Ammonium persulphate

Molecular formula:(NH₄)₂S₂O₈      Molecular weight:228.20

Characteristics:

Ammonium persulfate is a white, crystalline, odourless salt. It is used as initiator for the polymerisation of monomers and as a strong oxidizing agent in many application. 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.
