Maleic anhydride, also known as cis-butenedioic anhydride, is an organic compound used in the manufacture of unsaturated polyester resins and other industrial products such as lubricants, adhesives, and corrosion inhibitors. It is also used as a food additive, preservative, and flavor enhancer.
Common types of failures when rubber is exposed to maleic anhydride include cracking, swelling, embrittlement, and accelerated aging. Maleic anhydride can cause rubber to swell, leading to cracking, softening, and other deformations. Additionally, maleic anhydride can cause rubber to become brittle, leading to a decrease in its elasticity and strength. Maleic anhydride can also cause rubber to become more susceptible to other environmental factors, such as ozone and ultraviolet radiation, resulting in accelerated aging.
