1. used as desizing agent and bleaching activating agent.
2. used in oxidation degradation of harmful matters in water pool and closed recirculated water system.
3.Used as modification agent in the production of starch, also used in adhesive and coating production.
4. used in the oxidation of branched chain, the hydroxyl oxidation of alcohol and aromatic compounds.
5. used as one of the basic ingredients in hair dye, with decoloring action.
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.
Packing: 25Kg plastic woven bag, 25Kg PE bag.
