Heptanoic Acid is also known as Enanthic Acid and is a colorless liquid with a distinct, unpleasant odour. It is used in the manufacture of plasticisers, fragrances, and flavoring agents, as well as in the manufacture of rubber and plastics.
When rubber is exposed to Heptanoic Acid, it can suffer from oxidative attack which can cause the rubber to become brittle over time. This can lead to the rubber becoming weak and losing its original shape, leading to premature failure. Heptanoic Acid can also cause the rubber to swell and become soft, leading to a loss of strength and integrity.
