The most common material used in timing belts is various types of rubber. Synthetic rubber, such as neoprene, is often preferred due to its superior resistance to heat and wear compared to natural rubber. The rubber provides flexibility, allowing the belt to bend around pulleys without cracking. This elasticity also contributes to a quiet operation, reducing engine noise. However, rubber's susceptibility to degradation from oil, heat, and ozone exposure necessitates the incorporation of additives and reinforcements.
