Butane is also known as n-butane, methylpropane, and dimethylmethane. It is a colorless, odorless, flammable gas and is commonly used as a fuel and as a propellant.
Common types of failures when rubber is exposed to butane include softening, cracking, and discoloration. Softening occurs when the rubber becomes pliable due to prolonged exposure to the gas, making it prone to tearing and stretching. Cracking can occur due to exposure to the high temperatures created by butane combustion. Discoloration can occur due to the formation of polymers on the surface of the rubber, which can cause the rubber to become discolored.
