Physicochemical properties: Sodium persulfate is a white colorless, odorless crystal, or powder with a density of 2.4g/cm 3 , which is decomposed by ethanol and has good stability at room temperature. Often used as a strong oxidant, it can also act as a monomer polymerization initiator. It absorbs little moisture, is easy to store, and is easy to use and safe.

Synonyms: NaPS、SPS、Sodium peroxydisulfate、Sodium peroxydisulfate、Persulfate de sodium、Na2s2o8、Natrium Persulfate、Sodium Per Sulfate、Cas No.7775-27-1、Etching agent、Peroxydisulfuric acid,                 

Disodium peroxodisulfate、Dinatriumperoxodisulfat (German)、Peroxodisulfato de disodio (Spanish); Peroxodisulfate de disodium (French).

Storage: Sodium persulfate is not flammable, but it can help to release odor due to the release of oxygen. When stored, it must be stored in a dry, airtight container, away from direct sunlight and near heat sources. Do not come in contact with reducing substances such as organic matter, iron rust, and trace metals to prevent decomposition and explosion of sodium persulfate. Due to the bleaching and slight corrosive effects of wet sodium persulfate powders and their aqueous solutions, eye, skin and clothing are avoided from direct contact during use.


Polymerization: It is used as initiator for the polymerization of monomers and as a strong oxidizing agent in many application. It has the particular advantage of being almost non-hygroscopic, of having a particularly good storage stability and of being easy and safe to handle.

PCB Etching/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.

Radical Initiator: It is used as a radical initiator for emulsion polymerization reactions and for accelerated curing of low formaldehyde adhesives.

Soil stabilization : Ammonium persulfate is used as a curing agent in chemical grout systems used to stabilize soil near dams, tunnels, and buildings.

Hair Cosmetics: It is used as a bleach, both standalone (particularly in hair cosmetics) and as a detergent component.Sodium Persulfate are safe as used as oxidizing agents in hair colorants and lighteners designed for brief discontinuous use followed by thorough rinsing from the hair and skin.

Oil and Gas Production:

Breaker; Allows a delayed breakdown of the gel in Drilling Muds.Oil fracturing additives,  Drilling Fluid Additives. 

In enhanced oil recovery, persulfates are used "down hole" for gel forming and breaking.

Textiles: De-slurry and bleach - especially for low-temperature bleaching.

Others: It is also used as a soil conditioner and in manufacture of dyestuffs, modification of starch, bleach activator, desizing agent for oxidative desizing, etc.


Ammonium Persulfate crystals, they are used as an alternative to the traditional ferric chloride to produce a cleaner copper etchant solution.
