As an important industrial material, rubber is widely used in tires, seals, shock absorbers and other fields. According to different sources and chemical compositions, rubber can be divided into natural rubber (NR) and synthetic rubber. As one of the synthetic rubbers, butyl rubber (IIR) plays an important role in the production of tires and inner tubes due to its superior air tightness and anti-aging properties. This article will compare the characteristics of natural rubber and butyl rubber in detail and their main differences in practical applications.
