Thermal Properties. Jörgen Bergström, in Mechanics of Solid Polymers, 2015. For example, at room temperature polybutadiene compounds generally have a higher resilience than similar natural rubber compounds.In turn this means that the polybutadiene rubbers have a lower heat build-up and this is important in tyre applications. Polybutadiene can improve low-temperature properties, resilience, and abrasion or wear resistance. Polybutadiene Rubber Production Share by Manufacturers in 2021 Figure 21. History. The good stability of disulfide bonds at room temperature preserved the physical and mechanical properties of the resulting rubber.
