Molecular formula(NH4)2S208

Synonyms Ammonium Peroxydisulfate

CAS#7727-54-0

Summary of performanceAmmonium 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 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.

Application
(1) Ammonium Persulfate is a suitable initiator for emulsion or solution polymerization of acrylic monomers, vinyl acetate, vinyl chloride etc.
(2) For emulsion copolymerization of styrene, acrylonitrile, butadiene etc. It is also a kind of oxidizing agent, used in cleaning and pickling of metal surface, accelerated curing of low formaldehyde adhesives and modification of starch, production of binders and coating materials, also can be used as desizing agent and bleach activator.
(3) It is an essential component of bleaching formulations for hair cosmetics.
