Epoxy resins, also referred to as polyepoxide, are a type of thermosetting resin commonly used in the manufacturing of high performance coatings and adhesives. Epoxy resins are often used in applications such as laminates and electrical insulation.
When rubber is exposed to epoxy resins, it can cause the rubber to become brittle and crack. Additionally, epoxy resins can also cause the rubber to swell and lose its strength. The rubber can also become discolored and lose its flexibility. To avoid these issues, it is important to select the appropriate type of rubber for the application, as well as to closely monitor rubber components for signs of degradation when exposed to epoxy resins.
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.
