Fillers

In addition to rubber, fillers are the most important component in terms of quantity of a rubber compound . Fillers include carbon black, silica or mineral fillers such as talcum, kaolin and chalk. Nowadays, fillers are important components of compounds that specifically influence the processability and the physical and chemical properties of the end product. Fillers influence the Shore A hardness , the tensile strength and elongation at break, the abrasion resistance and the elasticity of the elastomer. In addition, certain types of carbon black can increase the electrical conductivity of the rubber.
