T-butyl catechol, also known as 2-methyl-2-(1-methylethyl) phenol, is a colorless, volatile, and flammable liquid commonly used in the production of dyes, polymers, and explosives. Common applications include in the production of polyurethane foam, as a chemical intermediate in the production of polymers, and as a fuel.
When rubber is exposed to t-butyl catechol, it can experience swelling, a decrease in tensile strength, and eventually may lead to cracking and premature failure. The swelling of rubber is caused by the solubility of the catechol in the rubber. Additionally, the presence of catechol can lead to a decrease in physical properties such as tensile strength, elongation, and hardness, which can lead to cracking and brittle failure of the rubber as it is exposed to the catechol over time.
