Product Description

Styrene-butadiene rubber (SBR), also known as polystyrene butadiene copolymer. Its physical structure performance, processing performance and product usage performance are close to those of natural rubber. Some properties, such as wear resistance, heat resistance, aging resistance and vulcanization speed, are even better than those of natural rubber. It can be used in combination with natural rubber and various synthetic rubbers, and is widely used in the production of tires, belts, hoses, wires and cables, medical devices and various rubber products, etc. It is the largest general-purpose synthetic rubber variety and also one of the earliest rubber varieties to achieve industrial production.
