We are offering high quality sodium persulfate.Descriptionsodium persulfate is the inorganic compound with the formula na2s2o8. It is the sodium salt of persulfate (also called peroxydisulfate), an oxidizer. It is a white solid that dissolves in water. It is almost non-hygroscopic and has good shelf-life. sodium persulfate is a white crystal without odor, which are often used as a strong oxidizer or monomer polymerization initiator. It hardly absorbs moisture. Due to its extremely high pureness and stability, it can be stored easily. Besides, it also features in simple and safe usage, etc. applicationsodium persulfate is but only an initiator for latex or acrylic monomer polymer fluid, vinyl acetate or chloroethylene, etc. But also an initiator for the copolymerization of cinnamene, acrylonitrile, butadiene and other colloids. It is often used as a strong oxidizer and has the following usages:(1) use while rinsing or cleaning the surface of metal with acid;(2) accelerate the processing procedure of low concentration formalin binder;(3) it is used as a regulator while producing amylum and applied to the production of binder or paint;(4) it is used as desizing agent or active bleaching agent;(5)it is a principal ingredient of hair dye with discoloring function
