Welcome to Imerys Performance Minerals


Imerys offers a vast portfolio of minerals to enhance the properties of rubber compounds including talc, kaolin, wollastonite, conductive carbon black, calcium carbonate, mica and diatomaceous earth. 

Imerys minerals are key ingredients in rubber compounds for the production of a wide range of end products such as tires, flooring, industrial and consumer goods, cables and pharmaceutical stoppers where they improve processability, barrier properties, electrical properties, fire resistance, compression set and tear resistance.
Low environmental impact Imerys minerals have a synergistic effect with carbon black providing optimum processing and properties and a good cost-performance balance. 

Imerys minerals improve the dispersion of reinforcing fillers reducing mixing time. They enable downgauging of tire inner liners and can contribute to better fuel efficiency.
