Carbon blacks

Thanks to its reinforcing properties, carbon black is an indispensable part of the rubber industry. With our range of furnace, thermal and special carbon blacks we fully cover all areas of application.

Furnace blacks

These types of carbon black are known as the standard rubber blacks and meet the vast majority of the market demand. In addition to the internationally valid ASTM classification, a further distinction is made between highly active, active and semi-active carbon blacks.

Thermal blacks

As an inactive carbon black, thermal black makes it possible to achieve high levels of filling and has a positive influence on the permanent set characteristics.

Special carbon blacks with tailor-made properties

These products stand out from the standard ASTM carbon blacks principally because of their high purity as indicated by a low sulphur content and low sieving residue.
