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.
Fluorosilicone o-rings are a hybrid of silicone and FKM resulting in great jet fuel resistance with high and low temperature performance. Also widely used in semiconductor Ashing equipment with strong resistance to oxygen plasma, FVMQ fluorosilicone o-rings also feature excellent flexibility, compression resistance, aging and sunlight resistance, and overall wide range of basic chemical resistance.
