Pentane is a colorless and volatile hydrocarbon that is found in petroleum and is commonly used as a fuel, as a cleaning agent and as a solvent in various industries. Common names for this chemical include n-pentane, dimethyl ethane, ethylbutane and methylpropane.
When rubber is exposed to pentane, it can cause swelling of the rubber. This swelling can cause the rubber to become brittle and crack, leading to a decrease in strength, durability and performance. Additionally, prolonged exposure to pentane can cause rubber to become more susceptible to cracking and further degradation.
