Property:Ammonium 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 particular good storage stability as a result of its extremely high purity and of being easy and safe to handle.


APS is a suitable initiator for the emulsion or solution polymerisation of acrylic monomers, vinyl acetate, vinyl chloride etc. For the emulsion polymerisation of styrene, acrylonitrile, butadiene etc. APS is also a kind of oxidizing agent:

1. Used in cleaning and pickling of metal surfaces.

2. Used in accelerated curing of low formaldehyde adhesives.

3. Used in modification of starch, production of binders and coating materials.

4. Desizing agent and bleach activator.

5. An essential component of bleaching formulations for hair cosmetics.

Packing:Net in 25KG plastic woven bag.
