برگه اطلاعات فنی کالا TDS
- Ammonium persulfate is a white, crystalline, odourless salt consisting of
- technically pure ammonium peroxodisulfate. It is used as an initiator (source
- of free radicals) for the polymerisation of monomers and as a strong
- oxidizing agent in many applications. It has the particular advantage of having a good storage stability as a result of its extremely high purity and of being easy and safe to handle. Due to its hygroscopic character APS tends to lumping, expecially in humid atmosphere and can be optionally supplied with an addition of silicic acid.
- Uses
- Polymerization initiator, depolymerization in starch modification, and hair bleach formulations
- 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% APS. Temperature:
- 75-95°C. In combination with redox systems (ascorbic acid, Rongalit,
- sulfites or sugar - possibly in combination with heavy metal salts such as
- Fe2+ 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 APS with TBHP-70-AQ is recommended,
- particularly in cases where redox systems are used.
- Cosmetics: Essential component of bleaching formulations.
- Textile: Desizing agent and bleach activator - particularly for cold bleaching.
- Others:
- Chemical synthesis
- Water treatment (decontamination)
- Waste gas treatment, oxidative degradation of harmful substances e.g. Hg)
