Glycols, also known as polyalcohols, are a class of organic compounds that are primarily used as a base for antifreeze, as a solvent, and in hydraulic and brake fluids. Common glycols include ethylene glycol and propylene glycol.
When rubber is exposed to glycols, the rubber can become brittle, swell, and crack. This can lead to a decrease in the rubber’s physical and mechanical properties, resulting in a shorter lifespan. Additionally, glycols can cause embrittlement and discoloration due to the reaction between the glycol and rubber. The rubber may also become tacky or soft due to the reaction between the glycol and the rubber.
