A wide variety of rubber compositions is used in the tire industry. The base elastomers that are commonly used consist of blends of natural rubber (NR), butadiene rubber (BR) and styrene-butadiene rubber (SBR). It is apparent that the utilization of rubber without filler does not provide good properties for any application.
Therefore, filler is used to impart better properties to rubber products, with carbon black or silica used commercially. Other ingredients with different functionalities are also incorporated into rubber compounds, depending on the application; i.e., softeners, vulcanizing agents, accelerators, activators,
retarders and antidegradants.
