Application

Descriptions:

• Potassium persulfate (formula is K2S2O8) is also known as potassium peroxydisulfate, molecular weight is 270.32, and decomposition temperature is 100°C.

• Potassium persulfate is white, odorless crystal.

• Potassium persulfate is soluble in water, insoluble in alcohol.

• Potassium persulfate is non-flammable, it is combustion-supporting which due to it can release of oxygen, storage environment must be dry and clean, well-ventilated.

• Potassium persulfate almost does not absorb moisture, it has good stability at room temperature, it is easy to be stored, and it has the advantages of convenience and safety.

• Potassium persulfate has strong oxidizing, it is commonly used as bleaching agents, oxidizing agents, and it can be used as the polymerization initiator.

Uses:

• Potassium persulfate is a suitable initiator for the emulsion or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride etc, and for the emulsion copolymerization of styrene, acrylonitrile, butadiene etc.

• Potassium persulfate is also a kind of oxidizing agent:

• Potassium persulfate is used in cleaning and pickling of metal surfaces.

• Potassium persulfate is used in accelerated curing of low formaldehyde adhesives.

• Potassium persulfate is used in modification of starch, production of binders and coating materials.

• Potassium persulfate is used as desizing agent and bleach activator in textile industry.

• Potassium persulfate is used as an essential component of bleaching formulations for hair dye cosmetics.
