PHENYLACETIC ACID Resistant O-Rings and Seals

Phenylacetic acid, also known as benzoic acid, is a monocarboxylic acid that is used in the production of adhesives, paints, plastics, and fragrances. It is also used as a preservative in food and as an antimicrobial agent in pharmaceuticals. Common types of rubber failure when exposed to Phenylacetic acid can include swelling, cracking, hardening, and embrittlement. Swelling of rubber materials can occur due to the absorption of the Phenylacetic acid, which can cause the rubber to become soft and pliable. Cracking and hardening can occur due to the release of oxygen, which can reduce the elasticity of the rubber and cause it to become brittle and break. Long-term exposure can also lead to the formation of weak spots in the rubber, which can lead to cracking and ultimately failure. Additionally, the phenylacetic acid can react with other chemicals in the rubber to create new compounds, which can increase the hardness and decrease the flexibility of the rubber, resulting in embrittlement.
