Sodium bisulfate, also known as sodium hydrogen sulfate, is an acid salt commonly used as an industrial cleaning and sanitation agent. It can be found in a variety of products including detergents, cosmetics, and food preservatives. It is also used to control pH levels in swimming pools and as an antacid.
When rubber is exposed to sodium bisulfate, it can cause a range of failures including discoloration, swelling, cracking, and decreased elasticity. Over time, the chemical can slowly degrade the rubber, leading to further physical damage. The longer the rubber is exposed to the chemical, the worse the damage will be.
