ISOPHORONE Resistant O-Rings and Seals
Isopentane and isophorone are both common names for the chemical cyclopentane, an alkane hydrocarbon with a molecular formula of C5H10. It is often used as a propellant, a refrigerant, and as a solvent in various industries.
Rubber seals, gaskets, and other components may fail when exposed to cyclopentane due to the chemical's volatility and low flashpoint. The chemical can cause rubber to become brittle and crack over time, leading to potential leaks and other issues. Additionally, cyclopentane can cause rubber components to swell, which can lead to the rubber losing its shape and the seal becoming ineffective. This is often the result of the chemical's solvating properties, which can cause the rubber to absorb and expand.
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.
