thiourea Dioxide is an odorless and stable compound without oxidizability and reducibility.
Solubility in water 26.7g/l (20℃),PH: 5.0 (saturated aqueous solution).It is very stable even in 20-30℃
aqueous solution, but it decomposes gradually to form sulfinic acid under heat and alkali conditions.
Applications: Thiourea Dioxide is mainly used in dyeing industry,secondly used for organic synthesis in
synthetic fiber industry, as well as an addditive in polymerization,stabilizer for polythene,it has the advantages
of safe handling and storage,high redox potential and efficiency.Eco-friendly and non-pollution.
Storage instructions: Keep Thiourea Dioxide in a cool(max. 25°C), dry and ventilated place. Avoid damp,
insolation and rain. Keep away from oxidizing agents and heat.
Free-flowing white crystalline powder
Conclusion: The Quality of the above said is in conformity with Enterprise Standard
Packaging: 25 kg net kraft paper bag / plastic woven bag, 50kg fiber drum 500 / 1000 kg super bag.
