Shouguang Xinsheng Chemistry Co., Ltd is a professional manufacturer and exporter of Thiourea Dioxide, pulp bleaching agent FAS.
Thiourea Dioxide (TDO or TUD) is also named as Formamidine Sulfinic Acid. Its
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 degrees centigrade),while its PH is 5.0 insaturated solution. TDO appears terrific stable even in 20 -30 degrees centigradesolution, 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.
TDO 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 it is also used in organic synthesization of sensitizing material, and
medicine, medical, spicery materials in fine chemicals, and also can be applied in the
recycling and separating of heavy metals.
