Magnesium sulfate, also known as Epsom salt, is a common chemical compound used for a variety of industrial and medicinal applications. It is used in manufacturing, as a fertilizer, for water treatment, and in the production of magnesium oxide. It is also used as a dietary supplement for humans and animals, and as an additive in some foods.
When exposed to magnesium sulfate, rubber can suffer from a variety of common failure types. These include cracking and embrittlement of the rubber, swelling, softening, and discolouration. Moreover, rubber can become brittle and fragile when exposed to magnesium sulfate, leading to its eventual failure. The rubber may also become more prone to ozone attack and ultraviolet radiation, leading to further degradation and damage.
