Ferric persulfate, also known as ferric sulfate, is a chemical compound mainly used as an oxidizing agent in many industrial processes such as water treatment and paper production. It is also used in the production of dyes, inks, and pigments, as well as for the treatment of wastewater. Common types of failures when rubber is exposed to ferric persulfate include cracking and discoloration, as well as swelling and softening of the rubber due to the highly corrosive nature of the chemical. Additionally, the chemical can cause rubber to become brittle and break down over time.
