PHOSPHINE Resistant O-Rings and Seals
PHOSPHINE, also known as phosphorane, is a colorless, highly toxic gas with a garlic-like odor. It is commonly used in the production of semiconductors and other electronics, as well as for fumigation and in some petrochemical applications.
When rubber is exposed to PHOSPHINE, the rubber is at risk of becoming embrittled, discolored, cracked, and swollen. The chemical can also react with the rubber material forming a hard coating that can interfere with the rubber's flexibility. Therefore, it is important to use rubber materials that are resistant to PHOSPHINE in applications where the chemical is present.
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.
