Octadecane, also known as n-eicosane, is a hydrocarbon found in waxes, lubricants, and aerosol propellants. It is widely used in the automotive and aerospace industries as a lubricant and fuel additive. When exposed to octadecane, rubber can suffer from swelling, shrinkage, a decrease in tensile strength, and a decrease in elasticity. In some cases, the rubber can become brittle leading to cracking and eventual failure. In extreme cases, the rubber can become brittle and break, leading to a complete failure of the material.
