ASTM FUEL C, also known as 2,4-dinitrotoluene, is a common industrial chemical used in the production of dyes, plastics, and rubber products. It is also used in the production of nitrocellulose, which is used as a lacquer in the printing industry. Common uses include the production of propellants, explosives, and as an additive in gasoline.
When rubber is exposed to ASTM FUEL C, the rubber may become brittle and crack due to the presence of the nitro group in the compound. The rubber may also swell, causing it to lose its elasticity and tear easily. In addition, the chemical may leach into the rubber, causing discoloration and further weakening the rubber.
