NBR (nitrile rubber): Nitrile rubber is a cheap material that shows high resistance to oils and diesel at temperatures around 100°C. Nitrile rubbers show high resilience, high resistance to wear, but only medium strength. Furthermore, these rubbers have only a limited resistance to the effects of the weather and also a small resistance to solvents.
