Sodium sulfate decahydrate, also known as Glauber's salt decahydrate, is a chemical compound composed of sodium, sulfate and 10 water molecules. Common uses of sodium sulfate decahydrate include the production of detergents, glass, and paper as well as a food additive.
When rubber is exposed to sodium sulfate decahydrate, it can become brittle and crack due to the corrosive nature of the chemical. Additionally, sodium sulfate decahydrate can also cause the rubber to swell, lose its elasticity, and become discolored, which can lead to leaks and failure of the rubber seal. In addition, prolonged exposure to the chemical can cause the rubber to degrade prematurely, resulting in an even shorter lifespan for the rubber seal.
