ACETALDEHYDE Resistant O-Rings and Seals
Acetaldehyde, also known as ethanal, is a colorless, flammable liquid with a distinct odor. It is most commonly used in the production of acetic acid, which is used in the manufacture of food and beverages, plastic, and in the production of vinyl acetate. It is also used in the manufacture of perfumes, dyes, and medicines.
When rubber is exposed to acetaldehyde, it can suffer from a range of issues, including cracking, discoloration, and corrosion. The rubber can also become brittle and prone to failure due to the chemical’s corrosive nature. In addition, acetaldehyde can cause the rubber to swell, leading to an increase in friction and a decrease in the rubber’s ability to seal properly.
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.
