Sodium persulfate
 Molecular
formula: Na2S2O8
Structural formula: 
Molecular weight:238.13
Characteristics:
Sodium 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.

Storage and Handling:
SPS is not combustible but assists combustion of combustible
materials due to release of oxygen. Provided it is stored
under approriate condition. It must be stored dry in closed
containers and protected from direct sunlight, heat and humidity.
Impurities such as dirt, rust or traces of metal and reductants
may cause catalytic decomposition. The product as supplied
or in solution needs to be handled with appropriate care.
The eye, skin and clothes must be protected when working with
SPS. SPS as damp powder or aqueous solution has a bleaching
and slightly corroding effect.
Application of SPS:
SPS is a suitable initiaor for the emulsion or solution polymerisation
of acrylic monomers, vinyl acetate, vinyl chloride etc. and
for the emulsion copolymerisation of styrene, acrylonitrile,
butadiene etc.. SPS is also a kind of oxidizing agent:
(1) Used in cleaning and pickling of metal surfaces.
(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 activator.
(5) An essential component of bleaching formulations for
hair cosmetics.
