Ethanol, also known as ethyl alcohol, grain alcohol, and drinking alcohol, is commonly used in the production of alcoholic beverages and industrial solvents, as well as in fuel and medical applications.
When rubber is exposed to ethanol, it can cause the rubber to swell and become softer due to the absorption of the ethanol into the rubber. Additionally, ethanol can cause rubber to become brittle and crack due to the alcohol’s solvent properties. Prolonged exposure to ethanol can also cause rubber to lose its elasticity, resulting in permanent deformation.
