What is Ammonium Persulfate used for?
Ammonium Persulfate is a colorless, white or straw-colored,crystalline (sand-like) powder with a mild, unpleasant odor. It is used as a bleaching agent, food preservative, and polymerization inhibitor.
How does Ammonium Persulfate work？
As a source of radicals, Ammonium Persulfate is mainly used as a radical initiator in the polymerization of certain alkenes.
Commercially important polymers prepared using persulfates include styrene-butadiene rubber and polytetrafluoroethylene.
Illustrative of its powerful oxidizing properties, ammonium persulfate is used to etch copper on printed circuit boards as an alternative to ferric chloride solution.
Ammonium persulfate is a standard ingredient in hair bleach.
Persulfates are used as oxidants in organic chemistry.
For example, in the Minisci reaction and Elbs persulfate oxidation

Prior to working with Ammonium Persulfate you should be trained on its proper handling and storage.
AIR, LIGHT, WATER, MOISTURE, CONTAMINATION, and HEAT will cause Ammonium Persulfate to decompose and become unstable.
Ammonium Persulfate reacts violently in solution with IRON;
POWDERED ALUMINUM; and SILVER SALTS.
Ammonium Persulfate will react with COMBUSTIBLE and ORGANIC MATERIAL S (PAPER, GAS and FUELS) to cause fires.
Ammonium Persulfate is not compatible with OXIDIZING AGENTS (such as PERCHL ORATES, PEROXIDES,PERMANGANATES, CHLORATES, NITRATES,CHLORINE, BROMINE and FLUORINE); STRONG ACIDS(such as HYDROCHLORIC, SULFURIC and NITRIC);
STRONG BASES (such as SODIUM HYDROXIDE and POTASSIUM HYDROXIDE); REDUCING AGENTS (such as LITHIUM, SODIUM, ALUMINUM and their HYDRIDES); and HEAVY and POWDERED METALS (such as COPPER,NICKEL and ZINC).
Store in tightly closed containers in a cool, well-ventilated area away from WATER, MOISTURE, LIGHT and HEAT.
