Fillers are additives used to enhance the mechanical and physical properties of rubber compounds. Carbon black improves strength, abrasion resistance, and UV protection, while silica enhances wet grip and reduces rolling resistance in tires.
They are essential in almost all rubber applications, particularly in tires, industrial rubber goods, and footwear. Fillers also play a significant role in cost optimization by reducing the amount of polymer required. Their selection directly influences performance characteristics such as durability, hardness, and conductivity.
