Photographic developer, also known as hydroquinone, is a white crystalline powder used in photography to develop and fix photographs. It is also used as a chemical intermediate in the production of dyes and polymers, and as a bleaching agent for wood and textiles.
When rubber is exposed to photographic developer, it can suffer from swelling, cracking, and hardening due to oxidation. The degree of damage to the rubber depends on the concentration of the chemical, the type of rubber, and the length of exposure. Prolonged exposure can cause complete degradation of the rubber.
