| Detailed Description of Product |
Name : Ammonium persulfate
Molecular formula: (NH4)2S2O8
Molecular weight: 228.20
Characteristics:
Ammonium 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 application. It has the particular advantage of being almost nonhygroscopic, of having a particularly good storage of stability as a result of its extremely high purity and of being easy and safe to handle.
