- Description:
Product name: Sodium Persulfate
Molecular Formula: Na2S2O8
UN No.: 1505
CAS No.: 7775-27-1
EINECS No.: 231-892-1
- Characteristics:
Sodium persulfate is a white, crystalline, odorless salt. It is used as initiator for the polymerisation 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 as a result of its extremely high purity and of being easy and safe to handle.

- Application:
- Used in the cleaning and acid washing of metal surface.
- Used to accelerate the treatment process of low-concentration formalin adhesive.
- Used as modification agent in the production of starch, also used in adhesive and coating production.
- Used as desizing agent and bleaching activating agent.
- Used as one of the basic ingredients in hair dye, with decoloring action.
- Precautions:
Sodium Persulfate is a kind of non-inflammable product, but it has combustion-supporting action because it can release oxygen, therefore, it should be stored under certain conditions. First, it should be stored in dry and closed container; Second, it should keep away from sunlight, heat sources and moisture; Moreover, some impurities such as defilement, rust, some metals and reducers can cause the decomposition of ammonium persulfate, therefore, these matters should be paid attention to during storage and use. Because the moist ammonium persulfate powder and its aqueous solution have bleaching and slight corrosiveness, the operate should avoid eyes, skins or clothing direct contacting with it.
