Sodium Persulphate

1. Product info.

Molecular Formula:     Na2S2O8

Molecular weight:       238.13

Sodium persulfateis 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.

2. Application.
1,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.
2,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.
3,Cosmetics : Essential component of bleaching formulations.
4,Paper : modification of starch,repulping of wet - strength paper.
5,Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of

   Jeans).
6,Others :
   - Chemical synthesis
   - Water treatment(decontamination)
   - Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)
   - Disinfectant
