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
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
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.
Silica
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.
"Green" Silica
Our supplier BRISIL has developed a patented process for the resource-efficient production of "green" silicas from biomass (rice husks), which are used as functional fillers in tyres, shoe soles, conveyor belts and cables. Currently, there is a production plant in the Indian district of Gujarat with a capacity of 7,400 tpa. Further production plants in Asia are being planned. A REACh registration for this product series will be completed in the near future. Currently, different types (specific surface areas of 130-200 m2/g) are produced, which are characterised by a positive 'ecological footprint' and a very good price/performance ratio.
