Summary of performance
Sodium persulfate is a white tasteless crystal, or powder, broken down by ethanol, stable at room temperature. It is often used as a strong oxidant and also as a monomer polymerization initiator. It absorbs little moisture, is easy to store, easy to use, and safe.

(2) net weight 25kg PE bag
(3) net weight 500kg woven bag
(4) net weight 1000kg woven bag

Storage
Sodium persulfate is a non-flammable, but it can release oxygen and play a role of combustion promoter. During storage, it must be stored in a dry, airtight container to avoid direct sunlight and near heat source. Do not contact with reduced substances such as organic matter and rust, a small amount of metal, in order to cause Sodium persulfate decomposition, explosion. Because damp Sodium persulfate and its aqueous solution have bleached and slightly corrosive effects, avoid direct contact with eyes, skin, and clothing during use.

Application

Environmental remediation agents: contaminated soil remediation, water treatment (wastewater purification); Waste gas treatment, oxidative degradation of harmful substances (e.g. mercury).
Polymerization: the initiator of latex or acrylic monomer polymerization solution, vinyl acetate, vinyl chloride and other products, but also styrene, acrylonitrile, butadiene and other colloidal copolymerization initiator.
Metal treatment: cleaning and pickling of metal surfaces (e.g., in semiconductor manufacturing: cleaning and etching of printed circuits). Activation of copper and aluminum surfaces.
Used to speed up the processing of low concentration formalin adhesive.
A modifier used in the production of starch and used as a desorption agent in the production of adhesives and coatings
Cosmetics: essential ingredient in bleaching formulations.
Textiles: Depulsing agents and bleaches - especially for low temperature bleaching.
Hair dye: It is one of the basic components of hair dye and plays a decolorizing role.
Others: chemical synthesis; Disinfectant; Water treatment, purification and disinfection; Waste gas treatment; Oxidative degradation of hazardous substances (e.g. mercury); Paper (low temperature bleaching especially in pulping); Water-reducing agent for mixing suspected soil; In petroleum exploitation, used for fracturing fluid of oil well broken glue agent.
