A new environmental-protection agent which can be used in place of sodium hydrosulfite, It has better thermal stability and stronger reducing ability. Operation is simple and effective,transportation and storage are convenient. There is no pollution during the use of thiourea dioxide.
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. 25KG BAGS
