Benzilic Acid is a dicarboxylic acid also known as Benzoic Acid. It is used as an additive in food, in the production of plastics, and in the manufacture of paints, dyes, and inks. It is also used to produce an active ingredient in insecticides.
When rubber is exposed to Benzilic Acid, it can cause the rubber material to degrade rapidly. The rubber may become brittle, swell up, and become distorted. This can significantly reduce the rubber's tensile strength and lead to cracking and tearing of the material. It is also possible for the rubber to become completely dissolved in a concentrated solution of the acid. Natural rubber is less resistant to the acid than synthetic rubbers such as EPDM and Nitrile.
