Acetaldehyde, also known as ethanal, is a colorless, flammable liquid with a distinct odor. It is most commonly used in the production of acetic acid, which is used in the manufacture of food and beverages, plastic, and in the production of vinyl acetate. It is also used in the manufacture of perfumes, dyes, and medicines.
When rubber is exposed to acetaldehyde, it can suffer from a range of issues, including cracking, discoloration, and corrosion. The rubber can also become brittle and prone to failure due to the chemical’s corrosive nature. In addition, acetaldehyde can cause the rubber to swell, leading to an increase in friction and a decrease in the rubber’s ability to seal properly.
