Fillers
Key Building Blocks for Tailored Rubber Compounds
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.

What does the “Fillers” chapter cover in the compendium?
Fillers covers carbon blacks, light‑colored fillers and functional fillers used to tailor rubber compound properties.
Which carbon black categories are included?
The portfolio overview includes conductive carbon blacks, furnace carbon blacks and thermal carbon blacks.
What are “light‑colored fillers” in the compendium?
Light‑colored fillers include kaolins, white pigments and zinc oxides as separate sections in the overview.
What are “functional fillers” in the compendium?
Functional fillers include activators, high‑performance fillers and moisture absorbers.
Why are fillers important in rubber compounding?
Fillers are formulation levers that adjust performance, processing behaviour and application fit when combined with the polymer and rubber chemicals.
Are fillers treated as part of a system?
Yes. The compendium structure is explicitly system‑based across Synthetic Rubber, Fillers and Rubber Chemicals.
Does the compendium provide properties and applications for fillers?
Yes. The introduction states that users can explore properties and a wide range of applications for each product.
Can users navigate fillers by function rather than by product name?
Yes. The overview is organized by categories (e.g., conductive carbon blacks, activators, moisture absorbers) which supports functional navigation.
How should the Fillers chapter be used within the overall compendium?
Use it to define the reinforcement and functionality strategy, then align polymer choice and rubber chemical package for a balanced compound design.
