ETHANAL Resistant O-Rings and Seals
ETHANAL, also known as Acetaldehyde, is a colorless and flammable chemical used in the production of plastics, resins and adhesives. It is also used as a flavoring agent and preservative in the food and beverage industry. Common uses for this chemical include being used as a solvent for paints, varnishes and lacquers, and as a fuel for industrial and consumer products.
When rubber is exposed to ETHANAL, it can suffer from hardening, cracking, and discoloration. Hardening occurs when the chemical reacts with the rubber, causing it to become rigid and brittle. Cracking can occur when the chemical penetrates the rubber, causing it to become weak and break apart. Discoloration can also occur as a result of the chemical's reaction with the rubber.
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.
