Common names for Terephthalic Acid include Dimethyl Terephthalate, Benzene-1,4-dicarboxylic Acid and 1,4-Benzenedicarboxylic Acid. It is most commonly used in the production of polyester fibers and plastic resins.
When rubber is exposed to Terephthalic Acid, it can cause swelling, cracking and embrittlement. This is due to the acid reacting with the rubber and breaking down the cross-linking between the rubber molecules. This can lead to a loss of strength and elasticity in the rubber and ultimately cause failure.
