MONONITROTOLUENE, 40% & DINITROTOLUENE, 60% Resistant O-Rings and Seals
Mononitrotoluene and Dinitrotoluene, also known as TNT and DNT respectively, are odorless, yellowish-brown crystalline solids with a combined explosive power greater than TNT alone. Mononitrotoluene and Dinitrotoluene are widely used in the manufacture of explosives, dyes, and pharmaceuticals, as well as a precursor for the production of nitroaromatics.
When rubber is exposed to a mixture of Mononitrotoluene and Dinitrotoluene, the rubber can swell, soften, crack, and embrittle due to the breakdown of the rubber's polymer chains. The combination of the two chemicals can also cause discoloration and corrosion due to its reaction with the rubber's additives, leading to a decrease in the rubber's performance characteristics. Additionally, due to the combination of the two chemicals' high nitrating power, the permeability of the rubber can be increased, resulting in reduced mechanical properties.
EPDM (EP, EPR, Ethylene-Propylene Rubber)
EPDM o-rings, or ethylene propylene o-rings, are a family of synthetic elastomers with lower cost steam and chemical resistance, particularly for applications involving solvents, acids and other mild chemicals. Marco Rubber has the world’s largest inventory network of EPDM o-rings and made on demand custom manufacturing often without tooling fees, so the EPDM o-rings you need are always available. Whether it’s for water systems, braking systems, medical, pharmaceutical, food or dairy use, you can count on Marco Rubber to deliver your o-rings fast and efficiently.
