SBR is a copolymer of styrene and butadiene and has properties similar to natural rubber. It has greater abrasion resistance than natural rubber, better wear resistance and better low temperature flexibility. Though superior in water resistance to natural rubber, it has about the same resistance to solvents and chemicals. It has better heat resistance and heat-aging qualities than natural rubber, and in excess heat it hardens and becomes brittle instead of softening. The temperature range of SBR is -55C to +70C (-67F to158F). Suitable applications include:
