Fumaric acid, also known as trans-butenedioic acid, is a common dicarboxylic acid. It is widely used in the food, pharmaceutical, and chemical industries. Common uses for fumaric acid include flavoring food and beverages, as a preservative, and in the manufacture of polyester resins.
Common types of failures when rubber is exposed to fumaric acid include hardening, cracking, and discoloration. Prolonged exposure to fumaric acid can lead to the rubber hardening and becoming brittle, resulting in eventual cracking and failure. Fumaric acid can also cause the rubber to discolor, leading to discoloration of the material. Additionally, fumaric acid may cause the rubber to swell, leading to eventual breakdown and loss of shape.
