Salicylic Acid, also known as 2-hydroxybenzoic acid, is a white, crystalline solid. It is used in the production of aspirin, in facial cleansers and acne products, as a preservative in food, and as a wood preservative.
When rubber is exposed to Salicylic Acid, it can suffer from a variety of issues, including discoloration, swelling, cracking, and softening. The rubber can also become brittle, leading to failure. Additionally, when exposed to high concentrations of Salicylic Acid, the rubber can become brittle and swell, which can lead to further failure of the rubber seal.
