Sodium sulfate, also known as Glauber's salt, is a chemical compound composed of sodium and sulfate ions. Common uses of sodium sulfate include the production of detergents, glass, and paper as well as a food additive.
When rubber is exposed to sodium sulfate, it can become brittle and crack due to the corrosive nature of the chemical. Additionally, sodium sulfate can also cause the rubber to swell, lose its elasticity, and become discolored, which can lead to leaks and failure of the rubber seal.
