Description
Potassium perfsulfate is a white
crystalline,odourless powder ,the density of 2.**7.It can be
decomposed about **0°C and dissolved in the water not in
ethanol,and has strong oxidation.It is used to produce
detonator,bleacher,oxidant and initiator for the Polymerization.It
has the particular advantage of being almost non-hygroscopic,of
having a good storage stability in normal temperature and of being
easy and safe to handle.

Storage
KPS(PPS) is not combustible but assists
combustion 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
reductants may cause catalytic decomposition.The product as
supplied or in solution needs to be handled with approprate
care.The eye,skin and clothes must be protected when working with
KPS(PPS). KPS(PPS) as damp powder or aqueous solution has a
bleaching and slightly corroding effect.
Application
polymerization : Initiator for the emulsion or solution
Polymerization of acrylic monomers,vinyl acetate,vinyl chloride
etc.and for the emulsion co-polymerization of
styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the
manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and
aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength
paper.
Textile : Desizing agent and bleach activator - particularly for
cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful
substances(e.g.Hg)
- Disinfectant
