Physical and chemical properties: Ammonium persulfate is a kind of white odorless single crystal, density 1.98, completely decompose at 120°C, completely dry can be kept for a long time and it does not decompose, not moisture absorption, but after moisture absorption gradually decompose oxygen and ozone. Contact with organic matter, combustibles or oxides easily burns and fuels the fire. Soluble in water and decompose by heat. Contact with metal decomposition, strong oxidation, can be used as a chemical reagent, oxidant, bleaching agent, deodorizer, monomer polymerization initiator. It also has the advantages of convenient use and safety.

Main Uses:

For the manufacture of persulfate.

For the manufacture of Aniline dye and weng dyestuff oxidation hair color agent.

Used for the treatment of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits), activation of copper and aluminum surfaces.

Used in battery industry.

Used as initiator of polymer polymerization in organic synthesis industry.

Used in film development, fixing agent;Widely used in waste liquid treatment.

Decolorization and bleaching of oil, washing and deodorization of decaying yeast, ripening agent of wheat.

An additive used in the fracturing of oil Wells.

Polymerization: latex or acrylic monomer polymerization solution, vinyl acetate, vinyl chloride and other products of the initiator, but also styrene, propylene, butadiene emulsion copolymerization of the initiator.

Cosmetics: The main ingredient in bleaching formulations.

Textiles: desizing agents and bleaching agents - especially for low temperature bleaching.

Others: chemical synthesis; Water treatment purification; Waste gas treatment, oxidative degradation of hazardous substances (e.g. Mercury); Disinfectant; Paper (low temperature bleached especially in pulping).

Product specification: Assay ≥98.5%

Precautions for storage and use：

Ammonium persulfate is a non-flammable product, but it has combustion-supporting effect because it can release oxygen, so it must be stored under certain conditions.Must be stored in dry, airtight container first, should avoid direct sunlight, heat source, damp and other adverse factors next.In addition, some impurities such as dirt, rust, a small amount of metal and reducing agents may cause the decomposition of ammonium persulfate, in the storage and use of the process must also be paid attention to.Direct contact with the eyes, skin and clothing should be avoided during use because the wet ammonium persulfate powder and its aqueous solution are bleaching and slightly corrosive.
