Nitrogen Tetroxide, also known as dinitrogen tetroxide (N2O4), is a colorless, odorless gas that is commonly used in rocket fuel. It is used in the manufacturing of chemicals, in agriculture as a fertilizer, and in healthcare for sterilization.
When rubber is exposed to nitrogen tetroxide, the rubber can become brittle and crack due to an oxidation reaction. The rubber can also become softer and more prone to tearing. Additionally, the rubber can become discolored due to the reaction. The rubber surface can also become sticky due to the reaction, which can lead to dirt and bacteria sticking to the rubber. The rubber can also become more prone to damage due to UV radiation, which can cause further degradation.
