METHYL IODIDE Resistant O-Rings and Seals
Methyl Iodide, also known as Iodomethane, is a colorless, volatile liquid with a sweet smell. It is used in the pharmaceutical and chemical industries as a catalyst, a reagent, and a fumigant.
When rubber is exposed to Methyl Iodide, it can be susceptible to a number of types of failure. The solvent can cause rubber to swell and become hard due to its high vapor pressure. Additionally, the solvent can cause rubber to become brittle, leading to cracking and tearing. It can also cause corrosion of metal parts due to the presence of methyl ethyl ketone, which is a byproduct of Methyl Iodide. Finally, exposure to temperatures that are too high can cause the rubber to degrade and become more brittle.
