Butane, also known as 2, 20-dimethyl, is widely used as a fuel and aerosol propellant in a variety of industries. Its primary uses are in the automotive, camping and portable cooking industries, where it is used as a fuel for heat, light, and power.
When rubber is exposed to butane, it can cause a number of different failures. The rubber may become brittle, cracked, or discolored due to the chemical's low boiling point. It may also become swollen, softened, or hardened. In extreme cases, the rubber may even degrade and break down. Additionally, prolonged exposure to butane can cause the rubber to become permeable, leading to potential leaks.
