application
| Item | Industry | Application Description |
| Polymerization | Plastics and Rubber | Ammonium, Potassium and Sodium Persulfates are used as initiators for emulsion polymerization reactions in the preparation of acrylics, polyvinyl chlorides, polystyrenes and neoprene. They are used as polymerization initiators in the manufacture of synthetic rubber (styrene butadiene and isoprene) for automobil and truck tires. Persulfate initiation is used to prepare latex polymers for paints, coatings and carpet backing. |
| Structural Materials | Persulfates are used as initiators in polymeric concrete formulations. | |
| Inorganic Chemicals and Minerals | Persulfates are also initiators for the polymeric coating of graphite filaments. | |
| Soil Stabilization | Ammonium Persulfate is used as a curing agent in chemical grout systems used to stabilize soil near dams, tunnels and buildings. | |
| Oxidation | Surface Preparation | The oxidation power of persulfates is used to clean and microetch a variety of printed circuit board substrates. Persulfates are important oxidants in plating and coating processes. They are also etchants for nickel titanium and zink alloys. Persulfates are used to clean and mill aluminum, brass, copper and many other metal surfaces prior to plating or adhesive bonding. Persulfates are used to clean and activate carbon and charcoal before and after their use as absorbents. |
| Cosmetics | The cosmetic industry has developed formulations which use persulfates to boost hair bleaching performance. | |
| Organic Synthesis | Persulfates are oxidizing agents in the preparation of aldehydes, ketones, carboxylic acids, quinones and a variety of other compounds. The pharmaceutical industry uses sodium persulfate as a reagent in the preparation of antibiotics. | |
| Other Applications | Adhesive | Persulfates are used in the preparation of adhesive films and metal bonding adhesives. |
| Gas and Oil Production | Persulfate can be used for gel formation and gel breaking under oil drilling to enhance oil recovery | |
| Ink, Pigment and Dispersants | Persulfates are used to graft substrates to polymers (for example: carbon black to sodium acrylate.) Persulfates are used in the preparation of dispersants for ink jetting and toner formulations. | |
| Mining | Persulfate can be used in nickel cobalt separation process. | |
| Photography | Persulfates are used in many photographic applications, including bleaching solutions, solution regeneration, equipment cleaning and waste water treatment. | |
| Pulp and Paper | Persulfate are used in the sizing of paper, preparation of binders and coatings, and production of special papers. And activated alkali metal persulfate effectively repupls neutral/alkaline wet-strength broke and decolorizes dyes and optical brightener. | |
| Textiles | Ammonium and Sodium Persulfates are used in the desizing and bleaching of textiles and the devellopment of dyestuffs. | |
| Swimming Pools and Water Treatment | Oxidative degradatin of noxious substances (halogenated hydrocarbons cyanides, sulphur compounds etc.); decontamination and deodorization (e.g. cooling, washing closed circuit process water); decontamination without chlorine for swimming pool water. | |
| Environmental | Persulfates are very strong oxidants, have excellent shelf life when stored properly, and are economical to use. These properties make persulfates suitable for a variety of environmental applications, such as soil remediation and wastewater/groundwater cleanup. Gas scrubber with oxidative degradation of harmful substances (e.g. elimination of Hg in sewage sludge incineration) Oxidative elimination of foul smelling/toxic gas compounds (e.g. CS2, H2S) from process air. |
