Welcome to Imerys Performance Minerals


Imerys offers a vast portfolio of functional additives to enhance the properties of rubber and elastomer compounds that include air float kaolin, ball clay, calcium carbonate, diatomite, kaolin, mica and wollastonite.

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. They improve processability, barrier properties, electrical properties, fire resistance, compression set and tear resistance.

We refine and engineer these minerals through proprietary processes that influence their chemical and physical properties, including size, shape, structure and surface chemistry, to obtain the exact properties our customers require while optimizing the cost-performance ratio in their final products. 

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