AMMONIUM PHOSPHATE Resistant O-Rings and Seals
Ammonium persulfate, also known as ammonium dihydrogen sulfate, is a white, water-soluble solid that is used as an oxidizing agent in many industries. It is used in various processes such as dyeing, electroplating, etching, and manufacturing of cleaning products, cosmetics, and pharmaceuticals.
When rubber is exposed to ammonium persulfate, the rubber material can swell, corrode, and crack. The rubber may become brittle due to a reaction between the sulfuric acid derived from the persulfate and the rubber material. The rubber may also become discolored due to a reaction between the ammonium ions and the rubber material. Additionally, prolonged exposure to ammonium persulfate can result in a decrease in the rubber's mechanical properties such as its elasticity, strength, and tear resistance.
