Butyl alcohol, also known as sec-butyl alcohol or 2-butanol, is a clear, colorless, and flammable liquid with a characteristic odor. It is commonly used as a solvent in the printing, coating, and rubber industries and for the production of pharmaceuticals and other chemicals.
When exposed to butyl alcohol, rubber may swell, crack, harden, discolor, and become brittle. These reactions are due to the alcohol’s ability to penetrate the rubber material and cause it to break down. In extreme cases, the rubber can become brittle and can easily break apart. Additionally, the discoloration of the rubber is caused by the reaction of the alcohol with the rubber’s components.
