Ammonium persulfate is widely used as an oxidizing agent in various industrial and laboratory applications. In the polymer industry, it serves as an initiator for the polymerization of monomers like acrylonitrile, vinyl acetate, and styrene, facilitating the production of plastics, resins, and synthetic rubbers. It is also employed in the etching of printed circuit boards (PCBs) in the electronics industry, where it helps remove copper layers to create precise circuit patterns. In hair care products, it is used as a bleaching agent to lighten hair color. Additionally, ammonium persulfate finds application in water treatment processes for breaking down organic contaminants and in cleaning agents for removing stains and deposits. Its strong oxidizing properties make it a valuable component in chemical synthesis and surface preparation processes.
