    Details

    Potassium persulfate is a white, crystalline, odourless salt. It is used as initiator for the polymerisation of monomers and as a strong oxidizing agent in many applications. It has the particular advantage of being almost non-hygroscopic, of having a particularly good storage stability as a result of its extremely high purity and of being easy and safe to handle.

    Polymerisation: Initiator for the emulsion or solution polymerisation of acrylic monomers, vinyl acetate, vinyl chloride etc. and for the emulsion copolymerisation of styrene, acrylonitrile, butadiene etc.. Dosage: 0.1-0.5% KPS (PPS). Temperature: 75-95°C. In combination with redox systems (ascorbic acid, Rongalit, sulfites or sugar –possibly in combination with heavy metal salts such as Fe 2+ it can also be used for polymerisation reactions carried out at lower- and even at ambient – temperatures. To reduce the residual monomer content, a combination of KPS (PPS) with TBHP-78-AQ is recommended, particularly in cases where redox systems are used.

    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 particularly 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
