Acetic acid, also known as ethanoic acid, is a colorless liquid with a distinct pungent odor. It is the main component of vinegar and has a wide range of industrial applications, such as in the production of vinyl acetate monomer for plastics and adhesives, printing inks, and pharmaceutical products.
When rubber materials are exposed to acetic acid at a concentration of 5%, they may experience swelling, softening, loss of strength and flexibility, ozone cracking, and solubilization. Different types of rubber materials may have varying levels of resistance to acetic acid, depending on the duration of exposure. In addition, the deterioration of rubber materials can be further accelerated by heat, light, and/or ozone when exposed to acetic acid.
