Potassium persulfate is also known as potassium pyrosulfate, potassium salt, and oxidizing salt. It is a strong oxidizing agent and is commonly used in water treatment, wastewater treatment, bleaching, and etching.
When rubber is exposed to potassium persulfate, the rubber can become brittle and begin to crack due to the effects of oxidation. Additionally, the chemical can cause the rubber to swell, which can lead to deformation and a decrease in elasticity. In extreme cases, exposure to potassium persulfate can cause the rubber to break into pieces.
