Product Description:
Potassium persulfate

Molecular formula:K2S2O8

Structural formula:

Molecular weight:270.31

Potassium 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:
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 PPS:
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.
