| Polystyrene butadiene copolymer is currently the most produced and widely used synthetic rubber variety. Its processing performance is comparable to natural rubber, and its wear resistance, heat resistance, aging resistance and other properties are superior to natural rubber. It is one of the best substitute rubber types for natural rubber and is often mixed with natural rubber or used alone. | |||||||||
