Diethyl Sulfate, also known as DESULF, is a sulfur-based ester which is commonly used as a reagent in organic syntheses. Common uses of DESULF include the production of pharmaceuticals, fragrances, and cosmetics.
When rubber components are exposed to DESULF, the rubber can become brittle and brittle-like. This can lead to a decrease in tensile strength, tear strength, and elongation. Additionally, the rubber can become more susceptible to cracking and splitting, leading to a decrease in sealing capabilities. Over time, the rubber can also become discolored and brittle due to the presence of DESULF, resulting in a decrease in reliability.
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.
