SBR stands for Styrene Butadiene Rubber. Styrene butadiene rubber sheet is a tough synthetic rubber that is often put to use in vehicle tires because of its excellent abrasion resistance qualities. Tires need to be able to handle harsh conditions over their lifetime, including rough and abrasive road surfaces and extreme outdoor weathering, including constant UV exposure. Where natural rubber falters, a synthetic rubber such as SBR is designed to excel. The durable nature of styrene butadiene rubber sheet allows it to be used in synthetic rubber products which require a higher degree of toughness
