Synthetic rubber is a man-made material that is designed to replicate the properties of natural rubber. It is produced from various petrochemicals and other chemicals. One of the most commonly used synthetic rubbers for conveyor belts is styrene-butadiene rubber (SBR). SBR exhibits excellent wear resistance, low heat buildup, and a high degree of flexibility, making it suitable for use in conveyor belts. Moreover, its high resistance to abrasion makes it ideal for use in heavy-duty applications.

Another commonly used synthetic rubber is ethylene-propylene-diene monomer (EPDM). EPDM has excellent weather and ozone resistance along with good electrical resistance, making it suitable for use in conveyor belts that are exposed to outdoor elements. Moreover, its low-temperature flexibility makes it suitable for use in applications where low temperatures are involved.
