Dinitrogen tetroxide, commonly known as nitrogen tetroxide, is an oxide of nitrogen and is used as a high-temperature oxidizer in rocket propulsion systems. It is also used as an oxidizing agent in chemical synthesis and as a nitrating agent in the production of explosives. Common types of rubber failures when exposed to dinitrogen tetroxide include swelling, cracking, and discoloration. Swelling occurs when the rubber absorbs the nitrogen tetroxide and increases in size. The rubber may also develop tiny cracks and become brittle, leading to cracking. The rubber may also experience discoloration due to the chemical reaction. In addition, the rubber may become more susceptible to other chemicals.
