Methyl Mercaptan, also known as Methanethiol or Methyl Sulphide, is an organic compound with a strong odour that is used in the production of pesticides, flavO-Rings, and fragrances.
When rubber is exposed to Methyl Mercaptan, it can cause oxidation of the rubber, leading to cracking and brittleness. The chemical can also cause swelling and discoloration of the rubber due to its acidic nature. Additionally, prolonged exposure can cause the rubber to become brittle, leading to potential failure of the rubber seal.
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.
