MALIC ACID Resistant O-Rings and Seals

Malic acid, also known as hydroxybutanedioic acid, is an organic compound found naturally in many fruits and vegetables. It is commonly used as a food additive for its tart flavor, as well as in cosmetics and pharmaceuticals.

Common types of failures when rubber is exposed to malic acid include cracking, embrittlement, swelling, and discoloration. Malic acid can cause rubber to swell, leading to softening and other deformations. Additionally, malic acid can cause rubber to become brittle, leading to a decrease in its elasticity and strength. Malic acid can also cause rubber to discolor due to its oxidizing properties. Finally, malic acid can cause rubber to become more susceptible to other environmental factors, such as ozone and ultraviolet radiation, resulting in accelerated aging.
