Property
Ammonium persulfate is a white, crystalline, odorless salt. It is used as initiator for the polymerization of monomers and as a strong oxidizing agent in many applicati***. It has the particular advantage of being almost non-hygroscopic, of h***ing a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.
