CITRIC ACID is a weak organic acid found naturally in citrus fruits and widely used as a food preservative, flavor enhancer and cleaning agent. Common applications include food and beverage processing, pharmaceuticals, and cosmetics.
When rubber is exposed to CITRIC ACID, the rubber can become discolored due to the acid's corrosive properties. The rubber can also become brittle and crack, leading to poor sealing performance and potential failure of the rubber part. Additionally, the acid can cause the rubber to swell and distort, resulting in the loss of sealing performance. In some cases, the acid can cause the rubber to degrade prematurely due to accelerated oxidation, as well as surface damage due to the acid's reactive nature.
