      Thiourea dioxide is a stable compound, a new product that replaces sodium hydrosulfite, and an important intermediate of nitrogen compounds in organic and inorganic chemical industries. It has good stability and unique reducibility. It can be used as a color stripping agent for vat dye dyeing, poor dyeing surfaces, reduction cleaning, silk whitening, plastic stabilizer, and photosensitive material sensitizer. It is widely used in the fields of printing and dyeing, papermaking, polymer materials, fiber industry, chemical pulp, biomass cellulose, pharmaceuticals, polymerization, organic synthesis, inorganic synthesis, and other fields.

Use:

Thiourea dioxide is a new type of environmentally friendly product that replaces insurance powder, with strong reduction, obvious effect, good thermal stability, convenient storage and transportation, and does not contain formaldehyde and APEO, environmental protection and no pollution during use.
1. As an auxiliary agent for textile printing and dyeing, thiourea dioxide is widely used in the dyeing of vat dyes and sulfur dyes, the bleaching of wool silk, the reduction cleaning of disperse dyes, the peeling of direct or reactive dyes with poor dyeing, the cleaning of dyeing vats, etc.
2. Thiourea dioxide as a pulp bleaching agent, used in the paper industry pulp bleaching, waste paper deinking, etc.
3. Other uses: used as catalyst and stabilizer for synthetic resin in the polymer material industry; Thiourea dioxide is also used in fine chemicals such as organic synthesis photosensitive materials, pharmaceuticals, pharmaceuticals, spices and other precious metals.
