Application

Descriptions:

• Sodium persulfate is a white crystal without odor.

• Sodium persulfate is often used as initiator for the polymerization of monomers and as a strong oxidizing agent in many applications.

• Sodium persulfate has the particular advantage of being almost non-hygroscopic due to its extremely high pureness and stability.

Uses:

• Sodium persulfate is a suitable initiator for the emulsion or solution polymerization of acrylic monomer, vinyl acetate, vinyl acetate, vinyl chloride etc. 

• Sodium persulfate is also an initiator for the copolymerization of cinnamene, acrylonitrile, butadiene and other colloids.

• Sodium persulfate can be used for the treatment of metal surfaces, activation of copper and aluminum surfaces.

• Sodium persulfate accelerates the processing procedure of low concentration formalin binder.

• Sodium persulfate is used as a regulator while producing amylum and applied to the production of binder or paint.

• Sodium persulfate is used as desizing agent or active bleaching agent.

• Sodium persulfate is a principal ingredient of hair dye with discoloring function.
