SULFOLANE Resistant O-Rings and Seals
Sulfolane is a chemical compound also known as sulfonyl methane or tetramethylene sulfone. It is widely used as a solvent and as a raw material in the production of a variety of chemicals such as dyes, plastics, and pharmaceuticals. It is also used as a fuel additive in some automobile engines.
When rubber is exposed to sulfolane, it can cause the rubber to become brittle and crack due to the chemical's corrosive properties. In addition, the rubber may experience swelling, shrinkage, and discoloration. Other potential issues include the rubber developing a tacky surface, becoming stiffer, and exhibiting poor flexibility.
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.
