ETHYLENE OXIDE Resistant O-Rings and Seals
Ethylene oxide (also known as oxirane, ethylene epoxide, or ethylene glycol oxide) is a colorless, flammable gas with a sweet odor. It is commonly used in the manufacturing of other chemicals, such as ethylene glycol, ethylene glycol ethers, ethylene glycol esters, and ethylene glycol amines. It is also used as a sterilant in the medical and food processing industries.
When rubber is exposed to ethylene oxide, it may cause swelling, cracking, embrittlement, and crazing. High concentrations of ethylene oxide may also cause permanent changes in the structure of the rubber which can lead to degradation over time. Additionally, rubber compounds that contain sulfur are particularly susceptible to attack by ethylene oxide, which can cause discoloration and cracking.
FFKM Perfluoroelastomer
Markez ® high performance perfluoroelastomer O-Rings (FFKM) offer unmatched value for demanding sealing applications. Produced from nearly identical ingredients as higher priced brands, Markez ® compounds are used for high temperature o-rings and high pressure o-rings and chemical resistant o-rings that deliver similar performance to major FFKM brands, with temperature resistance up to 625oF, at a significantly lower cost. Our proprietary processing allow us to supply seals under an inch in size more efficiently. Introduced exclusively to existing customers over 15 years ago, we now have the experience and capacity to offer Markez ® high temperature o-rings and high pressure o-rings to the world.
