ANTHRAQUINONE SULPHONIC ACID Resistant O-Rings and Seals
Anthraquinone Sulfonic Acid, also known as AQSA, is a strong acid used mainly in the dyeing and printing industry. It is used as a mordant, a substance that helps bind dyes to fabrics, and is also used in water treatment and as a catalyst in chemical syntheses.
Common types of failures when rubber is exposed to Anthraquinone Sulfonic Acid include swelling, softening, and cracking. Swelling occurs due to the acid attacking the rubber’s molecular bonds, causing it to expand. Softening occurs due to the acid breaking down the rubber’s molecular bonds, making it more pliable. Cracking occurs due to the acid attacking the rubber’s surface, causing it to become brittle and break apart.
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.
