Thiourea Dioxide
THIOUREA DIOXIDE is a reducing agent for use in reduction clearing, dye-stripping and general textile equipment cleaning.
Thiourea dioxide (TDO or TUD) is also named as Formamidine sulfinic acid/FAS. It’s appearance is white crystal powder. Thiourea Dioxide is a stable compound with no strong reducing and oxidizing ability, and its dissolvability is 26.7g/l (20°C), while its PH is 5.0 in saturated solution. Thiourea Dioxide(TDO or TUD) appears terrific stable even in 20°C-30°C solution, but when it is under heat or catalysesing by alkali, it decomposes gradually to produce sulfoxylic acid through formamidine sulfinic acid to exhibit a reducing action.
Thiourea Dioxide can also be used in paper industry as deinking and bleaching agent to substitute Sodium Hydrosulfite.
Thiourea Dioxide (TDO or TUD) is a new kind of reducing agent that used as exchange of sodium hydrosulfite. It is widely used in textile and paper making industry. This product is also used in leather processing industry, paper, pulp and board industry, photographic industry, bleaching and reducing agents. This product is also a component of decolorisation agents. In macromolecule material industry, it is used as catalysis agent and stabilizer of resinic producing, and ii is also used in organic synthesization of sensitizing material, and medicine, medical, spicery material in fine chemicals, and also can be applied in the recycling and separating of heavy metals.
