PROPIONALDEHYDE Resistant O-Rings and Seals

Propionaldehyde, also known as propanal and propanaldehyde, is a clear, colorless, and flammable liquid with a strong, sweetish odor. It is used in a variety of industries including cosmetics, pharmaceuticals, food and beverage, and chemical manufacturing. It is also used as a solvent and in the production of other chemicals.

Common types of failure when rubber is exposed to propionaldehyde include swelling, cracking, and loss of strength. Rubber becomes more permeable and more brittle when exposed to propionaldehyde, leading to increased permeation of the compound and decreased tensile strength. Exposure to propionaldehyde can also cause rubber to become tacky or discolored, resulting in a decrease in its aesthetic appeal. Additionally, some forms of rubber may become more brittle and crack when exposed to propionaldehyde resulting in a decrease in its mechanical properties.
