METHYL ETHYL KETONE Resistant O-Rings and Seals
Methyl ethyl ketone (MEK) is a colorless, volatile, flammable liquid with a sharp, sweet odor. It is commonly used as a solvent in the production of paints, varnishes, pharmaceuticals, and adhesives. It is also used in the manufacture of rubber products, as a degreaser, and in the production of various chemicals.
When rubber is exposed to MEK, the most common types of failures are swelling, softening, and cracking. Swelling can cause the rubber to stretch and deform, which affects its ability to seal properly. Softening may cause the rubber to become brittle and crack, resulting in leakage. Finally, cracking can occur due to embrittlement, which is caused by the chemical reaction of the rubber with the MEK.
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.
