METHYL FORMATE Resistant O-Rings and Seals
Methyl Formate, also known as Methyl Methanoate or Formic Acid Methyl Ester, is a clear and colorless liquid with a formic acid odor. It is used as a solvent in many industries such as paint, coating, adhesive, printing ink, and pharmaceuticals. It is also used in the agricultural industry as a fumigant and to make methyl esters for use as biodiesel.
When rubber is exposed to Methyl Formate, it can cause a number of types of failure. The most common is swelling, hardening, and cracking due to the solvent's high vapor pressure. It can also cause corrosion of metal parts due to the presence of hydrochloric acid, which is a byproduct of Methyl Formate. Additionally, exposure to high temperatures can cause the rubber to degrade and become brittle, leading to cracks and tears.
