Picric acid, also known as trinitrophenol, is an acidic compound that is used in manufacturing dyes, explosives, and drugs. It is also used as an antiseptic and in the production of certain acids.
When rubber is exposed to picric acid, it can become brittle and prone to cracking. The acid can corrode the rubber, leading to the loss of elasticity and causing the rubber to become hard and brittle. Additionally, picric acid can cause rubber to become discolored and swell, leading to seal failure and leakage.
