Fillers 

Fillers play a decisive role in defining the performance, processing behavior and functionality of modern rubber compounds. In the Nordmann Rubber Compendium, the Fillers chapter provides a comprehensive overview of reinforcing, functional and light-colored fillers used across a wide range of elastomer applications.

From carbon blacks for mechanical reinforcement, conductivity and abrasion resistance to light-colored fillers such as kaolins, barium sulfate, titanium dioxide and zinc oxide, fillers enable targeted adjustment of properties like strength, elasticity, color, insulation, permeability and durability. In addition, functional fillers support specific requirements such as activation, moisture control, wear resistance, friction reduction or electrical performance.

The compendium highlights how fillers are far more than cost optimizers: they are active formulation tools that strongly influence compound behavior, processing efficiency and end-product performance. Their effect is always closely linked to the selected polymer and rubber chemicals, making fillers an essential element in system-oriented compound design.

Explore the Fillers chapter to gain structured insight into filler types, functionality and typical application areas – and use this knowledge as a solid foundation for developing optimized rubber compounds.
