Potassium Persulfate
Molecular
formula: K2S2O8
Molecular
weight: 270.31
Characteristics:
Potassium persulfate is a white, crystalline, odorless salt. It is used as
initiator for the polymerization of monomers and as a strong oxidizing agent
in much application. It has the particular advantage of being almost non-hygroscopic,
of having 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 appropriate 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 reducing
agent 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 initiator for the emulsion or solution polymerization 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) desize agent and bleach activator.
(5) An essential component of bleaching formulations for hair cosmetics.
