Tobutyl alcohol, also known as 2-methyl-2-propanol or 2-methylpropane-2-ol, is a colorless, flammable, and water-soluble liquid used as a fuel and solvent in many industries. Common uses include in the production of perfumes, as a paint stripper, in the production of adhesives, and as a chemical intermediate for polymers and other products.
When rubber is exposed to tobutyl alcohol, it can experience swelling, changes in physical properties, and eventually may lead to cracking and premature failure. The swelling of rubber is caused by the solubility of the alcohol in the rubber. Additionally, the presence of alcohol can lead to changes in physical properties such as hardness, tensile strength, and elongation. This can lead to cracking and brittle failure of the rubber as it is exposed to the alcohol over time.
