Sodium chloride, also known as table salt, is a chemical compound that is commonly used in food, water treatment, and cleaning products. Common uses for sodium chloride include seasoning food, treating water, and cleaning surfaces.
When rubber is exposed to sodium chloride, it can cause the rubber to become brittle, crack, and discolor. This type of failure is caused by the chemical reaction that occurs between the sodium chloride and the rubber, resulting in the rubber becoming weakened over time. Additionally, the rubber may swell due to the chemical reaction, which can lead to cracking and eventual failure. In extreme cases, the rubber may become brittle enough to break apart.
