CINNAMIC ACID Resistant O-Rings and Seals
Cinnamic acid, also known as 3-phenylpropanoic acid, is a naturally occurring aromatic organic acid found in a variety of plants. It is commonly used in food, pharmaceuticals, and fragrances. It is also used in the production of dyes, plastics, and other chemicals.
Rubber exposed to cinnamic acid can experience degradation due to its high acidity. The polymer chains of rubber can be weakened and broken down by the acid, resulting in cracking and brittleness. The presence of moisture can exacerbate this degradation, as it can increase the acidity of the cinnamic acid. Additionally, cinnamic acid can react with rubber accelerators, resulting in the inability of the rubber to vulcanize.
