Chromic Acid, also known as Chromium Trioxide, is a corrosive and toxic inorganic compound. It is primarily used in the electroplating industry, such as in chrome plating, as well as in the production of dyes, catalysts, and wood preservatives.
When rubber is exposed to Chromic Acid, it can cause accelerated aging and cracking. The acidic nature of Chromic Acid can cause significant deterioration of the rubber's physical properties, leading to cracking, hardening and loss of elasticity. Chromic Acid can also corrode rubber and metal parts, leading to seal failure, leakage and loss of functionality.
