Properties：
Thiourea Dioxide is an odorless white powder, a stable compound without oxidizability and reducibility. Solubility in water 26.7g/l at 20℃, saturated aqueous solution pH5.0. Thiourea Dioxide is very stable even in 20-30℃ aqueous solution, but it decomposes gradually to form sulfinic acid under heat and alkali conditions.
Application：
Thiourea Dioxide is mainly used in dyeing industry, pulp industry, organic synthesis in synthetic fiber industry, as well as an additive in polymerization, stabilizer for polythene, sensitizer of photographical emulsion and so on. Thiourea Dioxide has the advantages of safe handling and storage, high redox potential and efficiency.
Storage and Handling：
Keep Thiourea Dioxide in a cool, dry and ventilated place. Avoid damp, insolation and rain. Keep away from heat, sparks, flames, alkalis or oxidizing agents.
