Sodium Bisulfite, also known as Sodium Hydrosulfite, is an inorganic compound most commonly used as a preservative, bleaching agent, and dechlorinating agent. It is widely used in food, paper, and textile industries.
When rubber is exposed to Sodium Bisulfite, the rubber can become brittle and degrade over time. This can lead to failure of the rubber seal, resulting in leaks and breaks. Additionally, the rubber material may become discolored or swell up when exposed to Sodium Bisulfite, both of which can cause the seal to be ineffective.
