A petrol/benzene mixture consisting of 70% petrol and 30% benzen is commonly used as a fuel additive, solvent, and as a component in some cleaning products. It is also used in the production of plastics, adhesives, and paints.
Common failures when rubber is exposed to a petrol/benzen mixture include swelling and softening of the rubber, as well as discoloration and brittleness. Additionally, the rubber is prone to accelerated aging, which can lead to hardening and cracking of the rubber over time. The mixture is highly flammable and can cause the rubber to become susceptible to cracking and tearing due to exposure to high temperatures. The weaker concentration of benzene can also cause the rubber to become stiffer and more brittle over time.
