Product Description

Description                     
Potassium persulfate is 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.

Storage :
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:
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.
