Physical and chemical properties

 Sodium persulfate is a white odorless crystal or powder,be decomposed by ethanol,and with good stability at room temperature. Often be used as a strong oxidizer, also be used as a monomer polymerization initiator.  It is almost non- hygroscopic, easy to store , easy to use and safety. 


Sodium persulfate belongs to non- combustble materials,but because it can releases oxygen,so it can help with combustion-supporting effect, and it must be stored in dry and airtight containers to avoid direct sunlight and non-near heat sources. Do not contact with organic matter, rust, small amount of metal and other reducing substances, in order to prevent the decomposition and explosion of sodium persulfate. Due to the bleaching and slight corrosion of wet sodium persulfate powder and its aqueous solution, direct contact with eyes, skin and clothing should be avoided during use. 


Polymerization:Initiators for latex、acrylic monomer polymerization solutions, vinyl acetate, vinyl chloride, and other products, It is also the initiator for the copolymerization of styrene, acrylonitrile, butadiene and other colloids.
Metal Treatment:

Treatment of metal surfaces (e.g. in semiconductor manufacturing: cleaning and etching of printed circuits).Activation of surfaces for copper and aluminum.

Cosmetics:the essential component of a bleaching formula.
desizing agent and bleach-- activator-particularly for cold bleaching.
chemical synthesis; water treatment (decontamination); disinfectant; waste gas treatment; oxidative degradation of harmful substances (e.g. mercury)
