Potassium perfsulfate is a white crystalline, odourless powder, the
density of 2.477. It can be decomposed about 100 centigrade 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.
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
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).
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment, oxidative degradation of harmful
substances(e. G. Hg)

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.
