Mo lecular
Formula: K2S2O8
Structural formula:

Molecular weight:270.31
Characteristics:
Potassium persulphate 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:
PPS 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 PPS. PPS as damp powder or aqueous solution has a bleaching
and slightly corroding effect.
Application of SPS:
PPS 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.. PPS
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.
