Peracetic Acid, also known as Peroxyacetic Acid, is a strong organic acid typically used for sterilization and disinfection of surfaces and equipment. It is also used for bleaching, deodorizing, and oxidation in the food, pharmaceutical, and water treatment industries.
When rubber is exposed to peracetic acid, even in small concentrations, it can cause the rubber to become brittle and crack. This can lead to weakened seals, which can fail to hold pressure and cause leaks. Additionally, the acid can cause corrosion and degradation of the rubber. This can lead to decreased elasticity and flexibility, making the rubber more prone to cracking and abrasion. Prolonged exposure to peracetic acid can cause irreversible damage, making it important to ensure rubber components are adequately protected.
