MANDELIC ACID Resistant O-Rings and Seals

Mandelic acid, also known as ?-hydroxybenzeneacetic acid, is an aromatic alpha hydroxy acid (AHA) derived from benzoic acid. It is used in the production of dyes, perfumes, and pharmaceuticals, as well as a skin-care ingredient in cosmetics and skincare products.

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