Isobutanol, also known as 2-methylpropan-1-ol, is a clear, colorless alcohol that is used as an industrial solvent and fuel. It is commonly found in paint strippers, industrial cleaners, and gasoline. Common industries that use isobutanol include automotive, chemical, and aerospace.
When rubber is exposed to isobutanol, the rubber can become brittle and crack, leading to failure. Additionally, the rubber may become sticky or tacky, leading to a decreased life span and a weakened seal. The rubber may also become discolored or swollen, making it difficult to maintain a seal. Additionally, isobutanol can cause swelling, which can lead to cracking and failure.
