Commodity:Sodium persulfate
Molecular Formula : Na2S2O8
Molecular weight : 238.13

Description
Sodium persulfate is a white,crystalline,odourless salt.It is used as initiator for the Polymerization of monomers and as a strong oxidizing agent in many applications.It has the particular advantage of being almost non - hygroscopic,of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.
Transportation
Road/Rail transport : GGVS,GGVE,ADR,RID/CLASS 5.1 Sea transport : GGV Sea/IMDG code : CLASS 5.1 Page 5185,UN no.1505
Water hazards class 1(slight water hazard)
All information is given in good faith,but without warranty,since the conditions of use are outside our control. Verification by the user is recommended.Freedom from patent restriction cannot be assumed.
Package
(1) In 25kgs net multiple paper bags with one PE bag inner
(2) In 25kgs net PE bags
(3) In 25kgs net woven bags with two PE bags inner
(4) In 1000kgs net big woven bags with one PE bag inner
The above package is also with a pallet 1000kgs each.
Storage
NPS(SPS) is not combustible but assists combustion materials due to release of oxygen.Provided it is stored under appropriate condition.It must be stored dry in closed containers and protected from direct sunlight,heat and humidity.Impurities such as dirt,rust or traces of metal and reductants may cause catalytic decomposition.The product as supplied or in solution needs to be handled with appropriate care.The eye,skin and clothes must be protected when working with NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect.
Application
Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)
- Disinfectant

High-speed copper plating of welding wire is brown brown liquid, which is used for non electrodeposition of high-speed copper plating film on iron to facilitate wire drawing process. It can make copper ions deposit orderly, make copper deposit compact, and have strong adhesion. At the same time, the complexing agent can also effectively complexe excessive iron ions in the tank solution, so that the tank solution remains stable. The deposition film is golden yellow and pink, which is loved by users. It can be used as immersion or continuous production line. The weight of copper film is 5-20g/m2
