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.
