thiourea dioxide, dyes,thiourea dioxide,sodium hydrosulfite,bleach,
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.

sodium percarbonate, detergent,cleaning powder,
It is a new oxygen bleaching agent with a common name of solid hydrogen peroxide, it is an addition compound of sodium carbonate and hydrogen peroxide. Percarbonate has an active available oxygen content which is equivalent to around 14.5% H2O2. It breaks down to oxygen, water and sodium carbonate upon decomposition. It's an environmentally safe bleaching agent.

furfural, furfural,chemical raw materila,
It can be used lubricating oil refining, furfuryl alcohol production by hydrogenation, making several organic chemical products, such as medicine pesticide. It is utilized as a solvent in petroleum industry.
It is transparent liquid with light yellow to amber and odor of bitter almond. Its color gradually become deep color until to brown in storage procedure. It is produced from agricultural wastes that contain pentosans, complex carbohydrates present within the cellulose in many woody plant tissues. Theoretically, almost any pentosan containing material or combination of materials can be used for the production of furfural.
