Fillers for the rubber industry

Alongside our comprehensive range of industrial carbon blacks, we also supply a large number of active and inactive mineral fillers:

Wood-based renewable functional fillers

UPM BioMotion™ are wood-based renewable functional fillers .The Portfolio is based on biochemicals produced from certified sustainable and regional hardwood and sawmill waste.


Talc is a phyllosilicate and chemically a (naturally occurring) magnesium silicate hydrate. Due to its special properties (soft, water-repellent), talc has a wide range of uses and is used on the one hand in rubber compounds to improve the mechanical properties and on the other hand as a powdering agent or lubricant in cables.


Mica, plate-like layered silicates:
our wet-milled special type of Mica Concord 200/325 has a defined particle size, is chemically inert, resistant to heat and weather and exhibits very good electrically insulating properties.


Precipitated silicic acid:
Silicic acids exhibit a high potential for reinforcement and give rubber blends particularly high values for tensile strength, Shore hardness, tear propagation resistance and abrasion resistance.
