Calcium bisulfite (also known as calcium hydrogen sulfite) is a chemical compound used in a variety of industrial applications, such as water treatment and paper production. It is also used as a preservative and bleaching agent in food production.
When rubber is exposed to calcium bisulfite, it can experience a number of different types of failure, such as discoloration, swelling, and cracking. Additionally, the rubber material can become brittle, resulting in decreased elasticity and the breakdown of the material over time. The chemical can also cause the rubber to corrode and become permeable, leading to the loss of air or water tightness. In extreme cases, the rubber material may break down completely and become unusable.
