Name: Sodium persulfate          

Molecular formula: Na2S2O8

Molecular weight: 238.13

Characteristics:

Sodium 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.

Application:

Sodium persulfate is a suitable initiator for the emulsion or solution polymerization of acrylic monomer, vinyl acetate, vinyl acetate, vinyl chloride etc. and for the emulsion copolymerisation of styrene, acrylonitrile, butadiene etc.. Aps is also a kind of oxidizing agent:

(1) Used in cleaning and picking of metal surface.

(2) Used in accelerated curing of low formaldehyde adhesives.

(3)Used in modification of starch , production of binders and coating materials.

(4) Desizing agent and bleach activer

(5) An essential component of bleaching formulations for hair cosmetics.
